Alloy 400是一种镍铜单相合金,最常在热加工和退火后供应。 虽然此钢种能够通过回火或冷加工来增强其属性,但在标准退火条件下,它很容易成形和装配,而无需通过额外的热处理来恢复合金的平衡。 它在温度零下时仍具有出色的机械属性。 虽然延性和耐冲击性略有下降,但强度和硬度得以了提高。
Alloy 400对许多还原介质都具有出色的耐腐蚀性。 它可用在与氟、氢氟酸、氟化氢或其衍生物接触的环境中 – 实践证明,它能经受住所有浓度及高达沸点的氢氟酸。 它还能在还原条件下耐受许多形态的硫酸和盐酸,并在海水中有良好的表现。 Alloy 400能够在大多数淡水和工业用水中防应力腐蚀开裂和点蚀。 因此,它被广泛用于海洋工程、化学和烃加工设备、阀门、泵、轴、接头、紧固件和换热器。
