Stainless steel rods are primarily categorized into three main types: austenitic, ferritic, and martensitic. Austenitic stainless steel is widely used due to its excellent corrosion resistance and workability.
304L is a low-carbon version, offering enhanced resistance to intergranular corrosion after welding.
316L is an ultra-low-carbon version, further enhancing corrosion resistance.
The 310 series contains up to 25% chromium, enabling stable operation at temperatures up to 800°C.
Duplex steels contain 17%-22% chromium and 5%-8% nickel, offering superior strength and corrosion resistance to ordinary stainless steels and are commonly used in marine engineering.
The 410 series (e.g., 410) offers high hardness but weaker corrosion resistance, making it commonly used in knives.
The 430 series (e.g., 430) offers outstanding wear resistance, making it suitable for decorative applications.
