Product Description

400HBW quenched and tempered abrasion resistant low alloy steel plate

 

Description

The versatile steel that resists wear and abrasion.

400HBW is an abrasion-resistant steel with a nominal hardness of 400 HBW. 400HBW is a versatile wear-resistant steel. As a result of its high toughness, good bendability and weldability, this steel can be used in structures with moderate wear.

 

Dimension Range

400HBW is available as plate in thicknesses of 4.0 – 130 mm (5/32 - 5.12”), and as sheet in thicknesses of 2.0 - 8.0 mm (0.079 - 0.315”).

HBW steel plate is available in widths up to 3350 mm (131.89”) and lengths up to 14630 mm (575.98”). 400HBW sheet is available in widths up to 1650 mm (64.96”) and lengths up to 16000 mm (629.92”). 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). 400HBW steel plates are delivered with sheared or thermally cut edges and thicknesses over 80 mm are delivered with mill edge as standard. 400HBW sheets are delivered with an as-rolled surface and mill edge as standard.

 

Fabrication and Other Recommendations

Welding, bending and machining

400HBW 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 °C (482 °F).

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.
