ASTM A537 pressure vessel steel plates are heat treated carbon manganese silicon steel plates used in pressure vessel fabrication. There are 3 grades, which are Grade 1, Grade 2, and Grade 3.

GB/T 11251 alloy steel is one of the common hot-rolled alloy structural steels. This steel coil is widely used in various applications in bearings/gears of rotating machinery.

DIN 1629 seamless steel pipe has three main grades of St37.0, St44.0, St52.0. Generally, the DIN 1629 standard is not limited to the working pressure value, and the working temperature is limited to below 300 ℃.

SAE 1006 steel wire rod belongs to low carbon steel wire rod with low carbon content and high plasticity, making it suitable for welding, cold forming, and various metal processing applications.

API Spec 5L is an international standard that specifies the manufacturing requirements for two product specification grades (PSL 1 and PSL 2) of seamless and welded steel pipes used in pipeline transportation systems in the oil and gas industry.

EN 10083-3:2006 steel is an alloy steel used for quenching and tempering. This standard regulates the technical delivery conditions of alloy steels. Under the steel 50CrMo4, 51CrV4, 20MnB5, 34CrMo4, 42CrMo4, 27MnCrB5-2. EN 10083-3 steel plate has high strength, high toughness and good hardenability. The alloy requires high temperature preheating before welding to eliminate the stress after welding.

GB/T 11251 alloy steel is one of the common hot-rolled alloy structural steel plates. This steel plate is widely used in various applications in bearings/gears of rotating machinery.

A588 alloy structural steel plate is a kind of weather-resistant steel plate, and its material standard is ASTM A588/A588M. It is a type of low-alloy high-strength structural steel and is mainly used for structural components in outdoor exposure environments, such as bridges, large containers, chimneys, etc.

DIN 17155 pressure vessel steel plate is steel for boilers and pressure vessels. In addition to boilers and pressure vessels, DIN 17155 pressure vessel steel is also used to manufacture high-temperature liquid delivery pipes.
