What is the production process of A573Gr.70 steel for bolted and welded structures

Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important A573Gr.70 steel for bolted and welded structures heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.

42CrMo steel plate is a strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering treatment, and good low temperature impact toughness. The steel A573Gr.70 steel for bolted and welded structures is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness.

For a ship, the choice of medium and thick ship plate is very important, it is an important part of the ship frame. The pressure bearing capacity of A573Gr.70 steel for bolted and welded structures, medium and thick ship plates is very strong. Secondly, because it is a ship plate, it must be driven in water, so of course the corrosion resistance is better, otherwise it will bring danger to buyers. Moreover, the service life of the ship will be increased. Regular inspection of the ship plate can ensure the safety of sailing. You can also know whether the ship plate is defective, so you don't have to worry about water seepage when you sail.

The wear-resistant composite plate, A573Gr.70 steel for bolted and welded structures should be pre heat treated to eliminate the residual stress produced in the machining process. If conditions permit, vacuum heating quenching and cryogenic treatment after quenching should be selected as far as possible. On the premise of ensuring the hardness of steel plate, pre cooling, step cooling and quenching or high temperature quenching should be selected as far as possible. For some wear-resistant composite plates, pre heat treatment, aging heat treatment and quenching, tempering and nitriding heat treatment can be used to control the accuracy of the wear-resistant composite plate.

A573Gr.70 steel for bolted and welded structures, HP265 steel with the thickness range is 1.2-12mm. HP265 steel’s mechanical properties is include the yield strength more than 265MPa, tensile strength is 410-520MPa. The chemical composition of HP265 steel is C element content is 0.18, the Si element content is 0.10, the Mn element content is 0.80, the P element content is 0.025% max, the S element content is 0.015% max.

Our company stocks a wide range of hot rolled carbon steel plate distributed globally from our service centers in the U.S., Canada, Mexico, U.K, France, Shanghai, and Singapore. Customers calling for A573Gr.70 steel for bolted and welded structures A516 a lot of times are also trying to get their arms around forecast issues. As our customers continue to work on their forecasts, IRON & Steel has options to help you conduct structured forecast reviews and put inventory strategies in place to effectively manage any impact from forecast variability.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
