Standards & Materials: ASTM A403
ASTM A403 Stainless Steel Pipe Fittings refers to the material of forged and rolled austenitic stainless fittings for pressure pipes. Common grades are WP304/L, WP316/L. They can be used into many fields as engineering industry, energy conversion plants etc.
The ASTM A403 Stainless Steel Threaded Coupling offers several advantages. It allows for easy installation and disassembly without requiring specialized tools or welding. The threaded connection provides a reliable and leak-free joint, suitable for both low and high-pressure applications. Additionally, the stainless steel construction ensures resistance to corrosion and other harsh environmental factors, making it suitable for demanding operating conditions.
Note:
Where a ellipsis(﹍)appears in the table, there is no requirement and the element need to be analyzed for or reported
The method of analysis for nitrogen shall be a matter of agreement between the purchaser and manufacturer
Columbium 0.10-0.30%; Vanadium 0.10-0.30%.
For small diameter or thin walls, or both, where many drawing passes are required, a carbon maximum of 0.04% is necessary in grades TP304L and TP316L. Small outside diameter tubes are defined as those less than 0.500in.(23.7mm) in outside diameter and light wall tubes as those less than 0.049in.(1.24mm) in average wall thickness
