BS 1501 Specification
BS 1501 621B Chrome Moly Plate Grade 621B has long been superseded by EN10028 but as our clients still make reference to this chrome moly grade, we have included details here, which should be used for cross reference purposes. 621B is a chrome moly steel for use in pressurised vessels and boilers found commonly in the oil and gas industry. The material has good tensile and yield strength and is designed to operate in higher working temperatures. 621B has good weldability and corrosion resistance.
