GB 45Mn

GB 45Mn is a high-quality alloy steel that is widely used in the manufacture of high-strength, high-wear mechanical parts and industrial equipment.

One of the outstanding properties of this steel is its hardness and strength, which makes it widely used in many physically demanding situations.

In addition, GB 45Mn also has excellent corrosion resistance and plasticity, which allows it to maintain good performance in extreme environments, suitable for industrial equipment in a variety of industries.

While discussing the advantages of GB 45Mn, we must also see some limitations and problems. For example, the temperature and handling conditions need to be strictly controlled during use to ensure that its performance and durability are not affected.

• Chemical composition: C: 0.42% - 0.50%, Si: 0.17% - 0.37%, Mn: 0.50% - 0.80%, Cr: 0.25% or less, Ni: 0.30% or less, the Cu: 0.30% or less, P: 0.035% or less, S: 0.035% or less.
• Mechanical properties: strength, toughness, hardness are high, widely used in the manufacture of high-strength parts and mechanical structures.
