The manufacturer shall specify possibility of embrittlement versus temperature in service .
制造商应该对使用过程中温度引起脆化的可能性进行说明。
However , embrittlement occurs in some metals at elevated temperatures and pressures .
但是，当温度和压力升高时，某些金属会脆化。
The results indicate that the influencing factors on hydrogen embrittlement sensitivity of 30crmnsia plated were structure , dehydrogenation , current density , distressing and pickling sequentially .
