International Equivalents


The range of International steel strip specifications is vast and it would be impractical to cover a fraction of them on this site. Below are listed the grades of steel that we have most frequently had requests for information submitted to this site. Some of these grades are exclusively steel strip, whilst others are also used in long products. There are links on the right hand site to companies and organisations that are able to offer more comprehensive steel specification data. The main standards in the United Kingdom concerned with steel strip are :-

BS4360 this is gradually being replaced by EN10025 BS1449 steel plate, sheet and strip – cross reference BS EN 10139.

BS1449 Spring Steels are slowly being replaced by EN 10132-4 (link to the right)

Micro-Alloyed Steels

A micro-alloyed steel can be defined as a carbon-manganese steel containing deliberately added alloying elements totalling only 0.05 to 0.10%. Alloying elements which are effective in modifying steel properties when present in such small amounts include boron, vanadium and niobium and boron in even lesser amounts (0.005% /0.003%).

Micro-alloyed steels are manufactured in Large tonnages for high pressure pipelines in the petroleum industry and automotive forgings.

A major advantage of these steels is that in the case of forgings, careful control of forge processing temperatures can eliminate subsequent heat treatment. This is a major cost advantage particularly with certain automotive components. Mechanical properties developed by controlled hot working conditions are similar to those developed by conventional hardening and tempering treatments for components where strength and toughness are required
