Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
"In year 2014, we participate Bangladesh national railway tender for steel plate making train carriage. We finally got the order 1000 tons and it took us 40 days to produce all the plates. The client gave very high comments to our service and product quality.In year 2015, we won another tender for 1200 tons B480GNQR steel coils in Bangladesh, which you can find in the steel coil part."
The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.NM500 steel used for bridges
