ASTM A213, A269 904L igwe anaghị agba nchara na China
Alloy 904L bụ igwe anaghị agba nchara, akwa alloy austenitic igwe anaghị agba nchara nwere obere carbon ọdịnaya.A na-eji ya eme ihe na ngwa ebe njirimara corrosion nke TP316/L na TP317/L ezughị oke.Alloy ahụ na-enyekwa ezigbo nhazi, weldability, na ike.Mgbakwunye ọla kọpa na-enye alloy 904L corrosion eguzogide ihe ndị dị elu karịa igwe anaghị agba nchara chrome nickel.Ọmụmatụ gụnyere iguzogide sọlfọ, phosphoric, na acetic acid.
