A36 steel is the code of American ASTM Society for carbon steel. ASTM A36 steel A709 Gr 50S bridge steel plate is the most commonly used steel in construction. Unlike high-performance alloys, the properties of A36 steel enable it to be used in many fields. A36 steel is very popular in building application!

The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the A709 Gr 50S bridge steel plate product workpiece, thereby improving the production efficiency and production processing quality.
On October 30, the Ministry of Ecology and Environment issued the "Action Plan for Comprehensive Control of Air Pollution in the Yangtze River Delta Region in the Fall and Winter of 2020-2021". The "Plan" stated that the steel production capacity of Tianjin will be controlled at 15 million tons by the end of December 2020. Around this time, Hebei’s steel production capacity will be controlled within 200 million tons, and the elimination of 4.3-meter coke ovens with longer furnace age and poor furnace conditions will be accelerated, and independent coking companies will gradually withdraw.
