At The Metals Factory, stainless steel flanges cover a full range of pressure ratings of these specifications (150 – 2500 psi for ASME & PN6-PN400 for DIN/EN flanges). We also specialize in producing non-standard stainless steel flanges up to a diameter of 4500 mm. Our manufacturing process for stainless steel flanges includes an adequate heat treatment and the examination of chemical and mechanical properties. We have CNC machines as well as conventional lathe machines for machining and processing various types of stainless steel flanges. Stainless steel flanges are generally made from forged carbon, alloy and stainless steel bar stock. The raw materials used for manufacturing stainless steel flanges include raw round bar of diameter size 20~400mm OD or stainless steel billets for large size flanges.
