321 stainless steel seamless pipe Polishing

Reliant Pipes can polish nearly any stainless steel pipe item to a #4 polish, #6 Polish, #7 polish or a #8 mirror finish. Stainless steel polished pipes can also be cut to size.
321 stainless steel seamless pipe Beveling Reliant Pipes can bevel stainless steel pipe to prepare for welding or other processes.
321 stainless steel seamless pipe Honing/Turning Reliant Pipes can hone pipe and tube, using a precision abrasion process in order to obtain a desired finish or close dimensional tolerance.
321 stainless steel seamless pipe Heatreating & Annealing Some grades of stainless steel pipe and tube can be heatreated to change the mechanical properties. Precipitation Hardening Stainless Steels such as 17-4PH can be heatreated. 410 stainless steel plate can also be heatreated. In some cases, secondary annealing 300 series stainless steel may be required depending on the application
321 stainless steel seamless pipe Positive Material Identification (PMI) Reliant Pipes can perform PMI testing in house for most stainless steel grades, or we can work with independent labs to complete PMI in order to meet customer specifications.
321 stainless steel seamless pipe UT Testing In some cases, UT testing of the stainless steel pipe and tueb may be required. We can assist you with this requirement.

Difference Between Inconel and Stainless Steel

Inconel

Inconel, a product of Special Metals Corp., has a nickel, chromium and molybdenum composition. Inconel is resistant to corrosion and pitting and comes in several different alloys. Stainless steel is composed of carbon, manganese, phosphorus, sulfur, silicone, chromium and nickel. Both Inconel and stainless steel use a numbering system for different alloys and strengths. These products have silver finishes, but different textures create matte or shiny surfaces.

Cost or Price Difference between Inconel & stainless steel

Inconel is more expensive than stainless steel. For example, exhaust valves for fast cars cost $150 more than stainless, at the time of publication. Special Metals Corp., the inventor of Inconel, sells this alloy in flat sheets, pipes, tubes, flat bars, wire and other shapes. Special Metals shows production of 25 qualities of Inconel. Each product has different characteristics and a different price.
