The temperature of S690QL equivalent ASTM heat treatment

Hot-rolled coil is a commonly used steel product in the industry. It has a relatively wide variety of products and a wide range of uses. S690QL equivalent ASTM, Hot-rolled coils are widely used in related industries such as petrochemical equipment, automobiles and bridges. Hot-rolled coils are also used in machinery industries such as ships and automobiles because of their good toughness and relatively high strength.

Low-alloy structural steel plates are mainly used in machinery manufacturing and metal structural parts.
Advantages of S690QL equivalent ASTM, low-alloy structural steel plates: They have superior performance and light weight. Disadvantages of low-alloy structural steel plates: These steel plates are all killed plates. The molten steel is deoxidized before the production. When the molten steel is poured into the ingot mold, its reaction is relatively calm and there will be no boiling state. S690QL equivalent ASTM, low-alloy structural steel plates price will be more expensive.

The company adheres to the business philosophy of "excellent quality and integrity", aims to create a first-class enterprise in the S690QL equivalent ASTM industry, takes circular economy and resource reuse as the main line, takes energy conservation, emission reduction and sustainable development as the purpose, relies on advanced equipment, perfect transportation infrastructure and good reputation, and strives to become a leading enterprise in the S690QL equivalent ASTM industry with scientific management, high quality, first-class service and harmonious development

The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, S690QL equivalent ASTM tube.
