ZG65Mn JB /T 6402-2018 Large low alloy steel wire

ZG65Mn JB /T 6402-2018 Large low alloy steel wire，has high strength, high hardness and good wear resistance. After heat treatment, it has superior mechanical properties and is suitable for manufacturing parts that bear large loads and wear. However, the material also has certain overheating sensitivity and tempering brittleness, which need to be paid attention to in the production process.
