ASTM A403 WP304 Elbow Specifications

Standard Specification for Wrought Austenitic Stainless Steel Fittings

ASTM A403 WP304 covers the standard for wrought austenitic stainless steel fittings for pressure piping applications. The material of pipe fittings shall include forgings, bars, plates or seamless or welded pipes. Forging or forming operations shall be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or a combination of two or more of these operations. All accessories should be heat treated.

Chemical and product analysis should be performed and should meet the required chemical composition of carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum and titanium. Tensile tests should be performed on fitting materials to determine tensile properties such as yield strength and tensile strength. Accessories provided in accordance with this specification shall be visually inspected for surface discontinuities, surface inspections, and mechanical markings.

Butt welded pipe fittings are designed to be field welded at their ends to join pipes together and allow for changes in direction or pipe diameter, or branching or ending.

The accessory then becomes part of the system for transporting fluids (oil, gas, steam, chemicals…) over short or long distances in a e and efficient manner.
Other types of fittings can be threaded or socket welded.

This specification covers several grades of austenitic stainless steel alloys. Designate grades with prefixes according to applicable ASTM/ASME or MSS standards. For each WP stainless grade, several types of fittings are specified to indicate whether seamless or welded construction is used. Category names are also used to indicate NDT methods and NDT scopes. Below is a general summary of the fitting grades available for all WP stainless grades.

Fitting Classes for WP Grades

CR Corrosion resistant grade. S through WU Classes do not apply.
WP-S Seamless
WP-W Welded, RT or UT all pipe starting material welds made with filler metal. All fitting manufacturer welds except as excluded in A/SA403 paragraph 5.4.3.
If UT is substituted for RT, all welds must be examined 100% for their length as required by A/SA403 paragraph 5.6
WP-WX RT all welds with or without filler metal.
WP-WU UT all welds with or without filler metal.
WPgrade-grade-class Insert grades (304-304L) and class (S,W,WX, or WU). Applies to fittings meeting all chemical and physical requirements of both grades.
