SUS 304 is the most widely used austenitic stainless steel in JIS G4304 / G4312. With 18–20% chromium and 8–10.5% nickel, it is the classic 18‑8 stainless steel. It offers a balanced combination of corrosion resistance, formability, and weldability.
SUS 201 is an economical austenitic stainless steel defined in JIS G4304 / G4312. By reducing nickel and adding manganese, it forms a stable austenitic structure and becomes a typical low‑nickel stainless steel. With 16–18% chromium and 3.5–5.5% nickel, i
SUS 301L is the low‑carbon variant of SUS 301 stainless steel defined in JIS G4304 (hot‑rolled) and JIS G4312 (cold‑rolled). With 16–18% chromium, 6–8% nickel, and reduced carbon (≤0.03%), it offers improved weld‑zone corrosion resistance while maintainin
SUS 301 is the high‑strength austenitic stainless steel grade defined in JIS G4304 (hot‑rolled) and JIS G4312 (cold‑rolled). With 16–18% chromium and 6–8% nickel, it has a lower nickel content than 304, giving it superior work‑hardening behavior.
S32760 (Zeron 100) is a high‑alloy duplex stainless steel containing chromium, nickel, molybdenum, nitrogen, copper, and tungsten. With a PREN value of 40–45, it offers outstanding resistance to pitting, crevice corrosion, and stress‑corrosion cracking.
S32750 / 2507 is a super duplex stainless steel containing 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and nitrogen. With a PREN value above 40, it provides exceptional resistance to pitting, crevice corrosion, and stress‑corrosion cracking, outperform
S31803 is a standard duplex stainless steel containing 21–23% chromium, 4.5–6% nickel, 2.5–3.5% molybdenum, and nitrogen. Its performance is similar to S32205, though S32205 has a narrower and optimized composition range.
S31803 is a standard duplex stainless steel containing 21–23% chromium, 4.5–6% nickel, 2.5–3.5% molybdenum, and nitrogen. Its performance is similar to S32205, though S32205 has a narrower and optimized composition range.
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.
