1.1 This specification covers a group of common requirements that shall apply to wrought steel piping fittings covered in any of the following individual product specifications or any other ASTM specification that invokes this specification or portions thereof:

Title of SpecificationASTM
Designation
Specification for Piping Fittings of Wrought
Carbon Steel and Alloy Steel for Moderate and
Elevated Temperatures
A 234/A 234M
Specification for Wrought Austenitic Stainless
Steel Piping Fittings
A 403/A 403M
Specification for Piping Fittings of Wrought Carbon
Steel and Alloy Steel for Low-Temperature Service
A 420/A 420M
Specification for Butt-Welding, Wrought-Carbon
Steel, Piping Fittings with Improved Notch Toughness
A 758/A 758M
Specification for As-Welded Wrought Austenitic
Stainless Steel Fittings for General Corrosive
Service at Low and Moderate Temperatures
A 774/A 774M
Specification for Wrought Ferritic, Ferritic/Austenitic,
and Martensitic Stainless Steel Piping Fittings
A 815/A 815M
Specification for Heat-Treated Carbon Steel
Fittings for Low-Temperature and Corrosive Service
A 858/A 858M
Specification for Wrought High-Strength
Low-Alloy Steel Butt-Welded Fittings
A 860/A 860M

1.2 In case of conflict between a requirement of the individual product specification and a requirement of this general requirement specification, the requirements of the individual product specification shall prevail over those of this specification.

1.3 By mutual agreement between the purchaser and the supplier, additional requirements may be specified (See 4.1.7). The acceptance of any such additional requirements shall be dependent on negotiations with the supplier and must be included in the order as agreed upon by the purchaser and supplier.

1.4 The values stated in either inch-pound units or SI units [metric] are to be regarded separately as standard. Within the text and the tables, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the M designation [SI] of the product specification is specified in the order.


This specification covers the common requirements that shall apply to wrought steel piping fittings. The material shall consist of forgings, bars, plates, and seamless or welded tubular products. Ferritic steels shall be fully killed. Hollow cylindrically shaped parts up to and including NPS 4 may be machined from bar or seamless tubular material. Elbows, return bends, tees, and header tees shall not be machined directly from bar stock. The following procedures shall be done for heat treatment: full annealing, solution annealing, isothermal annealing, normalizing, tempering and post-weld heat treatment, stress relieving, and quench and temper. Chemical analysis, heat analysis, and product analysis shall also be done. The chemical requirements shall conform to the required compositions of carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, vanadium, columbium, titanium, aluminum, lead, and copper. The following tests shall be done for the mechanical requirements: tension, hardness, impact, and hydrostatic tests.
