Materials Processing Guide

Code for materials that can be vacuum processed:

	- Heat Treated		- Brazed		- Ion Nitrided

Alloy Steels -
Steels that contain specified quantities of alloy elements other than carbon. Parts are bright and clean after vacuum processing.

Carbon Steel -
Steels characterized by their carbon content. Three groups of carbon steels are categorized by the amount of carbon they contain and other characteristics: Group I - 0.08 to 0.25 C, Group II - 0.30 to 0.50 C, Group III - 0.55 to 0.95 C.

Exotic Metals -
Titanium, tantalum, samarium, zirconium, molybdenum, tungsten and stellite are rare metals that can be heat treated and/or brazed with high temperature alloys.

Low and Medium Alloy Metals -
Ferrous metals with low alloy content can be annealed and stress relieved by vacuum processing.

Non-Ferrous Metals -
Brass, copper and aluminum are some of the non-ferrous metals that can be vacuum processed using partial pressure.

Specialized Materials -
Activated silver alloy is used to vacuum braze carbide, graphite, metallized ceramic, glass to metal, diamond and other materials.

Stainless Steel -
Iron based alloys that contain chromium (10.5% or more) and/or nickel are valued for their corrosion resistance. Other variations include heat resistant steels and high alloy stainless steel. High alloy stainless steels add more chrome or moly to increase corrosion resistance.

Tool Steels -
Tool steels are made and processed to meet extremely high quality standards. They are used principally for dies, tools and parts that require special properties. There are over 100 different types of tool steels. Vacuum processing is also used to process High Speed Steels.
