What is weather resistant 05CuPCrNi steel equivalent material

Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and weather resistant 05CuPCrNi steel resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, weather resistant 05CuPCrNi steel new materials, and promotes the competition of enterprises Struggle.

The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in weather resistant 05CuPCrNi steel etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.

Hot-rolled coil is a commonly used steel product in the industry. It has a relatively wide variety of products and a wide range of uses. weather resistant 05CuPCrNi steel, Hot-rolled coils are widely used in related industries such as petrochemical equipment, automobiles and bridges. Hot-rolled coils are also used in machinery industries such as ships and automobiles because of their good toughness and relatively high strength.
