Product Information

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.

ASTM A403 Chemical Compositions (%)

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
