Product Characteristics
-
12CrNi3 is a low-carbon high alloy steel, belonging to alloy carburizing steel. It has high hardenability, is suitable for manufacturing large-section parts. After low-temperature tempering or high-temperature tempering, it has good comprehensive mechanical properties, including low-temperature toughness and low notch sensitivity.
-
Industrial Application
-
It is commonly used to manufacture the mechanical parts and tools with high strength, high hardness and high toughness.
