At ZCMIM, we specialize in stainless steel, low alloy steel and special alloys for MIM. In addition, we can also provide special or custom materials for any property requirement.

Contact us for your special metal choice, we can manufacture your precision MIM parts with many other materials.

Stainless Steel

Metal Injection Molding (MIM) process can achieve high density, enhance strength, ductility and corrosion resistance of stainless steel. All these materials are manufactured from pre-alloyed or elemental blend stainless steel with different grades of austenitic, ferritic, martensitic and precipitation hardening.

Stainless Steel 316L

Stainless steel 316L (UNS No. S31603) is widely applied in reason of its characteristics of high creep resistance, excellent form-ability, high corrosion and pitting resistance. This metal also has excellent elongation and ductility, and non-magnetic. Components of this metal are used in electronic, marine and medical industry. MIM stainless steel 316L is safe for food and water storage in reason of it high strength and corrosion resistance characters. These properties can resist potential of break down and chronic corrosion in contact with acids. Low carbon and high alloy consistence ensure MIM 316L is a great fit for food grade application.
