Prime S690QL specification pdf corrugated steel roofing sheet

35CrMoA steel has high static strength, impact toughness and higher fatigue limit, higher hardenability than 40Cr, high creep strength and endurance strength at high temperature, long-term working temperature can reach 500℃; plasticity during cold deformation Medium, poor weldability. Alloy steel S690QL specification pdf is used as important structural parts that work under high loads, such as transmission parts of vehicles and engines; rotors, main shafts, heavy-load transmission shafts of steam turbine generators, and large-section parts.

At the same time of doing well in S690QL specification pdf production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the S690QL specification pdf technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

We BBN steel company have in-house machining capabilities with excellent machining experience. CNC machining-technology, We provide S690QL specification pdf plate products both conventional and CNC machining services to offer the following machined processes :lathe turning, milling, up to 5 axis cnc, grinding, surface, od and id, threading, single point and grinding, drilling, reaming, and tapping, boring.

Q355GNHE corten steel is characterized by adding a small amount of Cu, P, Cr, Ni and other alloying elements to the steel, so that the steel material forms a dense layer between the rust layer and the substrate with a thickness of about 50 to 100 μm and good adhesion to the substrate metal. The amorphous spinel oxide layer prevents oxygen and water in the atmosphere from penetrating into the steel substrate, slows down the rust development to the steel material, S690QL specification pdf, and greatly improves the steel material's resistance to atmospheric corrosion.

We guarantee to provide all technical data required by users within one hour to provide reasonable quotation; to provide S690QL specification pdf reasonable quotation for products consulted by users within one hour; to provide investigation reception: we guarantee to receive the investigation of users at any time and provide various convenient conditions for users.
