sa573 gr 70 carbon steel shapes, The wear-resistant steel plate adopts the open arc self-protection automatic surfacing process, and the composite-layer is a high-alloy wear-resistant layer with high hardness and high wear resistance on the surface of the ordinary steel plate or stainless steel plate. The wear-resistant steel plate has bimetal performance. That is, the high wear resistance of the working layer and the high plastic toughness of the base layer provide convenient mechanical connection and welding rod connection conditions for industrial applications, and can realize processing such as reeling, welding, plasma cutting, and mechanical connection.

The elongation of low alloy high strength steel is 15% - 23%, and the impact absorption energy is more than 34J at room temperature. The sa573 gr 70 carbon steel shapes, low alloy high strength steel has good plasticity and impact resistance, which can avoid brittle fracture during impact, and make cold bending and welding easy. In addition, the brittle transition temperature of low alloy high strength steel is low, and the absorbed work value of Grade E steel is not less than 27J at - 40℃. This is of great significance to the engineering components and transportation tools such as vehicles, ships, offshore oil platforms, containers, bridges and so on.
