SM490B grade steel technical parameters

Shipbuilding steel plates are used to manufacture marine and inland watercraft hulls, requiring high strength, plasticity, toughness, cold bending performance, welding performance, and corrosion resistance. The company provides common shipboard grades such as Grade A, Grade B, Grade D, Grade E, Grade AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH32, SM490B grade steel FH36, FH40.

Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the SM490B grade steel steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like SM490B grade steel, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.

It is a modern high-tech professional enterprise integrating scientific research, SM490B grade steel production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as SM490B grade steel process technology development, technology transfer and related technical consulting and technical services.

With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel SM490B grade steel product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue.
