1、主体材料选用应考虑的因素
从金相考虑，金属材料中除了具有面心立方品格的奥氏体钢、铜，铝等以外，一般的钢材在低温状态下会出现低温脆性，从而降低阀门的强度和使用寿命。选择主体材料时首先要选用适合于低温下工作的材料。铝在低温下不会出现低温脆性，但因铝及铝合金的硬度不高，铝密封面的耐磨、耐擦伤性能差，所以在低温阀门中的使用有一定的限制，仅在低压和小口径阀门中选用在低温工作的材料要保证其低温性能，主要是保证其冷冲击强度，阀内件必须通过正确选材，使其具有足够的冷冲击强度，才能防止断裂。C和Cr的合金钢在低于-20℃时候很快失去抗冲击强度，所以使用温度分别限制在-30℃和50℃，含N量为3.5%的镍钢可以使用到-100℃，含N量9%的保钢可以使用到-192℃。奥氏体不锈钢、，家乃尔合金，哈氏合金，钛铝合金及青铜可以使用到更低的温度(-273℃)
除此以外，低温阀门的材料选用还应考虑以下一些因素：
