SUS630 Stainless hlau: nag lossis daus -Hardening Strength

Qib 630 martensitic nag lossis daus hardening stainless hlau muaj kev sib xyaw ua haujlwm siab thiab lub zog tom qab kev kho cua sov tsim nyog. Nws kuj muaj qhov zoo sib xws corrosion thiab kub tsis kam rau qib 304. Cov ntsiab lus "Hom 630" thiab "17-4PH" hais txog tib qib.

 

Thaum tshav kub kub Resistance Qib no muaj qhov zoo oxidation tsis kam, tab sis kom tsis txhob txo nws cov khoom thiab hardness nws yuav tsum tsis txhob siv siab tshaj nws lub hnub nyoog hardening kub. Kev nthuav dav ntev dua nyob rau hauv thaj tsam 370-480 ° C yuav tsum zam yog tias qhov kub thiab txias yog qhov tseem ceeb. Kev kho cua sov Kev Kho Mob Kev Kho Mob (Kev Kho A) Kub ntawm 1040 ° C rau ½ teev thiab txias rau 30 ° C siab tshaj plaws hauv huab cua. Roj quenching tuaj yeem siv rau cov ntu me me uas tsis muaj qhov sib txawv.
