　　原文名稱：Standard Specification for Forged or Rolled 8 and 9% Nickel Alloy Steel Flanges, Fittings, Valves, and Parts for Low-Temperature Service

　　范圍：This specification covers the 8 and 9% nickel-alloy steel forged or rolled flanges, fittings, valves, and parts intended for use in welded pressure vessels for low-temperature service. Two types of materials are specified according to the chemical composition: type I and type II. Materials for forgings shall consist of ingots, or either forged or rolled blooms, billets, or bars. Except for all types of flanges, elbows, return bends, tees, and header tees, other parts including NPS 4 may be machined from hot-rolled or forged bar. The steel shall conform to the specified chemical requirements for carbon, manganese, phosphorus, sulfur, silicon, and nickel. The following methods of heat treatment shall be used: quenched and tempered and double normalized and tempered. Two tests shall be done to meet the mechanical requirements of the material: tension test and Charpy impact test.
