Stainless Steel Castings

The Affordable Stainless Steel Solution

Stainless steel 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 investment casting process produces very little waste, and is often the preferred method for avoiding the high costs of stainless steel

PCT offers stainless steel castings in a wide variety of alloys, including 300, 400, nickel based, and cobalt based. 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. 

• 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 ensures that stainless steel investment castings meet the form, fit, and function of your design.

Form – Unique stainless steel physical characteristics

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

Fit – How we make stainless steel work for you

Stainless steel is very receptive to the investment casting process. When poured, stainless steel completely fills the wax pattern mold, virtually eliminating voids and surface pitting. Parts originally requiring multiple assemblies can be converted into stronger, single parts. The simplicity of the stainless steel investment 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.
