A technical guide to quenching
From a quality perspective, verification of the conformance of quench requirements can be accomplished by examining a furnace chart that shows the quench trend....
Quality management is vital in heat-treating
Quality management in the thermal-processing industry is essential to not only conformance, but also as a check-and-balance to both systems and operations. Quality at...
The importance of contract review
Within any aspect of our business structure, understanding the specific requirements needed to produce product that conforms to customer requirements is important. These requirements...
Pyrometry, Industry Standards, & Temperature Uniformity Surveys
In its simplest sense, pyrometry is the measurement of temperatures. Practically speaking, in the business of heat treatment, the term also refers to the...
AMS2750E, Nadcap requirements
When I consult, I will periodically perform a gap analysis on a supplier’s heat-treat process to either obtain Nadcap approval or as a check-and-balance...
An argument in support of Nadcap
I think it is safe to assume that the majority of Thermal Processing readers have, in some capacity and at some point in their...
Process quality control in heat treatment
In thermal processing, process quality control is imperative to produce and control conforming product and overall conformance. In this article we will be examining...
Method means comparing checklists vs. procedure
Whether commercial heat-treating or captive, procedures are essential to the production of conforming product and its repeatability. Procedures can be challenging to write at...
Compliance via internal procedures
Verification of compliance is two-fold; witnessing operations being performed in accordance with internal procedures. As long as procedures are followed, the challenge in conformance...
Purchasing a furnace: Quality concerns to consider
For any heat-treater, whether captive or commercial, purchasing a furnace is the largest investment that can be made. It is important to establish a...
Gas Nitriding
In general, nitriding of parts involves a thermal process that provides a tough, corrosion-resistant, and wear-resistant surface with less distortion compared to other case...
Getting Control — Let’s Start with PID
It does not matter what thermal treatment work piece requires, proper control is the foundation for repeatability and quality processing. For heat-treating processes, there...
True Carbon Potential
The relationship between a carbon-rich atmosphere and its effects on low-carbon steel are well known. The evolution of carburizing led to in-situ monitoring of...
The State of Process Controls
It is hard to find a market segment that has not benefited from technology advancements. Heat-treating process control is no different. While there are...
