Txais tos rau kev lag luam wholesale customized astm 20cr alloy steel phaj hlau ntawm tus nqi sib tw los ntawm peb lub hoobkas. Cov kev pabcuam zoo thiab cov khoom zoo yog muaj.
Khoom Description
Piv nrog 15Cr steel, 20Cr steel muaj zog dua thiab hardenability, thiab qhov tseem ceeb quenching txoj kab uas hla ntawm cov roj mus txog 4 ~ 22 hli, thiab qhov tseem ceeb quenching txoj kab uas hla hauv dej mus txog 11 ~ 40 hli, tab sis lub toughness yog tsis zoo. Cov hlau tseem muaj qhov nyiam ntawm cov qoob loo loj hlob thaum carburizing, thiab ncaj qha quenching ntawm qhov txias muaj qhov cuam tshuam zoo rau qhov cuam tshuam toughness, yog li cov quenching theem nrab yuav tsum tau tom qab carburizing los txhim kho lub toughness ntawm cov tub ntxhais qhov chaw tsis tempering brittleness.
