Inconel 601 alloy steel

Inconel 601 is a nickel-chromium alloy used for applications that require resistance to corrosion and heat. This nickel alloy stands out due to its resistance to high temperature oxidation, remaining highly resistant to oxidation through 2200° F. Alloy 601 develops a tightly adherent oxide scale which resists spalling even under conditions of severe thermal cycling.
Inconel 601 alloy similar material are: UNS N06601, W.Nr.2.4851, NiCr23Fe, Alloy 601

718HH pre-hardened plastic mold steel

718HH die steel production since both maintain a high quality, low sulfur levels have been thermally pre-hardened to 36-40HRC its factory
718HH die steel vacuum melting of chromium – nickel – molybdenum alloy steel, hardened and tempered after the factory prior to treatment, with the following advantages:
1, no quenching crack and heat deformation risk
2, no heat treatment costs
3, shorten molding cycle
4, lower the cost of mold making (for example, no distortion correction)
5, the mold is easy to modify
6, can be subjected to nitriding and flame hardening treatment to enhance the mold surface hardness and wear resistance.

718HH die steel plate features:
1, excellent polishing and photo-etching properties
2, good processing properties
3, high purity and excellent uniformity
4, wear better and longer tool life
718HH die steel use:
1 . A large long-life plastic injection mold, such as home appliances, computer casings, such as mold
2, high surface finish of the plastic mold
3, blow molding
4, due to the high hardness, can be used to mold the plastic sliders
5, forming tools, Compression – Brake mode (bending machine model), (depending on production needs to be applied flame hardening or nitriding)
Factory state: hardened and tempered to hardness of about 330-370HB
