The resistance of Stainless Steel 316 Slip On Raised Flanges near the seashore will also be dependent on whether the stainless surface can be rinsed by rainfall, which will reduce the tendency for surface chlorides to concentrate by evaporation. Stainless Steel 316 Blind Raised Flanges gives higher machining rates and lower tool wear in many operations. The addition of molybdenum and slightly higher nickel content make SS 316 Weld Neck Flanges suitable for architectural applications in severe settings, from polluted marine environments to areas with sub-zero temperatures. For stress relieving, heat Stainless Steel 316 Socket Weld Flanges from 200 Degree C – 400 Degree C and then air cool. This is usually sufficient for identification differentiation and verification of SS 316 Threaded Flanges, where the 1542 Degree C includes a metal sample to be used as a testing reference. Stainless Steel 316 Lap Joint Flanges are well suited for fabricated or formed applications.
