• A篇铁基材料标准 • ASME材料种类太多,这里仅仅结合压水堆
反应堆主要设备常用材料进行分析和比较。 • 1. SA-508标准“压力容器用经真空处理的淬
火加回火碳钢和合金钢锻件” • 使用上述标准材料的有反应堆压力容器、蒸
汽发生器等,选用其中3级1类钢种。材料属 于锰镍钼合金钢。
2.材料的化学成分
其它材料
• Non-structural attachments, such as insulation supports, name-plates, and temporary attachments, if required, may be noncertified material.
• Non-pressure retaining material, such as cooling shroud support, alignment pin, stud bolt elongation measuring rods and tools, if any, may be of ASME or other Standards .
