What is the difference between UNS S32750 and S32760?
S32760 超级双相不锈钢
While involving extended exposure to temperatures more than 572F use of S32760 is not recommended. The chemical composition of S32750 and S32760 are similar; however， the latter contains slightly more copper and tungsten.
应用
双相不锈钢是一种耐腐蚀性极强的可加工硬化合金。它们的微观结构由奥氏体相和铁素体相混合组成。因此，双相不锈钢同时具有奥氏体不锈钢和铁素体不锈钢的特性。与纯奥氏体不锈钢和纯铁素体不锈钢相比，这种特性组合可能意味着一些折衷。
- 双相不锈钢通常用于：
- 化学加工、运输和储存
- 石油和天然气勘探及海上钻机
- 石油和天然气提炼
- 海洋环境
- 污染控制设备
- 纸浆和纸张制造
- 化学加工厂
