The 400 series of stainless steels is known for its high strength, wear resistance, and magnetic properties. These alloys, which include 410 and 430, are ferritic and martensitic, containing higher levels of carbon and chromium. Stainless Steel 400 series is often used in automotive exhaust systems, kitchen utensils, and structural components. Its ability to withstand high temperatures and corrosive environments makes it a reliable option for demanding industrial applications.
