Standard thickness S690QL1 chemical composition

We have 4 typical production lines S690QL1 chemical composition, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.

Composite steel plate is a composite steel plate which is made of carbon steel or low alloy steel as the base material and coated with stainless steel, titanium alloy, S690QL1 chemical composition and other composite materials, or sandwiched with other metal or non-metal materials between two layers of steel and processed by pressure or blasting. It is mainly used to make chemical equipment and chemical storage tank, or obtain special functions such as shock absorption. The manufacturing methods of composite steel plate include rolling method and explosion method, but most of them are rolling method.

The company attaches great importance to systematic management, and has passed the S690QL1 chemical composition ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on S690QL1 chemical composition quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

Sulfur is a very harmful element in S690QL1 chemical composition steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of S690QL1 chemical composition steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.
