Frequently Asked Questions (FAQ)
What are the main categories of stainless steel?
Stainless steel is generally divided into five major categories based on its crystalline structure: Austenitic, Ferritic, Martensitic, Duplex, and Precipitation Hardening stainless steel.
How do standard designations compare between China (GB) and the USA (ASTM)?
Standard grades correspond across systems. For example, the popular Chinese GB grade 06Cr19Ni10 corresponds directly to the American ASTM/AISI grade 304 (UNS S30400), and the Chinese 022Cr17Ni12Mo2 corresponds to ASTM 316L.
What is the difference between Austenitic and Ferritic stainless steel?
Austenitic stainless steels (like 304 and 316) offer high oxidation resistance, are non-magnetic, and are highly cleanable. Ferritic stainless steels (like 430) contain chromium as the main alloying element, are magnetic, and offer moderate corrosion resistance at a lower cost.
What makes Duplex stainless steel unique?
Duplex stainless steel features a mixed microstructure of austenite and ferrite in equal proportions. This provides higher strength and significantly better resistance to stress corrosion cracking compared to standard austenitic grades.
Where is Martensitic stainless steel commonly used?
Martensitic stainless steels (like 410 and 420) are heat-treatable to high hardness levels. They are commonly used in applications requiring wear resistance and edge retention, such as cutlery, surgical instruments, and fasteners.
