S690QL1 1.8988 high strength steel coil heavy plate production line

Manganese steel plate is a kind of common steel, which is a kind of high-strength anti manganese steel. S690QL1 1.8988 high strength steel coil, Manganese steel plate is mainly used to bear the impact, extrusion, material wear and other severe working conditions. It is a typical anti-wear steel, with austenite and carbide as cast structure. After water quenching at about 1000 ° C, the structure changes into single austenite or austenite with a small amount of carbide.

S690QL1 1.8988 high strength steel coil controlled rolling is that, on the basis of adjusting the chemical composition of S690QL1 1.8988 high strength steel coil, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of S690QL1 1.8988 high strength steel coil.

We BBN steel company have in-house machining capabilities with excellent machining experience. CNC machining-technology, We provide S690QL1 1.8988 high strength steel coil 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.

The production process of hot-rolled steel plate and cold-rolled steel plate is different. Hot rolled steel plate is rolled at high temperature, and cold rolled steel plate is rolled at normal temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. The thickness of S690QL1 1.8988 high strength steel coil cold rolling is generally smaller, and that of hot rolling can be larger. The surface quality, appearance and dimension accuracy of cold rolled steel plate are better than that of hot rolled steel plate.
