The HAYNES\u00ae<\/sup> and HASTELLOY\u00ae<\/sup> alloys fall into two main categories:<\/p>\n\n\n\n

Corrosion-resistant Alloys (CRA)<\/strong>, which are generally used at temperatures below 1000\u00b0F, and are able to withstand corrosive liquids.
High-temperature Alloys (HTA)<\/strong>, which are generally used above 1000\u00b0F, at which temperatures they possess considerable strength and resistance to hot air and\/or other hot gases.<\/p>\n\n\n\n

The high-temperature alloys can also be sub-categorized according to the mechanism used to provide their strength. Many of the alloys contain significant quantities of atomically-large elements; these provide strength through a mechanism known as solid-solution strengthening. Other HTA materials use a mechanism known as age-hardening (also known as precipitation-hardening) to attain the required strength levels. There is also one age-hardenable, corrosion-resistant alloy.<\/p>\n\n\n\n

The heat treatments required to strengthen the age-hardenable materials are normally performed after welding and hot\/cold-working, and prior to these heat treatments, there is much in common with the fabrication techniques\/parameters employed with the solid-solution strengthened alloys, as long as they are supplied in the annealed condition.<\/p>\n\n\n\n

As with the stainless steels and other alloy systems, it is advantageous to have a rudimentary understanding of the metallurgical changes that might occur in the HAYNES\u00ae<\/sup> and HASTELLOY\u00ae<\/sup> alloys, if exposed to the heat of welding, the high temperatures involved with hot-working, or the effects of annealing after cold-working. If brazing is to be attempted, it is very important to understand how the temperatures involved with brazing might affect the HAYNES\u00ae<\/sup> and HASTELLOY\u00ae<\/sup> materials, or conversely how subsequent age-hardening (in the case of the age-hardenable alloys) or annealing treatments (in the case of any of the alloys) might affect the brazed joint.<\/p>\n\n\n\n

In addition to the general purpose alloys manufactured by Haynes International, there are several special purpose alloys, requiring different fabrication approaches. One is a titanium alloy made only in the form of tubulars, and for which fabrication references are given. One is a high-temperature, nickel-based alloy that requires a nitrogen diffusion treatment to impart strength to the material, and for which there are some specific fabrication issues. The other two are cobalt-based, wear-resistant alloys, one of which is not normally welded or formed; the other is easily welded, but somewhat resistant to cold-working due to a high work-hardening rate.<\/p>\n\n\n\n
