Stainless hlau muaj forging zog zoo ib yam li carbon steel thiab tsawg alloy hlau. Nws tuaj yeem tsim los ntawm kev sib txawv forging ntawm cov khoom sib txawv forging. Qhov sib txawv tsuas yog tias ntawm forging kub, stainless steels muaj zog txaus siab dua carbon thiab tsawg alloy steels; thib ob, qee cov hlau tsis muaj steel, xws li austenitic-ferritic duplex stainless hlau thiab martensitic stainless hlau, yog rhuab rau forging Thaum kub, muaj ib theem thib ob - (δ) ferrite nyob rau hauv ciam teb. Vim tias nws cov khoom sib txawv thiab cov txheej txheem recrystallization los ntawm r-theem ntawm matrix, plasticity ntawm stainless hlau tau txo qis heev.
Vim qhov nqaim forging kub ntau yam ntawm stainless hlau thiab qis pib forging kub, piv txwv li, qhov siab tshaj plaws forging kub ntawm high-chromium martensitic stainless hlau yog 55-165 degree qis dua li ntawm cov hlau tsis tshua muaj hlau, yog li loj dua. forging load yuav tsum, piv nrog 40CrNiMo steel. , nrog kev nce ntawm cov ntsiab lus chromium, forging load ntawm martensitic stainless hlau nce 20 feem pua rau 100 feem pua ; Lub zog xav tau rau forging nag lossis daus hardening stainless hlau yog 30 feem pua rau 50 feem pua siab dua forging 40CrNiMo steel. Qhov nruab nrab chav tsev ntws kev ntxhov siab ntawm austenitic stainless hlau 0Cr18Ni9 ntawm qhov sib txawv ntawm qhov kev ntxhov siab yog piv nrog qhov nruab nrab chav ntsuas kev ntxhov siab ntawm 20 steel. Daim duab 3 qhia qhov nruab nrab chav tsev ntws kev ntxhov siab ntawm ob lub hlau no ntawm qhov kub sib txawv. Nws tuaj yeem pom los ntawm daim duab uas nyob ntawm 982 degree (1800F) thiab ib qho degree ntawm deformation ntau dua 6 feem pua, qhov nruab nrab chav tsev txaus siab ntawm forged 0Cr18Ni9 stainless hlau yog tsawg kawg yog ob zaug ntawm 20 steel.
