AISI 4140 Alloy Steel Plate 

Product description With the development of science, technology and industry, higher requirements have been put forward for materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion, wear and other special physical and chemical properties. Mild steel plate can no longer fully meet the requirements, so alloy steel plate have emerged. The steel plates are divided into thin steel plates<4mm (the thinnest 0.2mm), thick steel plates 4~60mm, and extra thick steel plates 60~115mm.The steel plates are divided into hot rolled and cold rolled according to rolling. The width of the sheet is 500~1500 mm; The width of the thickness is 600~3000 mm. The thin plates are classified into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel andindustrial pure iron thin plates; According to professional purposes, there are oil barrel…
