　　ASTM A181/A181M-2014

　　中文名称：通用锻制碳素钢管的规格

　　英文名称：Standard Specification for Carbon Steel Forgings, for General-Purpose Piping

　　原文名称：Standard Specification for Carbon Steel Forgings, for General-Purpose Piping

　　范围：This specification covers the carbon steel forgings used for general-purpose piping. Two classes of material are covered, Classes 60 and 70, and classified according to their mechanical properties. Except for flanges of all types, up to and including NPS 4 may be machined from hot-rolled or forged bar. Elbows, return bends, tees, and header tees shall not be machined directly from bar stock. Forgings shall be protected against sudden or too rapid cooling from the rolling or forging while passing through critical range. Heat treatment is neither required nor prohibited, but when applied, it shall consist of tempering, annealing, normalizing, or normalizing and tempering. Heat analysis shall be made to determine the percentage of the following elements: carbon, manganese, phosphorus, silicon, and sulfur. The mechanical properties of the material shall conform to the required tensile properties: tensile strength, yield strength, elongation, and reduction of area.
