But, the 400 series stainless steel grades are iron-based alloys known for strength, wear resistance, and magnetic behavior.<\/p>\n<p>They usually contain about 11 to 27 percent chromium with higher carbon and little-to-no nickel. That chemistry makes them tougher and more abrasion-resistant than many other stainless types. But, they\u2019re slightly less resistant to rust in harsh environments.<\/p>\n<p>Because of their structure, these steels can be hardened, which boosts strength and durability for mechanical parts. Many grades also handle heat well and resist scaling during high-temperature use. In short, they\u2019re chosen when toughness, hardness, and cost efficiency matter more than maximum corrosion protection.<\/p>\n<p>For you to have a better and more specific understanding of it, here are the different grades of 400 series stainless steels.<\/p>\n<p>\u00c0 lire \u00e9galement\u00a0: <a href=\"https:\/\/hdcmfg.com\/fr\/ressources\/blog\/acier-inoxydable-303-contre-304\/\"><u>Acier inoxydable 303 vs 304 : sont-ils identiques ?<\/u><\/a><\/p>\n<h2>400 Series Stainless Steel Grades<\/h2>\n<p><iframe title=\"Ferritic Stainless Steels 400 Series - Guide to Stainless Steel\" src=\"https:\/\/www.youtube.com\/embed\/sOmMWkmIzIU\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><br \/>\nThe 400 series stainless steels are known for strength, wear resistance, and magnetic properties. So, if you\u2019re interested to learn more about the different grades of the 400 stainless steel family, here they are!<\/p>\n<h3>Acier inoxydable 409<\/h3>\n<p>409 is commonly used where heat resistance matters more than appearance. It handles high temperatures well and resists oxidation, meaning, it\u2019s often found in exhaust systems and automotive components. It\u2019s not the most corrosion-resistant grade, but it performs reliably in mild environments.<\/p>\n<p><strong><b>Utilisations typiques\u00a0:<\/b><\/strong><\/p>\n<ul>\n<li>Exhaust systems and mufflers<\/li>\n<li>Furnace components<\/li>\n<li>Heat exchanger tubing<\/li>\n<li>Structural supports<\/li>\n<\/ul>\n<h3>Acier inoxydable 410<\/h3>\n<p>Strength is what draws people to 410. Once heat-treated, it becomes hard and wear resistant, yet still machinable enough for production work. It resists mild chemicals and steam, so it fits applications where stress matters more than appearance.<\/p>\n<p><strong><b>Utilisations typiques\u00a0:<\/b><\/strong><\/p>\n<ul>\n<li>Bolts and fasteners<\/li>\n<li>Pump and valve parts<\/li>\n<li>Cutlery and tools<\/li>\n<li>Turbine components<\/li>\n<\/ul>\n<h3>410S Stainless Steel<\/h3>\n<p>Yes, 410 and 410S are separate. When you want a grade that has good weldability, 410S is the answer. Its lower carbon content keeps it softer and less prone to cracking during fabrication or heat exposure. So it\u2019s commonly selected for parts that must stay stable during thermal cycling.<br \/>\n<strong><b>Utilisations typiques\u00a0:<\/b><\/strong><\/p>\n<ul>\n<li>Heat processing equipment<\/li>\n<li>Distillation trays<\/li>\n<li>Petrochemical components<\/li>\n<li>Structural panels<\/li>\n<\/ul>\n<h3>Acier inoxydable 416<\/h3>\n<p>416 stands out for machinability. Sulfur is added to the mix to make it easier to cut and shape, helpinh in high-volume production. Because of that, it\u2019s often used for precision parts like gears, shafts, and fittings where clean machining is critical.<br \/>\n<strong>Utilisations typiques\u00a0:<\/strong><\/p>\n<ul>\n<li>Gears and shafts<\/li>\n<li>Valve components<\/li>\n<li>Fasteners and studs<\/li>\n<li>Motor parts<\/li>\n<\/ul>\n<h3>Acier inoxydable 420<\/h3>\n<p>Need hardness? That\u2019s where 420 stands out. Thanks to its higher carbon content, you can heat-treat it to achieve excellent edge retention and wear resistance. Corrosion resistance is lower than some grades, but its strength makes it valuable for cutting tools.<br \/>\n<strong><b>Utilisations typiques\u00a0:<\/b><\/strong><\/p>\n<ul>\n<li>Knife blades<\/li>\n<li>Surgical instruments<\/li>\n<li>Shear blades<\/li>\n<li>Hand tools<\/li>\n<\/ul>\n<h3>Acier inoxydable 430<\/h3>\n<p>430 is one of the most widely used ferritic stainless steels in the market. It offers good corrosion resistance, decent formability, and a smooth surface finish. You\u2019ll often see it in kitchen equipment, appliances, and decorative trim where appearance matters.<br \/>\n<strong>Utilisations typiques\u00a0:<\/strong><\/p>\n<ul>\n<li>Appliance panels<\/li>\n<li>Automotive trim<\/li>\n<li>Kitchen equipment<\/li>\n<li>Decorative hardware<\/li>\n<\/ul>\n<h3>431 Stainless Steel<\/h3>\n<p>431 stands out for strength and toughness. It handles high torque and stress better than many stainless grades, especially after heat treatment. Because of that, it\u2019s often used for shafts, aerospace hardware, and structural components.<br \/>\n<strong><b>Utilisations typiques\u00a0:<\/b><\/strong><\/p>\n<ul>\n<li>Aircraft fasteners<\/li>\n<li>Shafts and spindles<\/li>\n<li>Marine fittings<\/li>\n<li>Pump components<\/li>\n<\/ul>\n<h3>440 Series Stainless Steel<\/h3>\n<p>Moving into higher carbon territory, the 440 grades focus on hardness and wear resistance. Variants like 440A, 440B, and 440C increase in strength as carbon rises. And yes, 440C is especially valued where durability and edge life are critical.<br \/>\n<strong><b>Utilisations typiques\u00a0:<\/b><\/strong><\/p>\n<ul>\n<li>Precision bearings<\/li>\n<li>Knife blades<\/li>\n<li>Outils de coupe<\/li>\n<li>Measuring instruments<\/li>\n<\/ul>\n<p>\u00c0 lire \u00e9galement\u00a0: <a href=\"https:\/\/hdcmfg.com\/fr\/ressources\/blog\/types-dacier-inoxydable\/\"><u>Guide des 5 types d&#039;acier inoxydable\u00a0: propri\u00e9t\u00e9s, nuances et applications<\/u><\/a><\/p>\n<h2>300 Series vs. 400 Series Stainless Steel<\/h2>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-101245 aligncenter\" src=\"https:\/\/hdcmfg.com\/wp-content\/uploads\/2026\/02\/400-Series-Stainless-Steel-Parts.webp\" alt=\"pi\u00e8ces en acier inoxydable de la s\u00e9rie 400\" width=\"1024\" height=\"576\" srcset=\"https:\/\/hdcmfg.com\/wp-content\/uploads\/2026\/02\/400-Series-Stainless-Steel-Parts.webp 1024w, https:\/\/hdcmfg.com\/wp-content\/uploads\/2026\/02\/400-Series-Stainless-Steel-Parts-768x432.webp 768w, https:\/\/hdcmfg.com\/wp-content\/uploads\/2026\/02\/400-Series-Stainless-Steel-Parts-18x10.webp 18w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p style=\"text-align: center;\">Source: <a href=\"https:\/\/www.linkedin.com\/pulse\/300-400-stainless-steel-better-tuofa-technology-co-ltd--lpo9c\/\"><u>LinkedIn<\/u><\/a><\/p>\n<p>Both 300 and 400 series stainless steels are almost the same in terms of usage.
