Stainless Steel
Stainless steel consistes of pre-alloy and MIM material combined with elemental metal powders, including austenitic stainless steel, duplex stainless steel and precipitation hardening stainless steel.
Material Properties
MIM process improves the strength, toughness and corrosion resistance of the material. because of the high density can obtained in MIM process. MIM material in stainless steel has several grades, each has special performance and wide application range.
The MIM - 316 Austenitic Stainless Steel
The brand is available to the parts with excellen corrosion resistance. The parts made by MIM316 has a great strength and toughness.
The MIM - duplex stainless steel (316 )
Dual phase refers to the stainless steel has the ferrite-austenite composite tissue. Compared with 316, the corrosion resistance are similar, but the apparent hardness is higher, and the mechanical properties are improved more or less, These alloys are ferromagnetic.
The MIM - 17-4PH-precipitation hardening stainless steel.
It is suited the parts that need high strength
and hardness. Because of the low carbon content, its corrosion resistance is
better than 400 series stainless steel. it’s able to get a variety of different
properties and hardness by changing aging temperature during heat treatment
