that most directly controls surface profile depth in abrasive blasting \u2014 and surface profile depth is one of the most critically specified variables in industrial coating application and shot peening. Selecting the wrong grit size produces a profile either too shallow for adequate coating adhesion, or unnecessarily deep \u2014 wasting abrasive and creating coating thickness variation that compromises service life.<\/p>\n  <p>Despite being critically important, abrasive particle sizing is one of the most frequently misunderstood aspects of blasting media specification. Different industries, regions, and media types use different sizing standards \u2014 FEPA, ANSI, US Mesh, JIS, SAE \u2014 that are not directly interchangeable. Specifying &#8220;60 grit&#8221; without naming the standard invites the wrong media: FEPA F60 and US Mesh 60 are different particle sizes, and using one where the other is intended will produce incorrect results.<\/p>\n  <p>This guide resolves that ambiguity by covering all major standards, providing full conversion tables, and mapping grit sizes to the surface profiles and applications they produce. For broader context on media selection beyond sizing, see: <a class=\"hlh-link\" href=\"https:\/\/hlh-js.com\/resource\/blog\/abrasive-blasting-media-complete-guide-to-types-properties-selection\/\" target=\"_blank\" rel=\"noopener\">Abrasive Blasting Media Complete Guide<\/a>.<\/p>\n\n  <h2 id=\"how-sizing-works\">How Abrasive Particle Sizing Works<\/h2>\n  <p>Abrasive particle size is determined by sieve analysis \u2014 passing the material through a series of standardized wire mesh screens with precisely defined opening sizes. Particles that pass through a given sieve but are retained on the next finer sieve are classified as belonging to that size fraction.<\/p>\n  <p>The fundamental unit is the <strong>sieve opening size in microns (\u00b5m)<\/strong>, the actual physical dimension of particles in a given fraction. All sizing standards ultimately reference micron dimensions, even though they label products differently.<\/p>\n  <p>The single most important principle to remember: <strong>higher grit or mesh number = smaller particles = finer finish and shallower profile.<\/strong> Lower number = larger particles = coarser, deeper profile. This inverse relationship is consistent across all standards, even though the numbers themselves differ.<\/p>\n\n  <div class=\"hlh-box hlh-box-blue\">\n    <div class=\"hlh-box-title\">The Inverse Relationship: Higher Number = Finer Grit<\/div>\n    <p>The number represents sieve openings per linear inch \u2014 more openings per inch means smaller openings, meaning only smaller particles pass through. So <strong>F120 grit is finer than F36<\/strong>, just as US 120 mesh is finer than US 36 mesh. The intuition that &#8220;bigger number = bigger particle&#8221; is wrong for all abrasive sizing systems.<\/p>\n  <\/div>\n\n  <h2 id=\"standards\">Major Sizing Standards Explained<\/h2>\n\n  <h3>FEPA (Federation of European Producers of Abrasives) \u2014 F-Series<\/h3>\n  <p>FEPA is the primary standard for synthetic abrasives \u2014 aluminum oxide and silicon carbide \u2014 in Europe and internationally. The <strong>F-series<\/strong> (free abrasive grain) applies to blasting, lapping, and polishing applications. FEPA F-grit sizes run from F4 (very coarse, ~4,000 \u00b5m) through F1200 (ultra-fine, ~4 \u00b5m). Jiangsu Henglihong Technology uses FEPA for all aluminum oxide and silicon carbide product specifications.<\/p>\n\n  <h3>ANSI (American National Standards Institute) \u2014 B74.12<\/h3>\n  <p>ANSI B74.12 defines abrasive grain sizes for the US market. ANSI grade designations (ANSI 36, 60, 80, etc.) roughly correspond to FEPA F-series numbers in nominal particle size, but particle size distribution requirements differ slightly. For most industrial applications the two are functionally interchangeable at the same grade number, but strict compliance specifications require confirming which standard governs.<\/p>\n\n  <h3>US Mesh (ASTM E11 \/ Tyler Mesh)<\/h3>\n  <p>US mesh sizing is used primarily for glass beads, garnet, walnut shell, corn cob, and other non-synthetic media. The mesh number equals openings per linear inch in the sieve screen. Blasting applications use US mesh from approximately 6 (coarse, ~3,360 \u00b5m) through 400 (ultra-fine, ~37 \u00b5m). Garnet is commonly specified in double-fraction notation (e.g., 30\/60 \u2014 retained on US 30, passing US 60 \u2014 equivalent to 250\u2013600 \u00b5m particle range).<\/p>\n\n  <h3>SAE (Society of Automotive Engineers)<\/h3>\n  <p>SAE standards govern steel shot and steel grit sizing. Steel shot grades are designated S-110 through S-780; steel grit grades G-10 through G-120. SAE J827 (shot) and SAE J1993 (grit) define each grade&#8217;s size distribution. ISO equivalents are ISO 11124-2 (steel grit) and ISO 11124-3 (steel shot).<\/p>\n\n  <h3>JIS (Japanese Industrial Standard) \u2014 R6001<\/h3>\n  <p>JIS R6001 is closely aligned with FEPA F-series for most commercial blasting grades. JIS uses the same grade designation numbers as FEPA at common sizes (JIS #36 \u2248 FEPA F36). For cross-border procurement involving Japanese manufacturers or specifications, JIS and FEPA are largely interchangeable at equivalent grade numbers.<\/p>\n\n  <h2 id=\"fepa-chart\">FEPA Grit Size Chart \u2014 Aluminum Oxide &amp; Silicon Carbide<\/h2>\n  <div class=\"hlh-table-wrap\">\n    <table>\n      <thead>\n        <tr><th>FEPA Grade<\/th><th>Nominal D50 (\u00b5m)<\/th><th>Sieve Range (\u00b5m)<\/th><th>ANSI Equiv.<\/th><th>JIS Equiv.<\/th><th>Profile Ra (\u00b5m)<\/th><th>Primary Blasting Use<\/th><\/tr>\n      <\/thead>\n      <tbody>\n        <tr><td class=\"td-bold\">F12<\/td><td>1,700<\/td><td>1,400\u20132,360<\/td><td>ANSI 12<\/td><td>#12<\/td><td>100\u2013160<\/td><td>Very heavy scale, extreme profiling<\/td><\/tr>\n        <tr><td class=\"td-bold\">F16<\/td><td>1,180<\/td><td>1,000\u20131,700<\/td><td>ANSI 16<\/td><td>#16<\/td><td>80\u2013130<\/td><td>Heavy mill scale removal<\/td><\/tr>\n        <tr><td class=\"td-bold\">F24<\/td><td>710<\/td><td>600-850<\/td><td>ANSI 24<\/td><td>#24<\/td><td>60\u2013100<\/td><td>Aggressive rust\/scale removal<\/td><\/tr>\n        <tr><td class=\"td-bold\">F30<\/td><td>589<\/td><td>500-710<\/td><td>ANSI 30<\/td><td>#30<\/td><td>50\u201385<\/td><td>Heavy coating prep<\/td><\/tr>\n        <tr><td class=\"td-bold\">F36<\/td><td>500<\/td><td>425-600<\/td><td>ANSI 36<\/td><td>#36<\/td><td>40\u201375<\/td><td>Standard coating prep (Sa 2.5), thermal spray<\/td><\/tr>\n        <tr><td class=\"td-bold\">F46<\/td><td>390<\/td><td>355-500<\/td><td>ANSI 46<\/td><td>#46<\/td><td>35\u201360<\/td><td>General industrial blasting<\/td><\/tr>\n        <tr><td class=\"td-bold\">F54<\/td><td>340<\/td><td>300-425<\/td><td>ANSI 54<\/td><td>#54<\/td><td>28\u201350<\/td><td>Medium-duty coating prep<\/td><\/tr>\n        <tr><td class=\"td-bold\">F60<\/td><td>268<\/td><td>250-355<\/td><td>ANSI 60<\/td><td>#60<\/td><td>22\u201342<\/td><td>Precision coating prep, light deburring<\/td><\/tr>\n        <tr><td class=\"td-bold\">F80<\/td><td>196<\/td><td>180-250<\/td><td>ANSI 80<\/td><td>#80<\/td><td>14\u201328<\/td><td>Precision deburring, pre-plate conditioning<\/td><\/tr>\n        <tr><td class=\"td-bold\">F100<\/td><td>154<\/td><td>125-180<\/td><td>ANSI 100<\/td><td>#100<\/td><td>10\u201320<\/td><td>Fine surface prep, lapping prep<\/td><\/tr>\n        <tr><td class=\"td-bold\">F120<\/td><td>127<\/td><td>106-150<\/td><td>ANSI 120<\/td><td>#120<\/td><td>8\u201315<\/td><td>Fine deburring, pre-anodizing<\/td><\/tr>\n        <tr><td class=\"td-bold\">F150<\/td><td>97<\/td><td>75\u2013125<\/td><td>ANSI 150<\/td><td>#150<\/td><td>5\u201312<\/td><td>Satin surface conditioning<\/td><\/tr>\n        <tr><td class=\"td-bold\">F180<\/td><td>78<\/td><td>63-90<\/td><td>ANSI 180<\/td><td>#180<\/td><td>4\u20139<\/td><td>Fine finishing, pre-polish prep<\/td><\/tr>\n        <tr><td class=\"td-bold\">F220<\/td><td>58<\/td><td>45\u201375<\/td><td>ANSI 220<\/td><td>#220<\/td><td>3\u20137<\/td><td>Ultra-fine conditioning<\/td><\/tr>\n        <tr><td class=\"td-bold\">F280\u2013F1200<\/td><td>4\u201340<\/td><td>\u2014<\/td><td>ANSI 240\u20131200<\/td><td>#240+<\/td><td>&lt;5<\/td><td>Lapping, polishing, optical surface finishing<\/td><\/tr>\n      <\/tbody>\n    <\/table>\n  <\/div>\n\n  <h2 id=\"mesh-chart\">US Mesh Size Chart \u2014 Glass Bead &amp; Garnet<\/h2>\n  <div class=\"hlh-table-wrap\">\n    <table>\n      <thead>\n        <tr><th>US Mesh Size<\/th><th>Sieve Opening (\u00b5m)<\/th><th>Approx.

Higher numbers mean smaller particles and shallower, finer finishes; lower numbers mean larger particles and deeper, coarser profiles. F36 aluminum oxide has much larger particles and cuts more aggressively than F120, despite F120 having the higher number.<\/div>\n    <\/div>\n    <div class=\"hlh-faq-item\">\n      <button class=\"hlh-faq-q\" onclick=\"hlhB5Toggle(this)\">What is the difference between grit size and mesh size?<span class=\"hlh-faq-arrow\">\u25bc<\/span><\/button>\n      <div class=\"hlh-faq-a\">Both describe particle dimensions but use different numbering systems and distribution standards. FEPA F36 and US Mesh 35 are approximately the same nominal particle size (~500 \u00b5m) but have different particle size distribution requirements. They are not exact substitutes on critical specifications \u2014 always specify the governing standard alongside the grade number to avoid ambiguity.<\/div>\n    <\/div>\n    <div class=\"hlh-faq-item\">\n      <button class=\"hlh-faq-q\" onclick=\"hlhB5Toggle(this)\">How do I convert FEPA grit to US mesh size?<span class=\"hlh-faq-arrow\">\u25bc<\/span><\/button>\n      <div class=\"hlh-faq-a\">Use particle size in microns as the common reference: F36 \u2248 500 \u00b5m \u2248 US 35 mesh; F60 \u2248 268 \u00b5m \u2248 US 50 mesh; F80 \u2248 196 \u00b5m \u2248 US 80 mesh; F120 \u2248 127 \u00b5m \u2248 US 120 mesh; F220 \u2248 58 \u00b5m \u2248 US 230 mesh.
