China Flat Steel Bar AISI 4330 Forged Steel Bar

AISI ASTM 4330 Engineering Steel1: AISI 4330 steel introduction
Alloy Steel 4330, also sold as AISI 4330, is a high-strength, chromium, nickel, and molybdenum alloy. Alloy Steel 4330 is heat-treatable, and offers good formability. The alloy is machinable in the annealed, normalized, and tempered conditions, but not as easily in a hardened condition. Users will find that welding is possible by most conventional methods.2: AISI 4330 Steel equivalentCountryChinaJapanGermanyUSABritishStandardGB/T 3077JIS G4105DIN (W-Nr.)
