Export price of s355j2 alloy plate per ton steel sheet

45# seamless steel pipe (No.45 seamless steel pipe) is Chinese high-quality carbon structural steel, which is called S45C in Japanese standard, AISI 1045 in American standard, and C45 in German standard. The difference between 45# seamless steel pipe and 20# seamless steel pipe is that its hardness is obviously higher than that of 20# seamless steel pipe. The tempering brittleness of s355j2 alloy plate, 45# seamless steel pipe is high. After quenching and tempering, 45# seamless steel pipe has good mechanical properties. If the wear resistance is considered, heat treatment is required.

Hot-rolled steel plates are 3-5 mm thick s355j2 alloy plate steel plates. The latter are used for both medium and thin plates. The use of hot-rolled plates on automobiles is mostly thick plates. In the standards for hot SLSN sheets for automobiles formulated by the Japan Automobile Association, SAPH is used for car beams and wheels, and SPH is hot-rolled mild s355j2 alloy plate steel plate for making non-stressed shells.

The mechanical properties of s355j2 alloy plate steel plate are related to elastic or inelastic reaction or related to stress-strain relationship. Tensile strength, yield point, elongation and impact absorption energy are the main indexes to express the mechanical properties of hot rolled steel plate. Its value represents the ability of steel s355j2 alloy plate to resist various actions, which is the main criterion to evaluate the quality of steel material, and also the main basis for material selection and strength calculation in steel plate design.

Previously, the coke market was both prosperous in supply and demand, and steel mills' blast furnaces were limited by the environmental protection restrictions in autumn and winter. The operating rate continued to be high, and the demand for coke remained unabated. With the continuous advancement of the coking capacity reduction process, the price of metallurgical coke will be in a price increase channel for a long time, and the mismatch of supply and demand is difficult to alleviate in the short term.
