Rolling process of 09CuPCrNi-B steel properties
45Mn2 steel is added with manganese on the basis of No. 45 steel. After quenching and high temperature tempering, 45Mn2 steel can obtain high strength and good toughness, that is, it has good comprehensive mechanical properties, and is often used in manufacturing larger load shafts, connecting rods, fasteners, etc. The price of 45Mn2 steel is higher than that of No. 45 steel, 09CUPCRNI-B steel properties. And the performance of 45Mn2 steel after heat treatment is better. 45Mn2 steel can be used as parts under higher stress and wear conditions, such as universal joint shaft, axle, connecting rod cover, friction plate, etc. The performance of 45Mn2 steel after heat treatment is better than No. 45 steel and worse than 40Cr steel.
With the increase of temperature, the yield limit of 09CUPCRNI-B steel properties will decrease monotonically, but the tensile strength of 09CUPCRNI-B steel properties will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of 09CUPCRNI-B steel properties. Near the blue brittleness temperature, the 09CUPCRNI-B steel properties strength increases and the plasticity decreases. The elongation and section shrinkage of 09CUPCRNI-B steel properties increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
