Material 09cuptire-a steel technology Chemistry

The company has allocated special environmental protection facilities for all 09CUPTIRE-A steel technology pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, 09CUPTIRE-A steel technology steel mill scale, environmental protection dust has reached 100%.

Ordinary 09CUPTIRE-A steel technology carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the steel, and generally does not add a lot of alloy elements. Ordinary carbon steel is the abbreviation of ordinary carbon structural steel. Carbon content is less than 0.38%, and less than 0.25% is the most commonly used. It belongs to low carbon steel. In the Chinese standard, each metal grade indicates the low yield point of the steel when the thickness is less than 16mm. Compared with high-quality carbon steel, the limitation of carbon content, performance range, phosphorus, sulfur and other residual elements is wider for ordinary carbon steel.

45# steel is commonly used medium carbon quenched and tempered structural steel. The steel 09CUPTIRE-A steel technology is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability. After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained. 45# steel normalizing can improve the cutting performance of roughness less than 160HBS.

During the steel plate cutting, the special-shaped steel plate cutting process is often carried out. In this operation process, some cutting curves will be generated. Therefore, there should be relatively high precision standards during the processing of 09CUPTIRE-A steel technology. The operators need to have rich experience, and they also need to be proficient in the operation methods and working skills of the equipment, so as to ensure that the steel plate can meet the shape requirements after processing.

Chemical composition of Q420 steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. 09CUPTIRE-A steel technology, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
