420A stainless hlau channel khoom:
Corrosion tsis kam: 420A stainless hlau muaj nruab nrab corrosion kuj, zoo ib yam li lwm yam stainless hlau hauv 420 series. Nws tsis zoo li corrosion-resistant li austenitic stainless hlau tab sis muab kev tiv thaiv zoo rau corrosion hauv ntau qhov chaw.
Hardness: Nws tuaj yeem ua tiav qhov tawv ntawm ib puag ncig 48-52 HRC thaum kho kom sov. Cov ntsiab lus tsis tshua muaj carbon ua rau nws qhov qis qis dua piv rau cov pa roj carbon ntau dua nyob rau hauv 420 series.
Lub zog: 420A stainless hlau nthuav tawm zoo txhua yam muaj zog thiab nruab nrab toughness.
420A stainless hlau channel tshav kub kho:
420A stainless hlau yog feem ntau muab rau hauv cov mob annealed, uas txhim kho machinability thiab txo cov kev ntxhov siab sab hauv.
Nws tuaj yeem ua kom tawv tawv los ntawm kev kho cua sov, feem ntau yog cua sov mus rau ib puag ncig 950-1050 degree (1742-1922 degree F) thiab tom qab ntawd quenching hauv roj lossis cua. Cov txheej txheem no txhim kho nws cov hardness thiab lub zog rau ib qho twg.
Tempering yog ua tiav tom qab hardening ntawm qhov kub thiab txias li ntawm 150-350 degree (302-662 degree F) kom ua tiav qhov xav tau qhov sib npaug ntawm hardness thiab toughness.
