Annealing
Annealing rau ASTM AISI 420 wrought stainless hlau.
Subcritical annealing (pom zoo) kub rau AISI 420 stainless hlau: los ntawm 675-760 degree (1245-1400 degree F); Cua txias los ntawm qhov kub thiab txias, siv cov cua kub cua sov sab saud kom txo qis hardness. Qhov sib thooj Rockwell hardness yog 94-97 HRB.
Tag nrho annealing kub rau hom 420 steel: 830-885 degree (1525-1625 degree F), thiab tom qab ntawd tsau kom huv si, rauv txias rau 790 degree (1455 degree F), txuas ntxiv txias ntawm 15-25 degree / h (27-45 degree F / h) txog 595 degree (1100 degree F); Cua txias rau chav tsev kub. Qhov sib thooj Rockwell hardness yog 86-95 HRB.
Isothermal annealing kub rau AISI 420 qib stainless hlau: Kub rau 830-885 degree (1525-1625 degree F); khaws 2h ntawm 705 degree (1300 degree F), qhov sib thooj Rockwell hardness yog 95 HRB. (Preheat ntawm subcritical annealing kub yog qhov tseem ceeb heev.)
Hardening
Hardening rau 420 qib stainless hlau: Cua sov rau austenitizing kub 980-1065 degree (1800-1950 degree F), quenching nruab nrab yog cua los yog roj, yog hais tias lub thickness yog> 0.25 in. (6.4 mm), roj quenching yuav tsum tau siv. Tom qab quenching rau hauv chav tsev kub, kev kho mob khaub thuas tam sim no tau pom zoo thiab qhov kev pom zoo rau kev kho mob khaub thuas yog -75± 10 degree (-100± 20 degree F), uas tuaj yeem txo cov austenite thiab ua kom qhov siab tshaj plaws.
Tempering
AISI 420 steel (SS420) yog nkig heev nyob rau hauv cov kev mob uas tsuas yog hardened thiab feem ntau yuav tsum tau tempered kom ua tau zoo toughness.
Tempering kub rau 420 qib stainless hlau tom qab austenitizing: 205-370 degree (400-700 degree F). Lub zog tensile thiab Rockwell hardness yog 1550-1930 MPa (225-280 ksi) thiab 48-56 HRC.
Kev ntxhov siab
Yog tias SS420 quenched tsis npau taws tam sim ntawd, qhov kev ntxhov siab yuav tsum tau ua sai sai.
