Why replace traditional steel (S10~45C) with iron-nickel alloys?

?Nickel is the best material for stabilizing austenite

1.All the added elements of iron-based metals are in the best solid solution state in the state of austenite (the lattice presents the largest gaps)

2.The hardened elements can be more easily distributed in the iron metal austenite due to the guidance of nickel, and the best hardening effect can be obtained

3.Low alloy (Low Alloy) refers to steel containing other added elements less than 3%, which is most suitable for carburizing to adjust hardness and mechanical properties, so Fe-2Ni (4605, 2700, 0205...) has low MIM Alloys are based on 2wt% Ni

4.Nickel also provides good toughness, oxidation resistance, etc., which improves the rust resistance of the alloy

5.The addition of nickel can also stabilize the existence of austenite, so that the iron-nickel alloy has good magnetic permeability. When nickel reaches 50wt%, this material has the best magnetic flux density (Fe-50Ni is second only to Fe-50Co)

6. In addition to 17-4PH and 304L, 316L of MIM metal, Fe-2Ni alloy is the most cost-effective MIM material

The disadvantage of adding nickel is only the human nickel allergy factor
