China Wholesale Hardox500 Wear Resistant Steel Plate Suppliers - 316L stainless steel plate, 316L stainless steel coil – Wenyue
difference At present, the two most commonly used stainless steels 304316 (or 1.4308,1.4408 corresponding to German / European standards), the main difference between 316 and 304 in chemical composition is that 316 contains Mo, and it is generally recognized that 316 has better corrosion resistance than 304 in high temperature environment. Therefore, in high temperature environment, engineers generally choose 316 parts. But the so-called thing is not absolute. In the concentrated sulfuric aci... -
China Wholesale Coating Steel Pipe Manufacturers - Precision inner diameter seamless steel pipe for hydraulic and pneumatic cylinder barrel (GB8713-88) – Wenyue
A brief introduction of seamless pipe’s use Seamless Steel Tube is divided into hot-rolled (extruded) seamless steel tube and cold-draw n (rolled) seamless steel tube. Cold-drawn (rolled) tube is divided into round tube and special-shaped tube two kinds. Seamless steel pipe and because of its different uses are divided into the following several varieties: 1. Seamless steel tubes for structural use (GBT8162-2008). Mainly used for general structure and mechanical structure. Its representative ... -
China Wholesale Stainless Steel 201 Ba Factories - Q355b open plate – Wenyue
Properties of alloy steel With the development of science, technology and industry, higher requirements are 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. Carbon steel can not fully meet the requirements. Deficiency of carbon steel: (1) Low hardenability. In general, the maximum diameter of water quenched carbon steel is only 10mm-20mm. (2) The strengt... -
