This layer prevents corrosion and rust, distinguishing stainless steel from ordinary carbon steel. Depending on alloying elements (e.g., nickel, molybdenum, titanium, manganese, or nitrogen), stainless steel can be categorized into different grades with tailored properties, making it widely used in industries such as construction, automotive, aerospace, food processing, medical equipment, and marine engineering.Key CharacteristicsCorrosion ResistanceThe chromium oxide layer provides excellent resistance to rust, oxidation, and corrosion in various environments (e.g., humid air, water, chemicals). Alloys with molybdenum (e.g., 316) offer enhanced resistance to chloride-induced corrosion (e.g., seawater, salt spray).Mechanical PropertiesHigh tensile strength and ductility, with some grades (e.g., duplex stainless steels) offering superior strength compared to austenitic grades. Good impact resistance even at low temperatures for austenitic types.Heat ResistanceMany grades retain strength and corrosion resistance at high temperatures (e.g., 310 stainless steel withstands up to 1100°C), making them suitable for furnace parts, boilers, and exhaust systems.WorkabilityExcellent formability, weldability, and machinability (varies by grade: austenitic grades like 304 are highly weldable; ferritic grades like 430 are easier to machine).Aesthetic AppealSmooth, bright surface finish (e.g., polished, brushed) ensures long-lasting visual quality, ideal for architectural, decorative, and consumer goods applications.Hygiene & CleanlinessNon-porous surface resists bacterial growth, meeting strict standards for food processing, pharmaceuticals, and medical equipment.Stainless steel SurfaceStainless steel comes in various surfaces such as 2B, BA, 8K, 16K and brushed, and there are also multiple colors to choose from.SpecificationCatagoryTypical ApplicationsGB Designation (China)ASTM Grade (USA)EN Designation (EU)Key AlloysAustenitic (Most Common)Food equipment, architecture, chemical tanks06Cr19Ni10304X5CrNi18-10Cr: 18-20%, Ni: 8-10%Marine, coastal, high-corrosion environments06Cr17Ni12Mo2316X5CrNiMo17-12-2Cr: 16-18%, Ni: 10-14%, Mo: 2-3%High-temperature/corrosion (e.g., heat exchangers)06Cr17Ni12Mo2Ti316TiX6CrNiMoTi17-12-2+ Ti (stabilizer)FerriticAutomotive trim, kitchen appliances06Cr13410X10Cr13Cr: 11.5-13.5%Decorative, low-cost corrosion resistance022Cr12430X2CrNi12Cr: 11-13%, Low CMartensiticCutlery, valves, surgical tools12Cr13420X20Cr13Cr: 12-14%, Higher CDuplexOil & gas, desalination (high strength/corrosion)022Cr22Ni5Mo3NS31803X2CrNiMoN22-5-3Cr: 21-23%, Ni: 4.5-6.5%, Mo: 2.5-3.5%Application ScenariosAutomotive industryHome appliance industryAutomotive insulation panels, engine components,chassis components, etc.Oven and stove shells, toasters, barbecue grills,internal heating components of microwave ovens, etc.Construction industryIndustrial equipmentRoofs, firewall panels, insulation panels,etc. used in high-temperature environments.Drying equipment, industrial equipment used in high-temperature environments.Packing & DeliveryCompany ProfileFAQ1.Why doesn't stainless steel rust?Stainless steel resists rust due to its high chromium content (minimum 10.5%). When exposed to oxygen, chromium forms a thin, invisible passive oxide layer on the surface, which self-heals if damaged (e.g., scratched). This layer blocks further oxidation and corrosion. Alloys with added molybdenum (e.g., 316) enhance resistance to harsh environments like saltwater or chemicals.2.What's the difference between 304 and 316 stainless steel?Both are austenitic (non-magnetic, highly workable) but differ in alloying elements. 304 contains ~18-20% chromium and 8-10% nickel, ideal for general use (e.g., kitchenware, architecture). 316 adds 2-3% molybdenum, boosting resistance to chloride corrosion (e.g., seawater, coastal areas, chemical tanks). 316 is more expensive but better for high-corrosion environments.3.How do I clean and maintain stainless steel products?Use mild detergents (e.g., soap and water) or specialized stainless steel cleaners. Avoid abrasive tools (steel wool) or harsh chemicals (chlorine bleach, hydrochloric acid), as they can damage the passive layer. For stubborn stains, wipe with a soft cloth and dry immediately to prevent water spots. Regular cleaning preserves shine and corrosion resistance.4.Is stainless steel magnetic?It depends on the grade. Austenitic stainless steel (e.g., 304, 316) is generally non-magnetic due to its crystal structure. Ferritic (e.g., 430) and martensitic (e.g., 420) grades are magnetic because of their higher chromium and lower nickel content. Cold working (e.g., bending) may make austenitic grades slightly magnetic temporarily, but this doesn't affect performance.
