Corten B steel alternatives controlled rolling is that, on the basis of adjusting the chemical composition of Corten B steel alternatives, 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 Corten B steel alternatives.
Steel is an alloy of iron with carbon, silicon, manganese, phosphorus, sulfur and a small amount of other elements. In addition to iron, carbon content plays an important role in the mechanical properties of Corten B steel alternatives and so on steel. Iron and steel is an important raw material for machinery, construction, hardware and other industries. As an important pillar industry, the development of iron and steel has a glorious period, in which Tangshan was once an important production base of China's iron and steel. This is closely related to its geographical location and energy advantages.
The outer diameter of the hot-rolled seamless pipe is generally larger than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm. The size accuracy of the cold-rolled seamless pipe is higher than that of the hot-rolled seamless pipe, Corten B steel alternatives.
Weathering steel plate Corten B steel alternatives for welding structure is made by adding chromium, molybdenum, titanium, vanadium and other metal materials into common steel liquid. Adding these materials can form a protective film on the surface, which can resist the corrosion of climate for a long time. Advantages: this kind of steel plate Corten B steel alternatives has excellent welding performance and weather resistance, and is widely used in railway, bridge and other areas requiring long-term exposure to the atmosphere.
