S690QL data sheet manufacturing plant

42Cr2Mo steel is an ultra-high strength steel. The steel has high strength and toughness, good hardenability, no obvious temper brittleness, and small deformation during quenching. After quenching and tempering, 42Cr2Mo alloy has a higher fatigue limit and resistance to multiple impacts. Good impact toughness at low temperature, high creep strength and enduring strength at high temperature. The steel S690QL data sheet usually adopts surface quenching after quenching and tempering as the heat treatment plan.

Special boiler steel is derived from carbon structural steel, S690QL data sheet. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.

S690QL data sheet Weldability refers to the performance of the weld joint with the expected quality requirements obtained by common welding methods under specific structure and process conditions. Weldability is generally judged by the crack sensitivity and the change of mechanical properties of weld zone. The ability of steel materials to withstand bending without cracking at room temperature is called cold bending. The greater the bending capacity before crack, the better the cold bending performance of the steel material.

We have a professional production team and high-quality production equipment, and we also have a great S690QL data sheet advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the S690QL data sheet production of high-quality steel plates, steel pipes and other products that meet customer requirements.

Our company regularly visits customers, consults and follows up the after-sales service, and directly solves problems for customers. In the use of our steel materials, whether quality problems or not, the after-sales will help solve the problem as soon as possible. We promise free life-long replacement for any product quality problems. The sound after-sales service system make you free from worries.
