  The demand for more sustainable development promotes the need for components and steel structures with a longer useful life and better performance.Upgrade of wear steel plate used in key industry segments such as mining,recycling and road building results in the stable growth of global market with high quality grade Q&T wear plates(Hardness HBW≥400,and Yield strength ≥690 Mpa).SSAB has now expanded its wear steel product range by both thicker and thinner Q&T plate to meet the needs of the market,and can offer wear plates from 0.7 mm to 160 mm.The continuous research and development is being done to offer even thicker plates.This article introduces the performance and advantages of high quality grade Q&T wear resistant steel products(plate,strip,tube and round bars)produced in SSAB,and also describes typical applications in some industrial segments such as material handling and construction machinery.
