Product Description

4Cr13 steel, a martensite stainless steel, has a high hardenability, good polishing properties,
excellent resistance to corrosion and hot oxidation Due to these excellent properties, 4Cr13
stainless steel can be applied in several important fields, such as precision mechanism,
structural automotive application, and petrochemical industry. During the manufacturing
process, the heat treatment has a significant effect on the mechanical properties of 4Cr13
components. The strength and hardness of 4Cr13 components could remarkably increase
after quenching and tempering.

Heat Treatment of 4Cr13 steel

1.Annealing
750 to 800°C for about 2 to 5 hours
slow controlled cooling of 10 to 20°C per hour to about 650°C;
further cooling in air, max. 200 HB

2.Hardening
1000 to 1050°C
15 to 30 minutes keeping curing temperature
quenching in oil/compressed gas/hot bath
obtainable hardness: 53 - 56 HRC

3.Tempering
slow heating to tempering temperature immediately after hardening, to 180 to 300 °C depending on desired hardness
1 hour per 20 mm: min. 2 hours

 

Applications

Used in corrosion resistance, wear resistance of high quality plastic mold.
