Publication about the requirements of the new standard for the grade B500SP

Turn on JavaScript!

The publication contains the requirements of the new PN-H-93220:2018-02 standard for reinforced steel grade B500SP. Steel properties and methods of testing are presented.

Currently, technological progress has made it possible to achieve high strength of reinforcing steel while maintaining good ductility parameters. The method of controlled cooling popular in the metallurgy, which involves intensive spraying of the rod with high pressure water in the last phase of rolling, makes it possible to achieve high strength without increasing the carbon content. This results in maintaining the high ductility of the steel and ensuring proper weldability.
