Metallurgy

At Maynard Steel Casting Company, metallurgy is at the heart of everything we do. Our legacy of producing clean, high-performance steel castings is built on a deep understanding of metallurgical science and decades of foundry expertise. We take pride in delivering superior steel components with exceptional structural integrity, mechanical performance, and consistency.

Through specialized refining methods such as argon purging and Calcium-Silicon (CaSi) bar treatment, we engineer steel with outstanding purity, consistency, and durability. These processes help control non-metallic inclusions, reduce gas content, and improve microstructural quality—ensuring long-term performance in demanding applications like mining, construction, defense, and energy.

We achieve clean steel through:

  • Tightly controlled melting practices
  • High-purity charge materials
  • Precision alloying and temperature control
  • Specialized refining techniques

Our in-house metallurgy team works in close collaboration with heat treatment, quality, and production departments to tailor each alloy to its intended application—ensuring the right microstructure, mechanical properties, and compliance with customer specifications.
