Khoom Taw qhia

Khoom Description

40NiCrMo7 Forged steel bar muaj lub zog siab, toughness, zoo heev hardenability thiab stability tiv thaiv overheating, tab sis siab dawb qhov chaw rhiab heev thiab temper brittleness. Weldability tsis zoo, kub preheating yuav tsum tau ua ntej vuam, kev ntxhov siab yuav tsum tau tom qab vuam, thiab nws yuav siv tau tom qab tempering.
