SS 420 yog ib qho martensitic thiab hardness stainless hlau uas yog avarianation ntawm alloy 410.Txawm hais tias nws yog imaginable vim nws congealed zog, nws yog tsis welded tsis tu ncua. SS 420 Coils feem ntau yog siv rau hauv kev lag luam ntawm kev tsim tsheb los muab lub zog thiab ua haujlwm ntev uas tseem ceeb kom tau txais los ntawm kev sim hauv kev sib tsoo. Vim nws cov khoom tiv thaiv corrosion thiab tsis tshua muaj txij nkawm, ntau lub lag luam xws li tshuaj lom neeg thiab petrochemical nroj tsuag, kev lag luam kws tshuaj thiab tshuaj tankers kuj nyiam SS 420 Steel.

Vim nws hardenability, cov chav kawm martensitic ntawm coils muaj tsawg weldability. Kev txiav txim siab tshwj xeeb yog yuav tsum tau tiv thaiv kom tsis txhob txias tawg los ntawm preheating txog 550 deg f. Tom qab weld kev kho cua sov yuav tsum xav txog kev ua tiav cov khoom xav tau. Qhov sib txawv loj yog nws cov ntsiab lus carbon uas yuav tsum tau kho tom qab vuam cua sov thiab preheats kev kho mob. Nws raug pom zoo rau qhov softness thiab rhuab uniformly txog 1500 deg f rau 1650 deg f. Tom qab hardening nws yog sai txias thiab soaks ntawm kub. Kev ua haujlwm txo kev ntxhov siab kuj ua tau.
