Stainless Steels
Kitchen sinks, refrigerator or oven doors, and tableware are what many people think of when they are asked what’s made from stainless steel (SS)....
Carburizing
While some heat treatments are used to soften the material or improve its machinability, most are processed to obtain strengthened or hardened properties. The...
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...
Q&A with Dennis Beauchesne
When was vacuum carburizing introduced?
The process has been around since the 1960s. Vacuum carburizing enables more precise control of case depth and microstructure than...
Heating with natural gas
It’s no secret that the heat treating industry is one of the major recipients of the impact when the U.S. Environmental Protection Agency (EPA)...
Hardening and tempering in the same cell
Tempering hardened steels is one of the most important heat treating processes used in part manufacturing. Induction tempering produces hardness and mechanical properties similar...
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...
Q&A with Brian Russell
Q: Tell me a little about the history of Dry Coolers, Inc.
We started in 1985 to provide cooling water solutions for heat treating equipment—for...
Intensive Quenching Calls For Very High Cooling Rates Part 2
Intensive quenching (IQ) is defined as cooling, usually using pure water, at a rate several times higher than the rate of conventional quenching. Fast,...
Materials Selection for Induction Hardening Processes
Induction hardening is the most common technique of the various types of applied energy processing. It uses alternating current that induces a magnetic field...
Intensive Quenching
Heat treating is similar to art in many ways, but not for the reasons you might think. Art, it’s said, is in the eye...
Different Scales Are Used For Rockwell Hardness Testing
Production Bench Rockwell Hardness Testing of Small Work Pieces
As induction hardened workpieces get smaller in size, attention to the proper abrasive cutting of the...
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 Maintenance
When a heat treat manager or anyone responsible for purchasing heat treating equipment makes a buy decision, they must first consider the process required,...
Q&A with Bob Wells
What are some factors one should consider in cryogenic processing of gears?
First off, what is the size I need? Secondly, how do I want...
Some workpieces are too large and expensive to fit into conventional benchtop hardness testers
Portable Rockwell Hardness Testing of Large Induction Hardened Work Pieces
The previous article identified many factors related to benchtop Rockwell hardness testing practices. This article...
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,...
Carburizing and Steel
In carburizing, gears must be heated to reach the appropriate temperature for the steel grade without causing excessive grain growth and distortion in a...
Q&A with Jim Litzinger
Your company, Orton, offers TempTabs, some pretty ingenious technology for monitoring temperature throughout a furnace. How did the idea come about?
Our founder, Edward Orton...
Site Safety
We live and work around fire all day. It’s pretty much taken for granted. We cook with it, and use it to heat our...
