A709 Gr 50W structural steel,EN10113 S275M is a technical delivery conditions for thermomechanical rolled weldable fine grain structural steels.S means the structural steel, M means the delivery condition.Capital letter L for the quality with specified minimum values of values of impact energy.The EN10113 S275M steel is equivalent to DIN StE285TM,UNI FeE275KGTM..
A709 Gr 50W structural steel,45# steel is commonly used medium carbon quenched and tempered structural steel. The steel is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability. After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained. 45# steel normalizing can improve the cutting performance of roughness less than 160HBS.
The effect of alloy elements of Q345B alloy steel plate on tempering transformation: improving the tempering stability The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved,A709 Gr 50W structural steel.
The toughness of steel is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.
