Quenched and Tempered Steel Plate RQT 701

<div>Designers, engineers, and plant operators strive to reduce weight and increase the efficiency of equipment. There are significant benefits to be had by using high strength quenched and tempered steels for maximum structural performance in extreme working environments.</div><div><br></div><div>We often find that this type of material is called different things by different engineers.
