Hardness: 5Cr5WMoSi has high hardness, generally reaching HRC45-50, which ensures
stable working performance of the mold for a long time under high temperature and high
pressure conditions.
Heat resistance: 5Cr5WMoSi has excellent heat resistance, maintaining its strength and hardness
for a long time in high-temperature environments without softening or deforming easily.
Wear resistance: 5Cr5WMoSi exhibits outstanding wear resistance under friction and wear
conditions, maintaining good surface quality even after prolonged use.
Corrosion resistance: 5Cr5WMoSi has good corrosion resistance, allowing it to be used for
a long time in harsh environments such as moisture, acids, and alkalis without rusting or deteriorating.
Machinability: 5Cr5WMoSi has good machinability and can be processed and formed into
complex mold structures through processes such as heat treatment, cooling, and cutting.
Heat treatment process: Proper heat treatment, including annealing, quenching, and tempering
processes, is required before processing 5Cr5WMoSi to enhance its structure and performance.
Temperature range: The working temperature range of 5Cr5WMoSi is generally between 500°C
and 600°C, exceeding this range may cause material softening and damage.
Surface treatment: Surface treatment techniques such as electroplating, spraying, and nitriding can
be employed to improve the corrosion resistance and surface quality of 5Cr5WMoSi.
Application areas: 5Cr5WMoSi is widely used in high-temperature working environments such
as plastic molds, aluminum die-casting molds, and hot pressing molds, greatly improving the
service life and efficiency of molds.
