The Applied Technical Services Family of Companies (ATS FoC) offers decarburization testing to determine the depth and extent of carbon loss in steel and other ferrous components. Decarburization occurs when elevated temperatures cause carbon to migrate from the surface during forging, heat treatment, or machining. Our metallurgical testing enables manufacturers to detect surface carbon loss, assess material condition, and verify compliance with specifications and performance standards.
Can Decarburization Testing Identify Heat Treatment Problems?
Decarburization testing detects heat-treatment issues by measuring the depth of affected surface regions. Excessive heating, improper furnace atmospheres, or inadequate process controls can lead to carbon loss. Because carbon content influences hardness, strength, and wear resistance, excessive decarburization can compromise steel component performance. Testing helps identify:
- Excessive surface carbon loss
- Inadequate heat treatment control
- Abnormal material conditions
- Potential processing inconsistencies
How Do Our Decarburization Testing Services Evaluate Steel Components?
Our laboratory uses metallographic preparation, microscopic examination, and hardness evaluation to assess decarburization. We measure decarburization depth and analyze the microstructure beneath the surface. Our services support testing of ferrous and nonferrous materials, with a focus on steel components requiring controlled carbon content and surface properties. We perform decarburization depth analysis according to recognized industry methods, including ASTM E1077, SAE J121, and SAE J419, as applicable.
Our services can support applications involving:
- Fasteners and machined components
- Automotive and industrial parts
- Heat-treated steel products
- Metallurgical failure investigations
How Does Decarburization Testing Support Manufacturing Quality Control?
Decarburization testing provides manufacturers with measurable evidence that heat treatment processes achieve the required material condition. Engineers can compare decarburization depth to specifications and acceptance criteria to identify process deviations before components enter service. Results also support process optimization, supplier qualification, production audits, and investigations into unexpected hardness or strength. Including metallographic evaluation in quality control programs helps manufacturers understand how thermal processing affects performance and durability.
