S32652(UNS 654SMO)Super Austenitic Stainless Steel pipe 1.4652 / X1CrNiMOCUN24-22-8

ASTM A312, ASTM A269 , S32652 UNS 654SMO 1.4652 X1CrNiMOCUN24-22-8   Super Austenitic Stainless Steel Pipe and Tube

Material Description:

654SMo (S32654, 1.4652) super austenitic stainless steel is a super austenitic stainless steel containing 23% nickel, 25% chromium and 7% molybdenum, its corrosion resistance is much better than ordinary austenitic steel.

654SMo (S32654, 1.4652) super austenitic stainless steel contains high molybdenum. When processing seamless pipe perforations, the steel type is hard and sticky, and it is easy to eccentric or crack. There is a great risk in perforation. The round steel center is perforated and then pierced, and the rolling mill is cold rolled or cold drawn. Although the cost is increased, it can guarantee a high success rate.

654SMo (S32654, 1.4652) super austenitic stainless steel has very good local corrosion resistance. It has good pitting corrosion resistance and good stress corrosion resistance under seawater, aeration, gaps, and low-speed erosion conditions. Alternative materials for nickel-based alloys and titanium alloys. Secondly, in terms of high temperature resistance or corrosion resistance, it has more excellent high temperature resistance or corrosion resistance than 904L and 254SMO.
