S32900 stainless steel black / bright bar wholesales for industry
1 . Descriptions:
SS 329 round bar ,which is an age hardening nickel base super – alloy with exceptional strength from room temperature through about 1600 Degree F. Limit currents and the size of the fusion zone, where rapid cooling in Stainless Steel 329 Square Bars from welding is necessary to minimize aging stresses. After welding, the fabrication of Stainless Steel 329 Flat Bars should be solution treated, using rapid heating and cooling rates through the aging range. GTAW using DC straight polarity in Stainless Steel 329 Threaded Bars requires good joint fit – up and cooling by means of copper backup bars or water – cooled fixtures. After welding, the assembly of Stainless Steel 329 Hollow Bars should be solution treated using rapid heating and cooling rates through the 1200 Degree F – 1600 Degree F range, followed by aging. Stainless Steel 329 Hexagonal Bars can even be a substitute of Austenitic grade of marine surrounding, where we offer tailor made these with suitable wedge options. Stainless Steel 329 Triangular Bars doesn’t losses it shape when exhibit to a temperature of liquid nitrogen which is also high appreciable and has a great commercial demand. High strength condition: Solution treatment of Stainless Steel 329 Bars is up to 60 Degree F – 100 Degree F below the beta (typically 1460 Degree F – 1480 Degree F), not less than 30 minutes, and then water quench.
