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 Pipe Fitting Elbow Standard Scope
The standard includes several grades of austenitic stainless steel alloys, and uses the WP or CR prefix to mark the grade of steel, depending on the applicable ASTM or MSS size and rated pressure standards.
ASTM A403 is designed for forged steel pipe fittings, Cast pipe fittings are not suitable. (Austenitic stainless steel castings are included in these standard, A351/A351M, A743/A743M and A744/A744M.)
Material under this standard named as WP Grade, and for each WP grade stainless steel, several categories of pipe fittings are included, to indicate that a seamless or welded structure is used. Class designations are also used to indicate non-destructive testing methods and the extent of non-destructive testing (NDE).
This standard and applicable material standards are described in both inch-pound units and SI units. However, unless the "M" standard number is specified in the order, the material is supplied in inch-pound units.
Values expressed in either inches-pounds or SI units should be considered standard values. In the text, SI units are shown in brackets. Since the values in the two unit systems are unlikely to be exactly equal, it is necessary to independently adopt two unit systems. If mixed, it will lead to inconsistency with this standard.
