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....

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

Quality Counts: Producing Endothermic Gas Efficiently

One of the critical elements in the carburizing process is the ability to create a base atmosphere suitable for the parts placed inside a...

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...

You can’t overlook the process
