Product Description

550HBW high strength hardened wear resistant low alloy steel structural plate

 

Description

550HBW steel, with a nominal hardness of 550 HBW and toughness close to 500HBW steel, increases wear life but not at the expense of crack integrity.

 

Dimension Range

550HBW steel is supplied in plate thickness of 8.0 – 65 mm, up to 2900 mm in width and up to 14630 mm in length. More detailed information on dimensions is provided in the dimension program.

Delivery Conditions

The delivery condition is Q or QT (Quenched or Quenched and Tempered). The plates are delivered with sheared or thermally cut edges. Untrimmed mill edges available by agreement.

 

Fabrication and Other Recommendations

Welding, bending and machining.

550HBW steel is not intended for further heat treatment. It has obtained its mechanical properties by quenching and when necessary by means of subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 250 ºC .

Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on this product. Grinding, especially of primer coated plates, may produce dust with a high particle concentration.
