The following data are given for each standard: standard number and year, grade, chemical composition and mechanical properties (yield point, tensile strength, notch toughness). When deemed useful, steel type, manufacturing method, thickness of plate, heat treatment and other data are described.
This group of B.S. specifications covers carbon and alloy steel plates and forgings used in boilers and pressure vessels, high-strength low-alloy steels, heat-treatable steels, spring steels, sheets and strips. This article also contains standards for various types of steel pipes which specify requirements for high-temperature service, ordinary use, and special applications such as fire protection use. Specifications for steel tubes list standard requirements for boiler and superheater tubes, general service tubes, steel tubes in refinery service, heat exchanger and condenser tubes, mechancal and structural tubing. Steel casting specifications call out the standard properties for pressure purposes. Standards for tool steels, stainless, heat resisting and valve steels are also presented
