PH13-8Mo Stainless hlau
PH{{0}}Mo stainless hlau yog cov khoom siv ua haujlwm siab uas yog martensitic nag lossis daus-hardening stainless hlau nrog li ntawm 12-14 feem pua chromium, 7-8 feem pua npib tsib xee, 2-3 feem pua molybdenum, thiab 0.9-1.35 feem pua txhuas. Nws muaj lub zog siab, zoo heev tawg toughness, zoo transverse mechanical zog, thiab kev ntxhov siab corrosion kuj nyob rau hauv marine ib puag ncig, ua rau nws haum rau ntau yam kev siv uas muaj kev ua tau zoo thiab kev ntseeg siab yog qhov tseem ceeb.
PH13-8Mo stainless hlau muaj cov khoom siv zoo dua li lwm cov hlau alloys thiab yog qhov zoo tagnrho rau cov mob hnyav. Feem ntau, corrosion kuj ntawm PH13-8Mo steel yog superior rau 1Cr13 thiab 1Cr17Ni2 (431) martensitic stainless hlau; pitting corrosion kuj zoo dua li ntawm 17-4 thiab 15-5 steels vim qhov sib ntxiv ntawm molybdenum. Nws muaj qhov zoo tshaj plaws corrosion kuj nyob rau hauv lub siab hardened theem, raws li ua lwm yam los nag-hardening stainless hlau. Txawm hais tias PH13-8Mo steel yog me ntsis rhiab heev rau hydrogen embrittlement thaum muaj hnub nyoog ntawm kub qis dua 565 degree nyob rau hauv cov kev sim hnyav, hydrogen embrittlement fractures tsis tshua muaj tshwm sim hauv kev siv tswv yim. Kub siab tshaj 595 degree tiv thaiv hydrogen-induced cracking. Tsis tas li ntawd, cov hlau no muaj qhov ua tau zoo tshaj plaws rau sulfide kev ntxhov siab corrosion tawg thaum muaj hnub nyoog ntawm lossis siab dua 595 degree.

Corrosion Resistance ntawm PH13-8Mo Stainless Hlau
Kev tiv thaiv corrosion ntawm PH13-8Mo stainless hlau H950 temper rau 5 feem pua cov tshuaj ntsev yog piv rau 304 stainless hlau. Kev tiv thaiv corrosion ntawm PH13-8Mo stainless hlau nyob rau hauv muaj zog oxidizing thiab txo cov kua qaub yog piv rau 304 stainless hlau. PH13-8Mo stainless hlau, zoo li lwm cov nag lossis daus-hardening stainless hlau, muaj qhov zoo tshaj plaws corrosion kuj thaum tag nrho hardened, thiab qhov kub thiab txias dua, qhov corrosion kuj zoo dua.
Nyob rau hauv cov dej hiav txwv, cov forged thiab welded xeev ntawm PH13-8Mo stainless hlau pom zoo tiv thaiv kev ntxhov siab corrosion cracking. Qhov tsawg kawg nkaus kev laus kub rau kev pom kev ntxhov siab corrosion cracking kuj yog 538 degree.
Kub tsim ntawm PH13-8Mo Stainless hlau
1170-1205 degree yog qhov zoo tshaj plaws forging kub ntau rau PH13-8Mo stainless hlau. Lub deformation ntawm ntau tshaj 50 feem pua hauv qab 1040 degree yog yuav tsum tau los tsim ib tug refined grain qauv.
