hardness

Measure the ability of mold steel to resist local deformation, especially plastic deformation, indentation, or scratches. Usually measured by methods such as Rockwell hardness (HRC) and Brinell hardness (HBW).

strength

Including yield strength and tensile strength. The yield strength represents the stress at which a material begins to undergo significant plastic deformation; Tensile strength is the maximum stress that a material can withstand before breaking.

toughness

Reflecting the ability of materials to absorb energy during plastic deformation and fracture processes, it is commonly represented by impact toughness (measured through impact tests).

Wear resistance

The ability of mold steel to resist wear is crucial for extending the service life of molds.

thermal stability

The ability of hot work mold steel to maintain stable microstructure and properties at high temperatures.

Thermal fatigue performance

The ability of materials to resist crack formation and propagation during repeated heating and cooling processes.

Hardenability

The depth of martensitic structure obtained during quenching of steel affects the overall performance uniformity of the mold.

Cutting performance

Reflect the difficulty and processing quality of the material during the cutting process.

Polishing performance

For plastic mold steel and other materials, good polishing performance can achieve a smooth mold surface.

Corrosion resistance

Some molds require certain corrosion resistance to work in specific environments.

Thermal conductivity

Hot work mold steel and some cold work mold steel that require good cooling effect need to have good thermal conductivity to quickly dissipate heat.
