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...

Poor Carbon Control

Carburizing has an advantage over other gear case hardening processes because it increases a gear’s ability to carry high torque. Carbon control is critical to...

Process automation and controls for carburizing

Process control can be defined as the ability to meet certain parameters over time using inputs from the process and controlling outputs for desired...

Quality staff: Understanding the technical side

Last month, we examined the history and heat-treatment of aluminum and how it applies to the quality functions of the industry. This month, we...

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...

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...

Furnace atmospheres and temperature

Getting the Right Protective and Carburizing Atmosphere The makeup of a furnace’s atmosphere in the heat treating process varies based upon the application. For carburizing,...

Thermal Process Modeling

Thermal process modeling has been a hot topic in the heat treating community over the past few years. The project conducted by ASM International...

The Right Prepared Atmosphere

Furnace atmospheres are critical to meeting metallurgical specifications defined by control processes. The makeup of a furnace’s atmosphere in the heat-treating process varies based...

Furnace Atmospheres

The makeup of a furnace’s atmosphere in the heat treating process varies depending upon the application. Sensor technology allows for the in-situ monitoring of...

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....

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...

Control technology

There are many demands for precision manufacturing of steel components. Heat treatment is a critical step in nearly all manufacturing processes to achieve required...

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...

AMS2750E as it applies to Nadcap

Thorough knowledge of AMS2750E will speed implementation of new standard as it applies to NADCAP requirements

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...

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...

You can’t overlook the process

Cycle verification identifies thermal nonconformance, ensures deviation from requirements is reported

Atmosphere furnace control

Proper temperature is crucial to part quality, but don’t overlook its effect on atmosphere control
