Alloy 32750是一种超级双相不锈钢,在热加工和固溶退火后供应。 作为一种超级双相不锈钢,它兼具奥氏体和铁素体钢种的优势属性。 更高的铬、钼和氮含量使得其抗点蚀当量值(PREN)超过了40。在几乎所有腐蚀性介质中,它的抗点蚀和裂隙腐蚀性能都要优于奥氏体和双相不锈钢,同时其临界点蚀温度超过了50°C。
在退火后供应,它的屈服强度达到80ksi (550Mpa),优于大多数的奥氏体和双相不锈钢种。 它无法通过热处理来硬化,但可通过冷加工来强化。 它还具有较低的热膨胀系数,热导率高于奥氏体钢,适合的工作温度最高达300°C。Alloy 32750被NACE MR 0175列为适用于酸性环境的材料,经ASME批准可用于压力容器应用,用途广泛。
