Kev kho cua sov

Kev daws Annealing:Haum rau ob lub phaj thiab bar. Kub cov khoom rau 1020-1065℃(1870-1950℃F) thiab cua txias. Cov txheej txheem no dissolves alloying ntsiab thiab homogenizes tus qauv.

Cov nag lossis daus Hardeningyog cov txheej txheem kev kho cua sov tshaj plaws rau 17-4PH thiab ua kom muaj zog thiab hardness.

H900: Haum rau bar, tab sis tsis pom zoo rau phaj. Kub cov khoom rau 482℃(900℃F) rau 1 teev thiab cua txias.

H925: Haum rau ob lub phaj thiab bar. Kub rau 496℃(925℃F) rau 1 teev thiab cua txias.

H1025: Haum rau ob lub phaj thiab bar. Kub rau 552℃(1025℃F) rau 1 teev thiab cua txias.

H1075: Haum rau phaj thiab bar. Kub rau 579℃(1075℃F) rau 1 teev, ces cua txias.

H1150: Haum rau phaj thiab bar. Tshav kub rau 621℃(1150℃F) rau 4 teev, txias rau chav sov, rov ua kom sov rau 621℃rau 4 teev, ces cua txias.

H1150M: Haum rau phaj thiab bar. Tshav kub rau 621℃(1150℃F) rau 4 teev, txias rau hauv chav tsev kub, ces rov qab rau 760℃(1400℃F) rau 2 teev, ces cua txias.

H1150D: Haum rau bar, tab sis tsis siv ntau zaus rau phaj. Ib yam li H1150M, tab sis nrog rau kev tswj hwm kev laus thib ob.

Kev ntxhov siab:Haum rau phaj thiab bar. Thaum tshav kub kub rau kwv yees li 290-425℃(550-800℃F) thiab tuav 1-2 teev kom txo tau cov kev ntxhov siab sab hauv yam tsis muaj kev hloov pauv ntau yam khoom siv.

Annealing:17-4PH feem ntau tsis yog tag nrho annealed vim qhov no yuav tshem tawm cov txiaj ntsig ntawm nws cov nag lossis daus hardening.
