Thesteel grades are designated with steel names allocated in accordance with ISO/TS 4949.NOTE The first “B” stands for steel for reinforcing concrete. The next 3 digits represent the specified characteristicvalue of upper yield strength. The fifth letter stands for ductility class (4.4). The next symbol relates to welding; “-” meansnot intended for welding and “W” means intended for welding. The last “P” stands for plain bar.This part of ISO 6935 covers products delivered in straight lengths.Plain bars produced from finished products, such as plates and railway rails, are excluded.
