制盐设备用不锈钢及复合板的选材

Selection Of Stainless Steel And Its Clad Plate Used for Salt-Making Plant

00Cr18Ni5Mo3Si2(以下简称18-5)属铁素体(α)-奥氏体(γ)双相不锈钢,具有良好的耐Cl^-点蚀和应力腐蚀性能,18-5不锈钢复合板因其兼备优良的使用性能和较低的制造成本,在制盐领域不锈钢材料中,是理想的选择。本文就00Cr18Ni5Mo3Si2双相不锈钢及复合板的性能、特点以及在制盐领域的成功事例作一介绍。

OOCrl8Ni5Mo3Si2 (hereinafter referred to as 18-5 ), a kind of ferritic(α)-austenitic(γ)duplex stainless steel, has good properties of resisting pit corrosion by chloride ion and stress corrosion. 18-5 stainless steel clad plale has become an ideal choice among other kinds of stainless steel used in the field of salt-making industry just because of ils superior applied properties and lower manufacturing costs. This paper gives a brief introduction to the properties, charcteristics and some successful examples in salt - making industry for 18-5 duplex stainless steel and its clad plate.
