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, mechanical 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.
The most common BS steel standards are listed below, but if you do not find the grade you require please contact our experienced sales team
BSI, the business standards company, has revised its standard for cold-formed welded steel. BS EN ISO 4957:2018 Tool steels replace the previous version of this standard published in 1999.
The revised standard will be of particular interest to producers of wrought tool steels; welding manufacturers; structural steel manufacturers; and all types of hot-rolled, forged, cold-drawn, or cold-rolled products.
Specifically, BS EN ISO 4957 lists the requirements for the following grades of wrought tool steels:
Non-alloy cold-work tool steels
Alloy cold-work tool steels
Alloy hot-work tool steel
High-speed tool steels
Below we list our range of British Standard tool steel and high-speed steel grades.
