Carbon steel flat 50x10 S690QL grade vs stainless steel

Our gas cylinder steel materials steel flat 50x10 S690QL are hot selling in 2019. The order quanitity for gas cylinder steel coils and sheets amount to 10,000 tons. Among them, a large portion of the gas cylinder steel coils and sheets are exported to Uganda, Kenya and so on Africa countries for gas cylinder production companies. Now our steel flat 50x10 S690QL gas cylinder steel has taken a large market share in local. We supply both gas cylinder steel coils and gas cylinder steel sheets. The dimension is customizable.

The company adheres to the principle of integrity, standardization and efficiency, wins the market with technology, gains reputation with creative services, and wholeheartedly provides customers with high-quality steel flat 50x10 S690QL, efficient and fast services. Facing the future, adhere to independent innovation.

Q690D steel belongs to high-strength welded structural steel. Among them, Q represents the yield strength, 690 represents the yield strength value, and D represents the grade of the steel plate. The quality grades of common Q690 series steel are A, B, C, D, E. The impact of grade D steel plate is -20°C. Q690D steel can be called a low temperature resistant high strength steel with a yield strength of 690Mpa.

The chemical composition of Q345D seamless steel pipe is as follows: C ≤ 0.18, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S≤ 0.025, Nb ≤ 0.07, V ≤ 0.15, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.012, Mo ≤ 0.10, Al ≥ 0.015. steel flat 50x10 S690QL, Q345D seamless steel pipe has good comprehensive mechanical properties, low temperature impact toughness, corrosion resistance, cold stamping, machinability and weldability. Q345D seamless steel pipe is widely used in welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, etc..

In January, 2019, our South Africa customer purchased 669 tons S235J2+N carbon steel plates to use in their tank fabrication project . S235J2 steel, as a non-alloy structural steel grade, is mainly used in structural projects and tanks. J2 symbol -20 temperature impact test. The client required CEV 0.38%, S≤0.01%, 100% UT, Charpy V-notch impact test at-20℃, Z25 for S235J2+N plates. After they receiving the S235J2+N steel plates, the customer are very satisfied with the quality of this batch of steel flat 50x10 S690QL products.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our steel flat 50x10 S690QL products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
