What is the price of ASTM A36 carbon steel plate sheet, spring steel? First, how much a ton of spring steel costs depends on the grade of spring steel, because different grades have different properties and prices. Second, it is also related to the market. The demand for ASTM A36 carbon steel plate sheet spring steel is different every day, and the price of ASTM A36 carbon steel plate sheet, spring steel is also changing every day. We can learn the current price of ASTM A36 carbon steel plate sheet, spring steel through the network and steel market information. Third, how much a ton of spring steel costs depends on the manufacturers. Different manufacturers have different manufacturing quality and prices. Generally, the price of large factories is higher, but the quality is better guaranteed.

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. ASTM A36 carbon steel plate sheet, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.

The steel such as ASTM A36 carbon steel plate sheet delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.

SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. ASTM A36 carbon steel plate sheet, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
