一段话-3？ 3. hot pressed carbon or low alloy steel heads must be normalized subsequent to the pressing operation unless the manufacturer can prove that the temperature control during and following forming is such that the finished heads are in a metallurgical condition equivalent to that from a normalizing procedure. 热压成型的碳钢和低合金钢封头 必须做正火处理，随后进行压形操作 ，除非厂商可以证明在在压形过程中和随后成型的温度，能够让成型后的封头达到金属冶炼（预热）温度，那么就可以不用进行正火处理 .（这个问题我想向大家请教下，最后用紫色写的，大家可以一起讨论下). 4. all cold formed 304l stainless steel heads shall be solution annealed if the strain induced exceeds 20% as defined by the design code . 如果应变力 超过设计规范的 20% ， 所有 304l 不锈钢冷成型封头应进行固溶退火处理 . 不懂专业，在学习本帖的过程中发现有几处翻译值得商榷。 举两例： 3. subsequent to prep. at a later time than; after. 在...之后， hot pressed carbon or low alloy steel heads must be normalized subsequent to the pressing operation 热压成型的碳钢和低合金钢封头 必须在压形操作之后进行正火处理，.... 4. exceeds 20% as defined by the design code. ...按照设计规范之定义超过20%. --------------------------fyi 查看更多
