ASTM A572 high strength steel,We are a popular factory, supplier and wholesaler of mild steel plates and alloy steel plates in all over the globe We follow all standards and specifications of boiler steel plate, structural steel plate, shipbuilding steel plates and corten steel in different types We manufacture and supply steel plates, steel section and steel structures according to customer’s demand The company also focus on providing customers with high-end steels and competitive price,ASTM A572 high strength steel.
ASTM A572 high strength steel,S690QL high-strength steel is used for low temperature, high strength key components, construction machinery, mining machinery structure, etc. European standard high strength steel plate, manufacturing various types of construction machinery, such as mining and various types of construction drilling rig, electric shovel, electric wheel dump truck, mining truck, excavator, loader, bulldozer, various types of cranes, coal mine hydraulic supports and other structural parts.
35# steel is a high-quality medium carbon carbon structural steel, with good plasticity and appropriate strength, good process performance, and acceptable welding performance. It is often delivered in normalized and tempered state. 35 # steel is widely used in the manufacture of various forged and hot-pressed parts, cold-drawn and upset forged steel, seamless steel tubes, and parts in machinery manufacturing.
The chromium plays an important role in Chromium Molybdenum steel. The chromium can form a dense oxide film with strong adhesion on the surface of the steel plate, so as to prevent the internal metal from further oxidation or corrosion. The higher the chromium content in the steel plate, the denser the oxide film, and the better the oxidation resistance and corrosion resistance of the steel plate.
As to the Chemical composition, the different content is a main on carbon content, while the carbon content of A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 grade D is 230MPa (33 ksi).
