253 MA Stainless Txheej txheem cej luam

Stainless 253 MA yog ib qho austenitic tshav kub resistant alloy nrog siab zog thiab zoo heev oxidation kuj. 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 kev tiv thaiv oxidation zoo txog li 2000 degree F. Nitrogen, carbon thiab dispersion ntawm lub ntiaj teb tsis tshua muaj thiab alkali hlau oxides sib xyaw ua ke los muab cov creep rupture zog piv rau cov nickel puag alloys. Muaj ntau yam khoom siv uas yuav tsum tau muaj 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, cov khoom siv hluav taws xob thiab cov khoom siv hauv qhov cub yog siv rau 253 MA.

Fabrication thiab Vuam nrog Stainless 253 MA

Stainless hlau 253 MA yog yooj yim fabricated los ntawm cov txheej txheem lag luam. Nyob rau hauv kev sib piv rau carbon steel, stainless hlau yog tougher thiab nyiam ua hauj lwm harden sai. Txawm li cas los xij, nrog cov khoom noj zoo thiab qeeb qeeb ua ke nrog cov kua dej ntau ntxiv, cov hlau no nyiam ua haujlwm hnyav tuaj yeem txo qis.

Stainless 253 MA tuaj yeem welded siv cov txheej txheem vuam. Filler hlau yuav tsum muaj qhov sib xws rau qhov siab tshaj plaws weld kev ncaj ncees thiab cov khoom.
