420 Stainless hlau
GNEE steel tam sim no suav nrog Alloy 420 (UNS S42000) hauv cov ntawv, ntawv coil, phaj, puag ncig bar, txheej txheem ca bar thiab tubular khoom.
Cov yam ntxwv ntawm 420 Stainless
Kev kho cua sov
Annealing - Qib 420 stainless hlau tuaj yeem ua kom sov ntawm qhov kub ntawm 840 txog 900 degree, ua raws li lub cub tawg qeeb ntawm 600 degree thiab tom qab ntawd cua txias.
Txheej Txheem Anneal - Qib 420 tuaj yeem ua rau ntawm 735 txog 785 degree thiab cua txias.
Hardening - Cov txheej txheem no suav nrog cov cua sov qib 420 steels ntawm 980 txog 1035 degree, ua raws li huab cua lossis roj quenching. Roj quenching feem ntau yog nyiam rau cov hlau hnyav. Tempering yog ua ntawm 150 mus rau 370 degree kom ua tiav siab hardness thiab zoo mechanical zog. Qib 420 yuav tsum tsis txhob tempered ntawm 425 thiab 600 degree

Corrosion
420 muab tag nrho corrosion kuj tsuas yog nyob rau hauv lub hardened los yog hardened thiab kev nyuaj siab relieved tej yam kev mob. Nyob rau hauv cov xwm txheej no, nws cov corrosion kuj zoo ib yam li Hom 410. Hom 420 resists corrosion los ntawm huab cua, dej tshiab, kuv cov dej, chav, carbonic acid, roj crude, roj av, hws, cawv, ammonia, mercury, sterilizing daws, xab npum thiab lwm yam corrosive media.
