The tensile strength of A36 steel plate is 58-80 Ksi (about 400-550MPa), and the yield strength is 36 Ksi (about 250MPa); the tensile strength of Q235 steel plate is 370-500 MPa, and the yield strength is 235MPa; the tensile strength of SS400 steel plate is 400-510MPa, and the yield strength is 245MPa. For the mechanical properties of A514 grade B quenched and tempered steel, SS400 steel plate and Q235 steel plate, the thickness of steel plate is less than 16mm. It can be seen from the above data that ASME A36 and Chinese Q235 are named after the yield strength of the material, while SS400 is named after the tensile strength of the material.
What is the specific use of A514 grade B quenched and tempered steel, hot rolled plate in daily life? First of all, hot rolled plate is used in bridge, vehicle structure, frame and other fields to play a role of bearing pressure. Secondly, high pressure boiler vessels are also made of hot rolled plates, which can be heat-resistant and airtight, and can stably seal the hot gas in the container. Thirdly, stainless steel hot rolled plate can be used to process hardware products. It has excellent corrosion resistance, and is easy for processing.
In today's A514 grade B quenched and tempered steel steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of A514 grade B quenched and tempered steel market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.
The Turkish Ministry of Trade said on March 20, 2020 that Turkey has initiated a lawsuit against EU steel import tariffs with the World Trade Organization (WTO).In February 2019, the European Union stated that the sharp increase in Turkish A514 grade B quenched and tempered steel etc. steel imports has seriously threatened steel production enterprises in member states. The EU has set import quotas for 26 steel products and imposed a 25% tariff on steel products imported in the future for a period of three years.
