Austemper Heat Treatment

Master is one of the few custom stamping manufacturers with heat treatment capabilities in house.  As a result, we control everything from quality to lead time making certain only quality conforming parts are produced and delivered on time. 

With over 35 years of Austemper heat treating experience, a convenient Midwestern location, quick turnaround and certified quality and environmental systems, Master clearly has the advantage.

We are also one of the few captive heat treat operations that accepts outside work, meaning we can heat treat your existing steel parts. The same quality, delivery and cost effective advantages apply to your heat treating needs. Contact us for details.

Austemper Heat Treatment Capabilities:

Heat Treatment Type

Austemper, thru hardening

Materials Heat Treated

Carbon Steel from C1050 to C1095

Hardness Achieved

Rockwell R/C 40 to 50, or as needed depending on steel type

Part Types Processed

Small metal parts, such as stampings, clips, clamps, fasteners, pins, etc.

Part Size and Weight

Material thickness of .006″ to .200″, up to 5″ long, weighing 2 pounds


2 Austemper lines manufactured by CAN-ENG and SELAS


Computer controlled time, temperature, atmosphere and weight

Loading Method

Automated controlled weight and through put by use of magnetic carrier which protects fragile parts before hardening from bending or damage


On site laboratory testing for hardness from R15N scale to R/C, product specific testing available,   IATF 16949 Certified Quality Systems (PDF)

Lead Time

7 to 10 days, expedited service available

Through Put Capacity

500 pounds per hour plus


Endothermic Gas

Endothermic Gas

To increase strength, hardness, toughness and wear resistance of steel

Heat Treating Advantages

Allows for use of thinner (and therefore less costly) steel thickness without loss of strength. Parts bend and then “spring back” to their original shape.

Austemper Advantages

Reduced distortion as parts retain more of their original shape, provides higher ductility (much less brittle), produces superior microstructures, reduces the possibility of hydrogen embrittlement caused by supplemental finishes such as electroplating or acid cleaning.
