EN 10025 S620QL high strength steel material meaning

A709Gr.36 steel plate is used in construction steel structures, construction machinery and other steel structures, and has been exported to South Korea, Singapore, Malaysia, Dubai, Nigeria and other countries. The EN 10025 S620QL high strength steel) cumulative export volume has reached more than 10,000 tons. Construction steel structure, construction machinery, mining and mountain machinery, trucks, bridges, pressure vessels, especially for construction and engineering machinery parts that require good weldability and toughness.

16MnDR steel plate is suitable for low temperature pressure vessels manufacturing. Grade 16Mn- indicates that the content of manganese (Mn) in the steel plate is relatively high, about 1% -1.6%, D- indicates low temperature, R- indicates pressure vessel. (Normally, when the content of a certain chemical element in steel is high, it needs to be marked in the material, for example, 1.6% manganese is written as 16Mn; certain elements such as Cr and Mo are higher, written as Cr1, Mo1, Such as 12Cr2Mo1R.) The normal delivery status is normalized delivery (Normalized).

Titanium microalloying is an element of EN 10025 S620QL high strength steel strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in EN 10025 S620QL high strength steel tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled EN 10025 S620QL high strength steel plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive EN 10025 S620QL high strength steel industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.

When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
