B400NQR1 Steel Quenching/Hardening: The hardening treatment for B400NQR1 steels 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, but makes it less ductile. Generally, the harder the steel, the more brittle it becomes.
B400NQR1 Steel Solution treatment: Solution heat treatment involves the heating of a B400NQR1 to a suitable temperature, holding at that temperature for sufficient time to induce one or more of the constituents to enter into solid solution and then cooling rapidly enough to hold these constituents in solution. This kind of hear treatment is mainly used for the Stainless steel, Aluminium alloys, Titanium alloys, Beryllium copper alloys, Inconel and associated heat resisting alloys, Nickel base alloys, Maraging steels products.
