Steel Investment Foundries
NAICS 331512 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in manufacturing steel investment castings. Investment molds are formed by covering a wax shape with a refractory slurry. After the refractory slurry hardens, the wax is melted, leaving a seamless mold. Investment molds provide highly detailed, consistent castings. Establishments in this industry purchase steel made in other establishments.
Start the review with workers' compensation.
For Steel Investment Foundries, the saved research highlights workers' compensation, fire and explosion, products liability. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What are the primary end-use industries for the castings produced — aerospace, defense, medical, energy, general industrial?
- What quality certifications does the facility hold (e.g., AS9100, Nadcap, ISO 9001)?
- What type of melting equipment is used — induction, arc, or other — and what is its age and maintenance history?
- Are there any active environmental permits, compliance orders, or known contamination concerns on site?
- What is the replacement cost of the primary production equipment, and what are typical lead times for replacement?
- For Steel Investment Foundries, what should the underwriter know about prior fire, explosion, or molten metal incident with significant loss history?
- For Steel Investment Foundries, what should the underwriter know about castings supplied to aerospace, defense, or medical device applications without documented quality management systems (e.g., as9100, iso 9001)?
- For Steel Investment Foundries, what should the underwriter know about evidence of environmental contamination or active regulatory orders on site?

Steel investment foundries manufacture precision steel castings using the lost-wax (investment casting) process — wax patterns are coated with ceramic slurry, the wax is burned out, and molten steel is poured into the resulting seamless mold. Operations typically include pattern assembly, shell building, burnout furnaces, induction or arc melting, pouring, cooling, shell removal, and finishing work such as grinding and heat treatment. Castings are typically supplied to industrial, aerospace, defense, medical, or energy-sector customers.
