Txoj kev tsim khoom
DIN 17175 St45.8 seamless steel kav yuav ua tau los ntawm kub dov, txias dov, kub nias, kub kos duab los yog txias kos duab.
Cov kav hlau tuaj yeem raug smelted nyob rau hauv ib qho qhib hearth los yog hluav taws xob rauv raws li txoj kev oxygen tshuab, thiab tag nrho cov hlau yuav tsum tau cam khwb cia statically.
Muaj
17175 St45.8 seamless steel yeeb nkab yuav raug xa nrog kev kho cua sov kom zoo.Kev kho cua sov muaj xws li:
- Normalization.
- Annealing.
- Tempering;los ntawm quenching kub, nws tsis txias, tab sis tempered.
- Kho huab hwm coj los ntawm isothermal transformation method.
