ASTM 36 is the most common alloy steel. It is used for most building components, including columns, beams, decorations, and completion elements. ASTM A36 EN steel grade S275JR material ductility does not allow the alloy to be used as a cable or as reinforcement (reinforcement). However, ASTM A36 is also perfect for most other purposes.

Temperature has a great influence on the strength of the material, EN steel grade S275JR material. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.

The main applications of normalizing are as follows:① For low carbon steel, EN steel grade S275JR material. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.
