The life of a heat treat process engineer

Editor’s note: Beginning with the March 2020 issue of Thermal Processing, there will be multiple contributors to the Quality Counts column. Conrad Kacsik’s Jason...

Quality review: Heat-treat related certifications

As heat treaters, we must admit that, at the end of the day, what we feel we are paying for is a certification that...

Determining heat-treat operator training

With the fast pace of change in the heat-treat industry, it is understandable that more automation is in demand. This automation inevitably improves repeatability...

ASTM E18 and Nadcap: Rockwell hardness testing

Rockwell hardness testing is a common way to ensure the material response to heat treat is conforming and is required by applicable industry and...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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

Understanding gas composition

Evaluating furnace atmospheres for proper gas composition is the key to desired performance results

AMS2750E as it applies to Nadcap

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

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...

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...

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...

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...

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...

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...

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...

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...

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...

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,...

Furnace Atmospheres
