S690Q steel are cost effective

The company has S690Q steel advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience S690Q steel, we have accumulated a large number of customers at home and abroad, and won unanimous praise.

Low alloy steel plate was originally developed for large diameter oil and gas pipeline in 1960s. Pipeline steel materials used in oil and gas projects require higher strength and toughness than low carbon steel, and have good weldability just the same as low carbon steel.Advantages: S690Q steel, Low alloy steel plate has superior performance and light weight.Disadvantages: Low alloy steel plate is killed steel, so the price will be more expensive.

Grades S690Q steel, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of S690Q steel, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

S690Q steel, SS400 steel is one of the most commonly used hot rolled general structural steel. SS400 steel’s mechanical properties is yield strength more than 225-235MPa, tensile strength 360-510Mpa and 340-470Mpa. For SS400 steel, the C element content is 0.2% max, the Mn element content is 1.40% max, the P element content is 0.045% max, the S element content is 0.045% max.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality S690Q steel products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
