40Cr Alloy Seamless Steel yeeb nkab
Lus piav qhia luv luv:
40Cr steel yeeb nkab yog ib yam ntawm Suav GB txheem alloy steel rau engineering thiab machinery lub hom phiaj, thiab ib tug ntawm cov feem ntau lug siv steel qib.
Tom qab quenching thiab tempering kev kho mob, 40Cr steel yeeb nkab muaj cov cuab yeej zoo txhua yam, tsis tshua muaj kev kub ntxhov, tsis tshua muaj siab rhiab heev, zoo hardenability, thiab siab qaug zog hauv cov roj txias.Thaum cov dej txias, cov duab nyuaj ntawm cov khoom yog qhov ua rau tawg, qhov txias bending plasticity yog nruab nrab, thiab kev txiav ua haujlwm tom qab normalizing yog zoo, tab sis cov weldability tsis zoo, yuav tsum tau preheated ua ntej vuam, thiab feem ntau yog siv nyob rau hauv lub xeev. ntawm quenching thiab tempering.
