Stainless Steel

The Affordable Stainless Steel Solution

​Stainless steel investment castings can achieve high levels of corrosion and abrasion resistance without machining or plating, making it one of the most investment casting-friendly metals available. The stainless steel casting process produces very little waste and is often the preferred method for avoiding the high costs of stainless steel

PCT offers stainless steel investment castings in a wide variety of alloys, including 300, 400, cobalt and nickel investment castings base. We specialize in turnkey designs of stainless steel investment castings in the 0 to 20 lbs range and are equipped to produce castings up to 100+ lbs. Our design capabilities include:

  • Intricate, near-net shape parts without secondary machining
  • Easily convert multiple parts into single assemblies
  • Thin walls for weight reduction opportunities
  • Surface texture of 125 rms or better
  • Tolerances within +/- .005 inches per linear inch
  • Highly complex dimensional geometry

From concept to completion, PCT can help you meet the form, fit, and function of your design.


Stainless steel is aesthetically pleasing, and can meet any surface finishing requirement without the need for plating. Stainless steel investment castings can be polished to a mirror finish for the ultimate in corrosion resistance -- even in salty marine conditions.


Stainless steel is very receptive to the investment casting process. When poured, stainless steel completely fills the wax pattern mold to virtually eliminate voids and surface pitting. Parts that originally required multiple assemblies can be converted into stronger, single parts. The simplicity of our casting process allows for high production rates and consistent dimensional accuracy.

Stainless steels, especially precipitating hardening grades, can undergo heat treating to achieve the same mechanical properties as alloy steel while retaining native corrosion resistance. Secondary annealing is also available for applications requiring softer metals.

Additional stainless steel heating techniques include solution annealing, induction hardening, quenching, tempering, normalizing, aging, carbonizing, carbon restoring, and case hardening.


Austenitic's low magnetic permeability and versatile mechanical properties makes it ideal for sensors and electronics. Austenitic is ideal for food processing as it does not absorb the acid wash used on or near food processing machinery.

The military and optical instrumentation industries commonly employ Martensitic steel due to its ability to retain hardness, shape, and precision under extreme temperatures and conditions. Martensitic loses a portion of austenitic's corrosion resistance but outperforms austenitic in strength. Martensitic stainless steel can be precipitation hardened for addition tensile and yield strength.
