FAQs

How do I choose the right heat treater for defense and military applications?

Selecting the right heat treater is critical when processing components for defense and military programs.

Start by choosing a company that maintains Nadcap accreditation, which verifies that its personnel, equipment, processes, and quality systems meet the rigorous requirements of the aerospace and defense industries. Nadcap accreditation is widely recognized by major defense contractors and OEMs as a benchmark for consistent, high-quality thermal processing.

If your project involves Federal Contract Information (FCI) or Controlled Unclassified Information (CUI), cybersecurity should also be part of your evaluation. As the Department of Defense continues implementing the Cybersecurity Maturity Model Certification (CMMC) program, companies throughout the defense supply chain are expected to comply with the applicable CMMC requirements for their contracts. Be sure to verify that your heat treater has the appropriate cybersecurity controls and assessment status for handling sensitive information.

For defense work, it is also advantageous to partner with a U.S.-owned commercial heat treater that operates facilities exclusively within the United States. This helps support ITAR compliance, strengthens supply chain security, and provides confidence that sensitive defense-related information and components remain within the United States.

With more than 40 years of experience supporting the defense industry, Solar Atmospheres combines advanced vacuum heat treating technology, nationwide processing capacity, rigorous quality systems, ITAR compliance, and ongoing CMMC implementation to support some of the nation’s most demanding military and defense programs.

Are AMS and MIL specifications the same?

Not exactly. While many Military (MIL) specifications and Aerospace Material Specifications (AMS) cover similar heat treatment requirements, they are not always interchangeable.

Over the years, many legacy MIL specifications have been revised, superseded, or replaced by AMS specifications developed by SAE International. However, many defense contracts and engineering drawings still reference specific MIL specifications or particular revision levels that must be followed.

Before processing your parts, review the engineering drawings and contract requirements carefully. An experienced commercial heat treater can help determine the correct specification, revision level, and processing parameters to ensure full compliance with customer, military, and aerospace requirements.

Why is vacuum heat treating preferred for defense applications?

Many defense components are manufactured from high-performance materials such as titanium alloys, nickel-based superalloys, stainless steels, tool steels, and other specialty alloys that require precise thermal processing.

Vacuum heat treating provides several important advantages over conventional atmosphere processing, including:

Bright, clean, oxide-free surfaces
Minimal distortion
Elimination of decarburization
Precise control of metallurgical properties
Excellent repeatability for critical components
Compliance with stringent aerospace and defense quality requirements

These benefits make vacuum heat treating the preferred choice for mission-critical military components where reliability, performance, and consistency are essential.

What types of defense components can be vacuum heat treated?

Commercial vacuum heat treaters routinely process a wide variety of defense and military components, including:

Aircraft engine components
Structural airframe parts
Landing gear components
Missile and munitions hardware
Armor system components
Naval and submarine components
Satellite and space defense hardware
Fasteners, forgings, castings, and machined components
Additive manufactured (3D printed) defense parts

Whether supporting prototype development, qualification testing, or full-rate production, an experienced vacuum heat treater can provide the quality, documentation, and process control required for today’s defense programs.
