Raws li qhov kev xav tau ntawm kev ua tau zoo sib txawv ntawmGB/T9711-2017Cov kav dej hlau, tempering tuaj yeem muab faib ua cov hom hauv qab no raws li qhov kub tempering:
1. Kub tsawg tempering (150-250 degrees)
Cov qauv tau los ntawm kev kub qis tempering yog tempered martensite. Nws lub hom phiaj yog kom txo qhov kev ntxhov siab sab hauv thiab brittleness ntawm cov hlau quenched thaum tswj qhov nyuaj siab thiab kev hnav tsis kam ntawm cov hlau quenched, yog li kom tsis txhob tawg lossis puas tsuaj ua ntej lub sijhawm siv. Nws yog siv rau ntau yam cuab yeej txiav cov pa roj carbon siab, cov cuab yeej ntsuas, GB / T9711 pipeline steel yeeb nkab, dov bearings thiab carburized qhov chaw, thiab lwm yam. Qhov nyuaj tom qab tempering feem ntau yog HRC58-64.
2. Kub nruab nrab tempering (250-500 degrees)
Cov qauv tau los ntawm qhov kub nruab nrab tempering yog tempered troostite. Nws lub hom phiaj yog kom tau txais lub zog siab, elastic txwv thiab siab toughness. Yog li ntawd, nws yog siv rau kev kho ntau yam GB / T9711 pipeline steel yeeb nkab thiab kub ua haujlwm pwm, thiab qhov nyuaj tom qab tempering feem ntau yog HRC35-50.
3. Kub siab tempering (500-650 degrees)
Cov qauv tau los ntawm kev kub siab tempering yog tempered troostite. Kev kho cua sov ua ke quenching thiab kub siab tempering feem ntau hu ua quenching thiab tempering kev kho mob, lub hom phiaj ntawm qhov no yog kom tau txais cov khoom siv kho tshuab nrog lub zog zoo, hardness, plasticity thiab toughness. Yog li ntawd, nws yog dav siv rau hauv cov khoom tseem ceeb ntawm lub tsheb, GB / T9711 pipeline steel kav, cov cuab yeej tshuab, thiab lwm yam, xws li txuas rods, bolts, iav thiab shafts. Qhov nyuaj tom qab tempering feem ntau yog HB200-330.
