45MnB characteristics and applications: alloy structural steel has good hardenability, the critical hardenable diameter in oil reaches 17 ~ 31mm. The machinability of steel is good, the forging and heat treatment process performance is also good, the tendency of grain growth, oxidation, decarburization and heat treatment deformation is also small when heated. 45MnB steel is mainly used for gears on machine tools, spindles of drilling machines, turning shafts and cams of tractors.
As for Q460 series low alloy steel, there are three quality Grade C, D, E. , Q460C steel plates are mainly used in various large-scale engineering structures and light-weight structures that require high strength and large load Q460C steel mechanical properties: Q460C yield strength MPa in different thickness: ≤16mm: ≥460; 16-40mm: ≥440; 40-63mm: ≥420; 63-80mm: ≥400; 80-100mm: ≥400; 100-150mm: ≥380 The tensile strength MPa: 550-720Elongation: ≥17%Impact test: 0 ℃ impact test: ≥34J,ASTM A573 structural steel carbon plate.
If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
ArcelorMittal said it was taking measures to cut its North American steel production in response to the weakening demand for downstream steel after the outbreak of covid-19, foreign media reported. It is reported that ArcelorMittal's plant in the port of Indiana is ready to shut down the No. 4 blast furnace.
