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 .

研究结果表明，对30crmnsia电镀样品材料氢脆敏感性的影响因素依次为：组织结构、除氢状态、电流密度、去应力状态、酸洗状态。
