在化工,炼油等机械制造厂中常常会遇到一些耐酸不锈钢的焊接。常用的不锈钢板是0 Cr 18 Ni 9 Ti型,但根据工作介质的不同,在某些容器及管子的材质选择上要求比0 Cr 18 Ni 9 Ti不锈钢具有更高的抗晶间腐蚀性能。众所周知,00 Cr 18Ni 12 Mo 2Ti不锈钢的抗晶间腐蚀能力相当优越,它是在0 Cr 18 Ni 9 Ti基础上适当提高铬、镍含量,并加入2～3％的钼,藉
In chemical, oil refining and other machinery manufacturers often encounter some acid-resistant stainless steel welding. Commonly used stainless steel plate is 0 Cr 18 Ni 9 Ti type, but depending on the working medium, in some container and pipe material selection than 0 Cr 18 Ni 9 Ti stainless steel with higher resistance to intergranular corrosion. As we all know, 00 Cr 18Ni 12 Mo 2Ti stainless steel has very good resistance to intergranular corrosion, which is based on the 0 Cr 18 Ni 9 Ti based on the appropriate increase in chromium and nickel content, and by adding 2 to 3% molybdenum, by
