Heat Number Traceability
Engineering definition, metallurgical mechanisms, standard testing specifications, and manufacturing guidelines for closed-die forgings up to 50 kg.
Quick AnswerFeatured
The permanent alphanumeric identification stamped onto each forging linking it directly to the exact ladle melting furnace batch and chemical analysis records.
Technical Explanation & Metallurgical Principles
Full traceability is non-negotiable in critical energy and aerospace procurement. The heat number is die-stamped onto each component's rim or hub. This number cross-references the raw material mill test certificate, ladle chemical spectrometry, heat treatment furnace chart, and mechanical tensile/impact test coupons.
