Gautam Tubes is the leading manufacturer, supplier and stockiest of the commendable quality of ASTM A403 WP321H Buttweld fittings. These fittings are offered to the clients at custom-made specifications as per the demands made by the esteem patrons. It is offered to the clients at various specifications that vary in standards, dimensions, sizes, types, bending radius, wall thickness, etc. The product is globally appreciated and used in many industrial applications due to many good features found in it. ASTM A403, a standard specification is covering the standard for the wrought stainless steel fitting for the applications like pressure piping.
The material for the fitting is consisting of the plates, bars, seamless/welded tubular products. The sharpening and forging operation will be done by extruding, hammering, piercing, upsetting, bending, fusion welding and also a combination of these as well. All the fittings will be undergoing the heat treatment addition to product and chemical analysis will be done and will conform to the needed chemical composition in phosphorous, sulfur, silicon, manganese, titanium, chromium, etc.
Tension will also be done on the fitting material for determining the tensile properties like tensile strength and yielding strength. Fitting that is supplied under these specifications will be thoroughly examined visually for the surface checks, surface discontinuities, and mechanical marks. Alloy stainless steel 321H or UNS S 32109 stainless steel is the greater carbon version of SS 321 alloy, contented with carbon at 0.04 to 0.10. The alloy is developed to enhance the high strength at the temperature more than 537 Deg C. In many cases the carbon content enables double certifications.
