1/2 09CuPCrNi-A weathering steel material

09CuPCrNi-A weathering steel annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of 09CuPCrNi-A weathering steel annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. 09CuPCrNi-A weathering steel annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

According to a statistical study, Iran has decided to produce 33 million tons of steel in its calendar year (from March 20, 2020). A study of the performance of the mining sector affiliated to the mining and mining development and transformation organization of Iran (imidro) in the first month of the year (March 20 to April 20) shows that this month produced 5.4% of the 33 million tons produced at the end of this year. In the first month of this year, relevant enterprises in the country produced about 1797927 tons of steel, including 09CuPCrNi-A weathering steel, an increase of 1% over the same period last year.

Temperature has a great influence on the strength of the material, 09CuPCrNi-A weathering steel. 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.

ASTM A 242 GR. 1 steel plate, 09CuPCrNi-A weathering steel, A 242 GR. 1 steel plate, under ASTM standard, we can regard A 242 GR. 1 steel plate as Steel Resistant to Atmospherical Corrosion A 242 GR. 1 steel plate is one mainly of Steel Resistant to Atmospherical Corrosion, A 242 GR. 1 steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.
