A182 F45 S30815 253 MA
May 10, 2023
Stainless hlau 253 MA, Stainless hlau qib 253MA, UNS S30815
A182 F45 S30815 yog qib stainless hlau cov khoom uas tau them los ntawm A182 specification rau forged fittings, flanges, thiab lwm yam siab-muaj qhov chaw. Cov khoom tseem hu ua UNS S30815 los yog Alloy 253MA, thiab nws yog ib tug high-kub austenitic stainless hlau uas muaj zoo heev zog, toughness, thiab kuj mus oxidation.
253 MA tuav nws cov khoom tiv thaiv tshav kub los ntawm kev tswj hwm ntawm micro alloy ntxiv. Kev siv cov hlau tsis tshua muaj hauv ntiaj teb ua ke nrog silicon muab S30815 superior oxidation tsis kam mus txog 2000 degree F. Nitrogen, carbon thiab dispersion ntawm lub ntiaj teb tsis tshua muaj thiab alkali hlau oxides ua ke los muab creep rupture zog piv rau cov npib tsib xee puag alloys. Ntau yam khoom siv uas xav tau lub zog siab ntawm qhov kub siab xws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom siv hauv qhov cub yog cov ntawv siv rau F45 253 MA.
A182 S30815 yog tsim los siv rau hauv cov kev siv kub kub xws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam khoom siv uas ua haujlwm kub txog li 1100 degree (2012 degree F). Stainless hlau 253MA kuj tseem tsim nyog siv rau hauv cov ntawv thov uas cuam tshuam rau qhov chaw corrosive, xws li cov chaw tsim tshuaj thiab cov chaw tsim hluav taws xob.
Cov253 MA Stainless Flangemuaj kev sib xyaw ua ke ntawm cov khoom xws li chromium, npib tsib xee, thiab nitrogen, uas muab kev tiv thaiv zoo rau oxidation, scaling, thiab corrosion. Qhov sib ntxiv ntawm cov hlau tsis tshua muaj hauv ntiaj teb xws li cerium thiab lanthanum txhim kho qhov kub thiab txias zog thiab tiv thaiv thermal shock ntawm UNS S30815.
