High Performance Alloys, Inc. Hastelloy® X (HX) / Hast X Disc

High Performance Alloys stocks and produces HASTELLOY X in this grade in the following forms: Bar, wire, sheet, plate, coil, fasteners and forgings.

Heat Resistant (UNS N06002)
HASTELLOY X is a wrought nickel base alloy with excellent high temperature strength and oxidation resistance. All of the product forms are excellent in terms of forming and welding. Although HASTELLOY X is primarily noted for heat and oxidation resistance it also has good resistance to chloride stress-corrosion cracking and has good resistance to carburization, excellent resistance to reducing or carburizing atmospheres. Alloy X is one of the most widely used nickel base superalloys for gas turbine engine components.

AMS 5754 has no yield or tensile strength requirements, but it does require a hardness maximum and stress rupture minimums. Strong and Oxidation Resistant to 2200 Deg. F (1200 Deg. C) - HASTELLOY X is a solid solution strengthened grade has good strength and oxidation resistance up to 2200 Deg. F (1200 Deg. C).

NITRONIC 50 Stainless Steel provides a combination of corrosion resistance and strength not found in any other commercial material available in its price range. This austenitic stainless has corrosion resistance greater than that provided by Types 316 and 316L, plus approximately twice the yield strength at room temperature. In addition, Armco NITRONIC 50 Stainless has very good mechanical properties at both elevated and sub-zero temperatures. And unlike many austenitic stainless steels, NITRONIC 50 does not become magnetic when cold worked.

High Performance Alloys can make hot rolled, cold worked, & strain hardened High Performance Stainless Steel (HPSS) bars in house. Ask for our GFM Bulletin for more information about our bar processing capabilities. We have expanded to enhance product availability.

Nitronic 60 is truly an all purpose metal. This fully austenitic alloy was originally designed as a temperature alloy, and subsequently has good high temperature properties for temperatures around 1800ºF. The oxidation resistance of Nitronic 60 is similar to Type 309 S.S., and far superior to Type 304S.S. This grade is best known for its wear and galling resistance.

The additions of Silicon and Manganese have given this alloy a matrix to inhibit wear, galling, and fretting even in the annealed condition. Higher strengths are attainable through cold working the material and is still fully austenitic after severe cold-working. This working does not enhance the anti-galling properties as is normal for carbon steels and some stainless steels. The benefit to the cold or hot work put into the material is added strength and hardness, and the wear resistance does not decrease noticeably. Chromium and Nickel additions give it comparable corrosion to 304 and 316 stainless steels, while having approximately twice the yield strength. The high mechanical strength in annealed parts permits use of reduced cross sections for weight, and cost reductions through the use of thinner stock.

Several data sheets are available on the wear compatibility of this alloy with dissimilar couples, as well as self-mated coupled results.

If your galling problem occurs at less than 1500ºF, then you should think about switching to this alloy. Nitronic 60 has a better cost advantage than any other alloy available. Other materials require an additional amount of heat treating to raise their hardness, where NITRONIC 60 is excellent in the annealed condition.

Inconel 718 is a Gamma Prime strengthened alloy with excellent mechanical properties at elevated temperatures, as well as cryogenic temperatures. Suitable for temperatures up to around 1300 F. Can be readily worked and age hardened.

Excellent strength from -423 degrees F to 1300 degrees F (-253 degrees C to 705 degrees C). Age hardenable and may be welded in fully aged condition, Excellent oxidation resistance up to 1800 degrees F (980 degrees C). Typically sold in the solution annealed temper, but can be ordered aged, cold worked, or cold worked & aged.

HASTELLOY C276 is a Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available. This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition. Alloy C-276 also has excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres up to 1900°F. Alloy C-276 has exceptional resistance to a wide variety of chemical environments.

Characteristics

• HASTELLOY C276 is one of the few alloys resistant to wet chloride gas, hypochlorite and chlorine dioxide solutions.
• HASTELLOY C276 has exceptional resistance to strong solutions of oxidizing salts, such as ferric and cupric chlorides.
• HASTELLOY C276 is not prone to grain boundary precipitation in the as welded condition and therefore suitable for many chemical process applications
