Heat Treating

Castle Metals uses a state-of-the-art, in-house heat treating facility to deliver custom properties to carbon and alloy steel products, as well as some stainless steels.

Induction heating (induction hardening), tempered steel, and general heat treatment of steel are several things we hear as customers look to learn more about how to harden steel or what heat treatment of steel can do.

Customers that are struggling to find commercially available products that meet their specifications, challenged by growing outside processing expense, and frustrated by poor product yields or tool life often times look to heat treating options to address their problems. Castle Metals has heat treating and surface conditioning resources that our customers have come to rely upon.

Specifically, customers call Castle Metals for a variety of heat treating services that provide these benefits:

• Zero residual stress or “Stress Free” bars (annealing steel)
• Bars with consistent hardness per lot or batch (tempering steel)
• Uniform hardness on circumferences as well as surface-to-core uniformity (tempering steel)
• Consistent machinability (annealing steel)
