L6 steel is a multi-purpose Oil hardened, heat-resistant and wear-resistant forged steel tool steel with very good toughness.
L6 tool steel is suitable for tools, molds and mechanical parts. They need a good combination of hardness and toughness. The relatively high nickel content makes the alloy have greater impact toughness than other ordinary oil hardening grades.

L6 tool steel is suitable for tools, molds and mechanical parts. They need a good combination of hardness and toughness. The relatively high nickel content makes the alloy have greater impact toughness than other ordinary oil hardening grades.
L6 STEEL CHARACTERISTICS
L6 steel is a commonly used steel for plastic molds, which has good comprehensive mechanical properties and hardenability. Hardenability refers to the range of hardness that steel can achieve during the quenching process. Steel with good hardenability can achieve a more uniform hardness for larger cross-sectional sizes. This is particularly important for manufacturing large molds, as they typically require greater pressure and load, requiring them to have higher strength and toughness.
L6 steel also has excellent polishing performance, which is an important indicator for measuring the surface quality of steel. Good polishing performance means that the surface finish of the mold made is high and the roughness value is low. This is very important for plastic molds, as the surface smoothness of the mold directly affects the surface quality of plastic products. If the surface roughness of the mold is too high, it can cause problems such as burrs and bubbles on the surface of plastic products, affecting the appearance and quality of the product.
L6 steel also has good wear resistance and corrosion resistance. Wear resistance refers to the ability of steel to maintain a low wear rate during friction, while corrosion resistance refers to the ability of steel to maintain a low corrosion rate in corrosive media. These two properties are also very important for plastic molds, as they need to withstand long-term friction and chemical corrosion during use. If the wear and corrosion resistance are insufficient, it will shorten the service life of the mold and increase production costs.
In addition, L6 steel also has certain weldability and machinability. Weldability refers to the ability of steel to maintain good welding quality and joint strength during the welding process, while machinability refers to the ability of steel to achieve good cutting performance and surface finish during the machining process. These two properties are very important for manufacturing complex mold structures, as complex mold structures often require welding and cutting processing.
