What main types are included in advanced stainless steel?

Four mainstream types make up advanced stainless steel series. Duplex stainless steel features mixed austenite-ferrite dual phase for balanced strength and chloride corrosion resistance. Super austenitic stainless steel adds high molybdenum and nitrogen to resist severe pitting in chemical brines. Super duplex grades further upgrade alloy ratios for ultra-tough offshore working conditions. Precipitation hardening advanced stainless steel gains high hardness through low-temperature aging treatment while retaining decent anti-rust capacity. Every variant is tailored to distinct harsh media and load conditions without interchangeability in critical equipment.
