About RQT 701 Quenched and Tempered Steel Plate

The steel was developed for use in applications such as mining and quarrying, process industry, material handling, construction, and earth moving. Designers, engineers, and plant operators strived 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 structura performance in extreme working environments.

Although this steel grade is no longer manufactured, Brown McFarlane offers equivalent products in our Quenched and Tempered Steel range.
Fabrication of RQT 701 Steel Plate.

RQT 701 steel plate can be easily welded and fabricated but its high yield strength and tensile strength compared with mild steel means that it should be treated with some caution. If you require more detailed advice on welding, machining, or forming then please contact any one of our offices.
