SS904L AISI 904L igwe anaghị agba nchara (UNS N08904)
Okwu Mmalite ngwaahịa
AISI 904L igwe anaghị agba nchara (UNS N08904) bụ nnukwu alloy austenitic igwe anaghị agba nchara. E jiri ya tụnyere 316L, SS904L nwere ọdịnaya carbon (C) dị ala, ọdịnaya chromium (Cr) dị elu, yana ihe dị ka nickel (Ni) na molybdenum (Mo) okpukpu abụọ.316L, nke na-eme ka ọ nwee elu elu okpomọkụ oxidation resistance, pitting resistance, na iguzogide ibelata acid (dịka ọmụmaatụ, sulfuric acid). Nitrogen (N) nwere ike ibelata ọnụ ọgụgụ nke chromium carbide mmiri ozuzo, si otú ahụ ibelata uche nke uche, ọ na-emekwa ka iguzogide pitting na crevice corrosion nke chlorides kpatara. Karịsịa mgbakwunye ọla kọpa (Cu) na-eme ka ọ baa uru maka mkpokọta sulfuric acid niile.
Alloy 904L na-arụ ọrụ nke ọma karịa igwe anaghị agba nchara austenitic ndị ọzọ n'ihi ntinye dị elu nke nickel na molybdenum. The ọkwa bụ na-abụghị magnetik n'ọnọdụ niile na nwere magburu onwe formability na weldability. Ọdịdị austenitic na-enyekwa ọkwa a nke ọma siri ike, ọbụna ruo na okpomọkụ cryogenic Ọdịnaya chromium dị elu na-akwalite ma na-ejigide ihe nkiri na-agafe agafe nke na-echebe ihe onwunwe n'ọtụtụ ebe na-emebi emebi. Enweghị ihe ize ndụ nke corrosion intercrystalline na jụrụ oyi ma ọ bụ ịgbado ọkụ n'ihi ọdịnaya carbon dị ala. Okpomọkụ ọrụ ya kacha dị na 450ºC. Nke a ọkwa bara uru karịsịa na njikwa na ngwa tubing ngwá ọrụ ebe 316 na 317L adịghị adabara.
Alloy 904L ka emebere na mbụ ka ọ nagide gburugburu nwere sulfuric acid dilute. Ọ na-enyekwa ezigbo iguzogide acid inorganic ndị ọzọ dị ka phosphoric acid na-ekpo ọkụ yana ọtụtụ acid organic.
Alloy 904L na-adị mfe welded ma hazie ya site na ụkpụrụ nrụpụta ụlọ ahịa.
A na-eji igwe anaghị agba nchara 904L (SS904L) na mmanụ ala, kemịkalụ, fatịlaịza, ụlọ elu mmepe mmiri, tankị, ọkpọkọ na tubes na ndị na-ekpo ọkụ. Rolex na ndị nrụpụta elekere ndị ọzọ na-ejikwa ya eme elekere
