What is the hardness of S275J2 carbon steel plate sheet?

Our company was founded in 2000, which initially committed to providing high-quality steel S275J2 carbon steel plate sheet products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export S275J2 carbon steel plate sheet steel to the international market, opening up the international steel market.

A516Gr.65material is a carbon steel plate for medium and low temperature pressure vessels, which implements the ASTM A516 standard of the American Standard. The S275J2 carbon steel plate sheet) product minimum thickness that can be provided is 8mm and the width is 1500~4000mm. It has sufficient strength and toughness, good welding performance and hot and cold processing performance. A516Gr.65 steel plate can be used to manufacture pressure vessel steel for petrochemical, gas separation and gas storage, oil storage tank and transportation equipment.

Corrosion resistant steel is a kind of stainless steel, which can resist corrosion in some strong corrosive media. Stainless steel can only resist corrosion in air or weak medium. Stainless steel is not necessarily corrosion resistant, corrosion-resistant steel must be stainless steel. Corrosion resistant steel is durable and can be stored outdoors for a long time without being damaged in bad weather. Corrosion resistant steel is not easy to rust, but it is not absolutely rust free. The strength, precision and toughness of S275J2 carbon steel plate sheet, corrosion resistant steel are very good, and can be the processed and used for many purposes.

For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In S275J2 carbon steel plate sheet, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.

S355NL steel plate is under EN10111 standard. We can regard S275J2 carbon steel plate sheet, S355NL steel plate as Fine-grain structural steels, normalised rolled. S355NL steel plate is one mainly of Fine-grain structural steels, normalised rolled, The normalized rolled fine-grain structural steel S355NL is characterized by a minimum yield strength of 355 MPa, by good weldability and high resistance to brittle fracture, which is same with DIN:TStE355 and BS:55EE
