Their chromium, nickel and molybdenum ranges are exactly the same. The only difference is in carbon \u2014 and the letter \u201cL\u201d says precisely that: <em>low carbon<\/em>.<\/p>\n<h3>Why does carbon matter?<\/h3>\n<p>In AISI 316 carbon is <strong>max 0.08%<\/strong>, in AISI 316L <strong>max 0.03%<\/strong>. The difference looks small, but its consequence is large.<\/p>\n<p>When stainless steel is welded, the zone next to the weld passes through the 450\u2013850 \u00b0C range. At that temperature carbon combines with chromium and forms <strong>chromium carbides<\/strong> at the grain boundaries. Chromium tied up in carbides can no longer protect the surface; the grain boundaries become depleted in chromium and that zone becomes open to corrosion. This is called <strong>intergranular corrosion<\/strong> (sensitisation), and it can appear as a leak months after welding.<\/p>\n<p>Because carbon is already very low in 316L, the amount of carbide that can form is negligible. That is why 316L is preferred for welded parts that cannot be solution annealed afterwards.<\/p>\n<h3>The price: some strength<\/h3>\n<p>Carbon also contributes to strength. According to our datasheets the tensile strength of 316 is <strong>515 MPa<\/strong> and its yield strength <strong>205 MPa<\/strong>, while in 316L those values are <strong>485 MPa<\/strong> and <strong>170 MPa<\/strong>. Elongation, hardness, density and the thermal properties are identical.<\/p>\n<h3>Comparison in numbers<\/h3>\n<div style=\"overflow-x:auto;border:1px solid #d7dfe4;background:#fff;margin:10px 0 26px;\">\n<table style=\"border-collapse:collapse;width:100%;font-size:15px;\">\n<thead>\n<tr style=\"background:#DD3333;color:#fff;\">\n<th style=\"padding:12px 14px;text-align:left;color:#ffffff !important;background:#DD3333;\">PROPERTY<\/th>\n<th style=\"padding:12px 14px;text-align:left;color:#ffffff !important;background:#DD3333;\">AISI 316<\/th>\n<th style=\"padding:12px 14px;text-align:left;color:#ffffff !important;background:#DD3333;\">AISI 316L<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;font-weight:600;color:#20303c;\">Carbon (C)<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">max 0.08%<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">max 0.03%<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;font-weight:600;color:#20303c;\">Chromium (Cr)<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">16.0 \u2013 18.0%<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">16.0 \u2013 18.0%<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;font-weight:600;color:#20303c;\">Nickel (Ni)<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">10.0 \u2013 14.0%<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">10.0 \u2013 14.0%<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;font-weight:600;color:#20303c;\">Molybdenum (Mo)<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">2.0 \u2013 3.0%<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">2.0 \u2013 3.0%<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;font-weight:600;color:#20303c;\">Tensile strength Rm<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">515 MPa<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">485 MPa<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;font-weight:600;color:#20303c;\">Yield strength Rp0.2<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">205 MPa<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">170 MPa<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;font-weight:600;color:#20303c;\">Elongation A50<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">40%<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">40%<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;font-weight:600;color:#20303c;\">Hardness<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">max 217 HB<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">max 217 HB<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;font-weight:600;color:#20303c;\">UNS<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">S31600<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">S31603<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;font-weight:600;color:#20303c;\">W.Nr (DIN\/EN)<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">1.4401<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">1.4404<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;font-weight:600;color:#20303c;\">AMS<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">5648 (bar, forging) \u00b7 5524 (plate, sheet) \u00b7 5573 (tube)<\/td>\n<td style=\"padding:11px 14px;border-bottom:1px solid #d7dfe4;color:#41525c;\">5653 (bar, forging) \u00b7 5507 (plate, sheet)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p style=\"font-size:13px;color:#6b7a84;margin-top:-16px;\">Values are taken from our product datasheets; section thickness and the applied heat treatment regime change the result.<\/p>\n<h3>Which one, and when?<\/h3>\n<p><strong>AISI 316 is preferred<\/strong> \u2014 parts that are not welded, or that can be solution annealed after welding: machined components, shafts, fasteners, forgings.
