B400NQR1 steel plate Quenching/Hardening: The hardening treatment for B400NQR1 steel plate consists of heating the steel to a set temperature and then cooling it rapidly by plunging it into oil, water, or brine. Most steels require rapid cooling (quenching) for hardening but a few can be air-cooled with the same results. Hardening increases the hardness and strength of the B400NQR1 steel plate, but makes it less ductile. Generally, the harder the steel, the more brittle it becomes.
