Nimax Steel

Nimax Steel

Steel name: Nimax
Diagram No.: 2738
Chemical composition in weight %: 0.10% C, 0.30% Si, 2.50% Mn, 3.00% Cr, 0.30% Mo, 1.00% Ni
Steel group: Plastic mould steels
Properties: Uddeholm Nimax is a low carbon plastic mould steel delivered at a hardness of ~ 40 HRC.
Applications: Uddeholm Nimax is suitable for many different types of applications within the plastic segment. Its excellent machinability and high toughness also makes it suitable as a holder material as well as for many engineering applications.
Reference: Not shown in this demo version.

Heat Treatment
Case Hardening: The surface hardness can be increased by case hardening. 2h at 850°C (1560°F) and a carbon activity of 0,65 followed by tempering 1 h at 170°C (340°F) gives a surface hardness of 650 MHV and a case hardening depth of 0,3 mm (0,012”).
Tempering: Uddeholm Nimax is intended to be used in the delivery condition. The hardness cannot be increased by heat treatment, but can be decreased by tempering. However, tempering is not recommended because it significantly decreases toughness in spite of the fact that the hardness is reduced.
Diagram note: No data.
