ASTM A632 is a technical standard from ASTM International that covers seamless and welded austenitic stainless steel tubing built specifically for small-diameter applications. It is designed for gener

ASTM A484 (specifically ASTM A484/A484M) is the standard specification covering general requirements for wrought stainless steel bars, shapes, forgings, and semi-finished forging billets (excluding wi

ASTM A403 covers wrought stainless steel piping fittings including elbows, tees, reducers and caps, supporting grades such as 304L, 316L and duplex S32205. These forged fittings follow heat treatment,

ASTM A268/A268M is the standard specification covering seamless and welded nominal-wall-thickness ferritic and martensitic stainless steel tubing for general corrosion-resisting and high-temperature s

303 stainless steel is the most readily machinable austenitic stainless steel (with a high machinability rating of roughly 78% to 90% compared to standard steel), whereas 316 stainless steel is much h

316 and 316L stainless steel washers, which contain 2–3% molybdenum, offer excellent resistance to chloride corrosion and marine environments. They are the preferred fastener components for use in mar

Inox 316L contains 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and ≤0.030% carbon, providing excellent corrosion resistance and weldability.

2507 (UNS S32750) is a super duplex stainless steel with a 50/50 ferrite-austenite dual-phase microstructure and a PREN value of 41–43. Alloy 31 (UNS N08031) is a super austenitic stainless steel cont

The direct Japanese equivalent of AISI 440C is JIS SUS440C, a martensitic stainless steel with 0.95–1.20% carbon. It achieves HRC 59–62 after vacuum heat treatment. Note that VG10 and other Japanese c

AISI 440C is a high-carbon martensitic stainless steel containing approximately 0.95–1.20% carbon and 16–18% chromium. In the annealed condition, its hardness is commonly specified at a maximum of app

440A, 440B and 440C are martensitic stainless steels with rising carbon content: 0.60–0.75%, 0.75–0.95%, 0.95–1.20%. After vacuum hardening, 440A hits HRC 55–58, 440B reaches HRC 57–60, and 440C achie

316L, 317L, and 317LMN are all low-carbon austenitic stainless steels with progressively higher molybdenum (Mo) and nitrogen (N) contents. Specifically, 316L contains 2.0%–3.0% molybdenum; 317L contai
