N07718执行标准是什么
N07718特征:
在酸和碱中具有良好的耐腐蚀性，在还原条件下有用。
出色的耐苛性碱直至熔融状态。
该材料在酸性、碱性和中性盐溶液中表现出良好的抵抗力，但在氧化盐溶液中会发生严重的腐蚀。
在室温和干燥和氯化氢中耐受所有干燥气体，可在高达 550C 的温度下使用。
对无机酸的抵抗力因温度和浓度以及溶液是否充气而异。在脱气酸中耐腐蚀性更好。
几乎不受 315C 以上颗粒间侵蚀的影响，氯酸盐必须保持在水平。
ASTM B 670 N07718在某些环境下更倾向于应力腐蚀开裂。已发现ASTM B 670 N07718可耐受酸性气体环境。ASTM B 670 N07718 合金在高速海水中的低腐蚀率和高强度相结合，特别适用于船舶服务中的离心泵轴。在停滞或缓慢移动的海水中，可能会发生污垢，随后会出现点蚀，但这种点蚀在经过相当快速的初始攻击后会减慢。
