International Stainless Steel Marking Method The American Iron and Steel Institute uses three digits to mark various standard grades of forgeable stainless steel. Among them: ①Austenitic stainless steels are marked with 200 and 300 series numbers. For example, some of the more common austenitic stainless steels are marked with 302, 304, 316 and 310, ②Ferritic and martensitic stainless steels are used The number of the 400 series is represented. ③Ferritic stainless steel is marked with 430 and 446, martensitic stainless steel is marked with 410, 420 and 440C, duplex (austenite-ferrite), ④Stainless steel, precipitation hardening stainless steel and low iron content Less than 50% of the high alloys usually use a patent name or a brand name.
Stainless steel will not produce corrosion, pitting, rust or wear. Stainless steel is also one of the strongest materials among the metal materials used in construction. Because stainless steel has good corrosion resistance, it can make structural components permanently maintain the integrity of the engineering design. Chromium-containing stainless steel also combines mechanical strength and high extensibility, easy to process and manufacture parts, and can meet the needs of architects and structural designers.
