Khoom Description

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.

Corrosion Resistance

Txawm hais tias tsis yog tsim los rau aqueous corrosion kuj, lub siab chromium thiab nitrogen cov ntsiab lus muab cov qib pitting tsis kam kwv yees li ntawm 316. 253MA txawm li cas los xij muaj cov ntsiab lus carbon siab yog li muaj kev cuam tshuam rau rhiab heev; qhov no yuav txo tau aqueous corrosion tsis kam tom qab kub kev pab cuam los yog fabrication.

Thaum tshav kub kub Resistance

Oxidation - zoo heev tiv taus huab cua, ntawm qhov kub txog li 1100 degree. Nyob rau hauv qhov kub kub, cov hlau sai sai tsim ib tug nyias, heev adherent thiab elastic oxide. Qhov no oxide muab kev tiv thaiv zoo txawm tias nyob rau hauv cov xwm txheej cyclic,
