654SMo (S32654, 1.4652) Super austenitic stainless steel overview:

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 equivalent to the best nickel-based alloys because of its nitrogen content. It is twice as high as 254SMO, and its intensity is higher than 904L and 254SMO.

654SMO (S32654, 1.4652) super austenitic stainless steel smelting method, currently popular abroad argon-oxygen decarburization refining method (VOD or AOD), can also be used to produce stainless steel continuous casting method. But because the amount of 654SMO steel is much smaller than that of ordinary austenitic stainless steel, it is smelted by AOD or VOD refining furnace (usually a furnace requires more than 20T), and the supplier is not willing to press the inventory, so our company uses vacuum induction refining furnace. Steel, plus electroslag remelting and refining, and then forging open billets, processing round steel, forgings, flanges, etc.

654SMO (S32654, 1.4652) Super austenitic stainless steel because it contains high molybdenum, in the processing of seamless pipe perforation, the steel is hard and sticky, it is easy to eccentric or puncture, there is a great risk in perforation, Our company uses round steel to punch holes, and directly rolls to the cold rolling or cold drawing of the rolling mill. Although the cost has been 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 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 or corrosion resistance, it has more excellent high temperature or corrosion resistance than 904L and 254SMO.
