　　英文名稱：Standard Specification for Steel Rivets and Bars for Rivets, Pressure Vessels

　　原文名稱：Standard Specification for Steel Rivets and Bars for Rivets, Pressure Vessels

　　范 圍：This specification covers the chemical, mechanical, and dimensional requirements, and associated test methods for steel rivets for use in boilers and pressure vessels, and steel bars for use in the manufacture of such rivets. Two grades of steel are covered here, as follows: Grade A and Grade B. The steel used to make the rivets shall be manufactured by open-hearth, electric-furnace, or basic-oxygen process, and the corresponding rivets shall be manufactured from steel bars conforming to the applicable bar grade ordered. The steel shall undergo heat and product analysis for measurements of chemical contents for carbon, manganese, phosphorus, and sulfur. Finished bars and rivets shall go through rivet bend, rivet flattening, bar tensile, and bar bend tests for measurements of mechanical properties such as ratio of bend diameter to diameter of the shank for rivets, and tensile strength, yield point, elongation, and ratio of bend diameter to diameter of specimen for bars.
