BS 1501 161 430 A/B

BS 1501 161 430A and BS 1501 161 430B Boiler Plate Steel

A significant part of Brown McFarlane's Boiler plate stock inventory is made up of plates certified to BS 1501 161 430A and BS 1501 161 430B. This is despite the fact that BS 1501: 1980 Part 1 was officially withdrawn on 15th February 1993. It is a steel specification that is still required by our customers and for that reason, we continue to hold stock in order to provide the best possible service.

BS 1501 161 Boiler Plate Steel

BS 1501 161 specifies requirements for fully killed carbon steel plates up to 150 mm thick in three grades which relate to minimum tensile strength. The plates may also be supplied having specified elevated temperature properties in which case they are designated with a "B" at the end of the specification rather than an "A".

Plates are supplied in the normalised condition although at the manufacturer's option the normalising treatment can be omitted for plates up to and including 40 mm thick provided that all specified property requirements are met when the steel is in the hot finished condition.
