Alloy 2205是一种含有22%铬的双相不锈钢,在固溶退火后供应。 作为一种双相不锈钢,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)达到了33-34。在几乎所有腐蚀性介质中,其耐点蚀和裂隙腐蚀的性能都要优于Alloy 316L或Alloy 317L。 得益于出色的耐腐蚀属性,它非常适用于含有氯化物和硫化氢的环境,包括从含硫井中开采油气,以及存在氯化物污染的精炼厂和加工溶液。
此外,它还具有良好的耐侵蚀疲劳属性,以及较奥氏体钢更低的热膨胀率和更高的热导率。 它的屈服强度大约是奥氏体不锈钢的两倍,因此设计人员能够减轻重量,让这种合金具有较Alloy 316L或Alloy 317L更大的成本竞争力。
