S50C steel characteristics: the carbon content of the steel (mass fraction, %) ≥ 0.4, excellent wear resistance, reduced ductility, easy to deform and crack after quenching, so quenching is extremely important, and it must be quenched after cutting and tempering to avoid tempering brittleness. By implementing spheroidizing treatment, the cutting performance of this type of carbon steel hot rolled sheets ASTM A36 can be improved. The steel is usually used after tempering to a hardness of 19~22HRC to increase its cutting performance.
With the rapid development of economy, there are many kinds of engineering projects, and their development is very fast. However, steel is an essential material in construction engineering. At present, there are many kinds of steel products on the market. In order to ensure the construction quality, the requirements for the strength, quality and corrosion resistance of hot rolled sheets ASTM A36, steel are more and more strict.
BBN steel hot rolled sheets ASTM A36 15mm to 35mm thick size: 15*2120*5620, 17.5*2320*13000, 18*2450*5500, 20*3000*5000, 19*2580*4700, 19.5*1970*4000, 20*1600*7740, 20.5*2370*7000, 21*2650*7500, 21*1920*8220, 22*1380*7650, 22*1800*8000, 22.5*1680*8450, 23*3000*11980, 23.5*2080*8100, 24*1560*6200, 25.5*2330*8300, 26*3010*8100, 26.5*2000*7000, 27*2550*6800, 27.5*2700*5500, 29*2550*9000, 29*2870*12000, 32*3300*6000, 33*2340*6700, 34*2120*6100, 35*1300*4100.
The basic principle of hot rolled sheets ASTM A36, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.
