Quenched & tempered S420ML equivalent ASTM material specification chart machinability

S960Q plate implements standard EN10025-6S960Q plate application: European standard high-strength steel plate, corresponding to the national standard Q960. S420ML equivalent ASTM material specification chart, S960Q plate is suitable for manufacturing various construction machinery, such as drilling rigs, electric shovel, electric wheel dump trucks, mining vehicles, excavators, loaders for mining and various engineering construction, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts.S960Q plate delivery status: normalizing, normalizing + tempering, quenching and tempering, etc.;Technical requirements for S420ML equivalent ASTM material specification chart, S960Q plate, S420ML equivalent ASTM material specification chart: UT, Z15-Z25-Z35 thickness direction performance requirements, high-strength and high-toughness.

Temperature has a great influence on the strength of the material, S420ML equivalent ASTM material specification chart. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.

Common medium thick and heavy steel plates are widely used for manufacturing various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low steel alloy steel plates, bridge steel plates, general steel plates, boiler steel plates, pressure vessel steel plates, pattern steel plates, automobile girder steel plates, tractor parts and welding components. S420ML equivalent ASTM material specification chart, bridge steel plates are used for large railway bridges. They are required to bear dynamic load, impact, vibration, corrosion resistance, etc.

The Brazil steel is facing a "crisis of demand" as the epidemic of new crown pneumonia spreads in Brazil. The demand for S420ML equivalent ASTM material specification chart and so on steel will be reduced by 50% in April. The demand for the second quarter will be 40% lower than that in the first quarter. The demand for this year will be reduced by 20% compared with the same period this year. In 2019, Brazil's apparent steel consumption was 20.6 million tons, a year-on-year decrease of 2.7%; crude steel production dropped to 32.33 million tons, the lowest since 2016 (30.2 million tons).
