S32205 / 2205 is the most widely used duplex stainless steel, containing 22–23% chromium, 4.5–6.5% nickel, 3–3.5% molybdenum, and nitrogen. It combines ferritic and austenitic phases, offering twice the yield strength of 304/316 and significantly higher p
S32304 is a standard duplex stainless steel containing 22–24% chromium, 3–5% nickel, nitrogen, and small amounts of molybdenum. It offers excellent resistance to pitting and crevice corrosion, with a PREN value higher than 316L.
S32101 is a lean duplex stainless steel containing approximately 21–22% chromium, low nickel (1.3–1.7%), nitrogen, and manganese. It offers twice the yield strength of austenitic grades while maintaining good resistance to pitting and crevice corrosion.
420 (UNS S42000) is a high‑hardness martensitic stainless steel containing 12–14% chromium and elevated carbon levels (0.15–0.40%). It can be hardened above 50 HRC through heat treatment, offering excellent wear resistance and mechanical strength.
420 (UNS S42000) is a high‑hardness martensitic stainless steel containing 12–14% chromium and elevated carbon levels (0.15–0.40%). It can be hardened to above 50 HRC through heat treatment, making it a classic high‑hardness stainless steel.
416 (UNS S41600) is one of the most free‑machining martensitic stainless steels, enhanced with sulfur to improve turning, drilling, and threading performance. As a typical free‑machining stainless steel, it offers excellent machinability while maintaining
410 (UNS S41000) is a martensitic stainless steel containing 11.5–13.5% chromium with very low nickel content. It is heat‑treatable and capable of achieving high strength and hardness through quenching and tempering. As a classic martensitic stainless ste
430 (UNS S43000) is a ferritic stainless steel containing 16–18% chromium and no nickel, making it an economical corrosion‑resistant alloy. It offers good resistance in atmospheric and mildly corrosive environments but is less resistant to chlorides compa
310S (UNS S31008) is a high‑temperature austenitic stainless steel with 24–26% chromium and 19–22% nickel. Its high chromium‑nickel content provides outstanding oxidation resistance and structural stability during long‑term exposure at 1050–1150°C. The lo
321H (UNS S32109) is the high‑carbon, titanium‑stabilized variant of 321 stainless steel. With 17–19% chromium, 9–13% nickel, and titanium added to prevent carbide precipitation, it offers improved resistance to sensitization during high‑temperature servi
