摘要
钢中气体氢对钢的性能产生有害影响,所以必须尽量去除。氢在取样制样、保存过程中极易损失和污染,所以要保证低温避免氢损。
Hydrogen gas in steel harmfully affects on the performance of the steel, so we have to remove Hydrogen. Gas loss and pollution happen easily in the process of taking sample, preparation, and preservation, so to ensure the low temperature to avoid hydrogen damage.
