Why Choose TFG for Steel Investment Casting

TFG USA provides steel investment casting, a lost wax process for producing near net shape steel components. With 45+ years of engineering experience, we offer drawing feasibility reviews, medium to high volume production, and ISO 9001:2015 certified quality inspections.

We work with a range of carbon and alloy steels, including grades 1020, 1045, 4140, and 4340, as well as other customer-specified steel alloys.

Wax injection, ceramic shell building, dewaxing, molten steel pouring, cooling, and shell removal for consistent investment cast steel components.

QMS 9001:2015 certified inspections, dimensional checks, CMM inspection, material documentation, and alloy composition review for steel investment casting programs.

We plan casting features around process tolerances commonly held at ±0.005 inches per inch, draft angles, wall thicknesses, and internal cavities.

Steel Investment Casting Equipment We Use

Automatic Wax Injection Machines

Our automatic wax injection machines create consistent wax replicas that carry part details into the ceramic shell and support dimensional accuracy.

Ceramic Shell Molding Systems

We build ceramic shells with ceramic slurry, fine sand stucco, and common binders such as colloidal silica or ethyl silicate for molten steel pouring.

Steam Autoclaves (Dewaxing)

We remove wax replicas with steam autoclaves before mold firing, and investment casting operations commonly fire ceramic shells in flash-fire ovens around 1000°C.

Induction Melting Furnaces

We melt steel above its melting point in specialized induction furnaces, using controlled power input and temperature control before pouring.

Steel Alloys for Investment Casting We Work With

Steel investment casting supports common stainless, carbon, low-alloy, and precipitation-hardening steels selected around strength, corrosion resistance, and heat response.

304 stainless steel: offers corrosion resistance through chromium content and balanced strength for stainless steel investment casting components.
316 stainless steel: provides improved corrosion resistance for cast parts exposed to moisture, chemicals, or washdown conditions.
17-4 PH stainless steel: a precipitation-hardening steel that combines strength, hardness, and dimensional stability after heat treatment.
Carbon steel: offers strength and cost-effective castability for heavy-duty components with standard mechanical requirements.
Low-alloy steel: Low-alloy steel adds strength, wear resistance, and toughness for investment cast steel parts under higher loads.
Other customer-specified steel alloys: we manufacture steel investment castings to customer-specified alloy composition, drawing, and material documentation requirements.

Secondary Processes and Finishing Capabilities

We support secondary operations for steel investment castings that need machined datums, adjusted surface finish, heat response, cleaned edges, or assembled interfaces.

CNC machining: We refine holes, threads, mating faces, and datum surfaces, and separate machining tailings for scrap metal recycling.
Heat treatment: We adjust hardness, strength, and dimensional stability for carbon steel, low-alloy steel, and 17-4 PH stainless steel castings.
Grinding and finishing: We refine as-cast Ra (Roughness Average) and can bring steel investment castings to common surface targets such as 125 RMS where specified.
Electropolishing: We improve stainless steel investment casting surfaces by smoothing microscopic peaks on exposed metal.
Deburring: We remove residual shell, flash, and sharp edges from investment cast steel parts through deburring, water blasting, and mechanical knock-off.
Assembly: We combine cast steel components with specified mating parts, hardware, or subcomponents after inspection and finishing.
