ALOY 904L • UNS N08904 • WNR 1.4539

UNS NO8904, nke a na-akpọkarị 904L, bụ obere carbon high alloy austenitic igwe anaghị agba nchara nke a na-ejikarị eme ihe na ngwa ebe njirimara corrosion nke AISI 316L na AISI 317L ezughị oke.

Mgbakwunye ọla kọpa na ọkwa a na-enye ya ihe ndị na-eguzogide corrosion kariri igwe anaghị agba nchara chrome nickel, karịsịa na sulphuric, phosphoric na acetic acid. Agbanyeghị, enwere obere ojiji na hydrochloric acid. Ọ na-enwekwa nnukwu nguzogide pitting na ngwọta chloride, nguzogide dị elu nke ma crevic na nrụgide corrosion cracking. Alloy 904L na-arụ ọrụ nke ọma karịa igwe anaghị agba nchara austenitic ndị ọzọ n'ihi njupụta dị elu nke nickel na molybdenum.
