SAE4340 Steel Round Bar ASTM4340 Steel Rod
Features
4340 Materia vectis ferrei est structuralis chalybs mixtura.Aequivalent to German DIN ferro gradus 36CrNiMo4, French NF vexillum 40NCD3, vexillum Iaponica JIS SNCM439, vexillum Britannicum BS 816M40, American SAE/ASTM4340, American UNS vexillum G43400，China Latin 40CrNiMoA.
SAE4340 notum est ferro stannum structurale vel ferro composito.Ferrum nickel inter 1.65 et 2.00 continet, quod magnam vim habet, duritiem, facultatem indurandi altam, firmitatem contra aestuantem.Habet tamen candoris suavitatem et animi fragilitatem.Pauperes readability, summus temperaturas preheating ante glutino requirens, levamen post glutino accentus, et usus post temperantiam.
