Principal Features

HAYNES® HR-120® alloy (UNS N08120) alloy is a solid-solution-strengthened heat-resistant alloy that provides excellent strength at elevated temperature combined with very good resistance to carburizing and sulfidizing environments. Its oxidation resistance is comparable to other widely used Fe-Ni-Cr materials, such as alloys 330 and 800H, but its strength at temperatures up to 2000ºF (1095ºC) is significantly higher, even in comparison to Ni-Cr alloys. The alloy can be readily formed hot or cold, and is commonly welded using HAYNES® 556® filler wire.

Applications

Applications include those which require high strength combined with good resistance to carburizing and sulfidizing environments such as the following:

• Bar Frame Heat Treating Baskets                                        • Radiant Tubes

• Wire Mesh Furnace Belts and Basket Liners                       • Cast Link Belt Pins

• Muffles, Retorts                                                                    • Recuperators

• Heat Treating Fixtures                                                          • Fluidized Bed Components

• Waste Incinerators

HR-120® alloy heat treat furnace basket and mesh liner. This 3/8 inch diameter rod frame basket has replaced 1/2 inch diameter baskets in similar design in 330 and 600 alloys. This reduction in rod diameter is equivalent to a 43% weight reduction.

Heat Treatment

HAYNES® HR-120® alloy is furnished in the solution annealed condition, unless otherwise specified. Depending on the product form, the alloy is solution annealed at a temperature ranging from 2150 to 2250 °F (1175 to 1230 °C) and rapidly cooled.

Dynamic Oxidation

Burner rig oxidation tests were conducted by exposing samples of 3/8” x 2.5” x thickness (9mm x 64 mm x thickness), in a rotating holder to the products of combustion of 2 parts No. 1 and 1 part No. 2 fuel burned at a ratio of air to fuel of about 50:1. Gas velocity was about 0.3 mach. Samples were automatically removed from the gas stream every 30 minutes and fan-cooled to near ambient temperature and then reinserted into the flame tunnel.

Carburization Resistance

HAYNES® HR-120® alloy has good resistance to carburization. Results from 1800°F (982°C) carburization testing show HR-120® alloy to be better than stainless steels. Both pack and gaseous carburization test results are presented.

Metallographic Technique used for Evaluating Environmental Tests

Comparative Sulfidation Resistance

Independent outside testing laboratories have also verified the superior performance of HR-120® alloy in sulfidizing environments. Petten Establishment in the Netherlands found that HR-120® alloy performed significantly better than alloys 800H, 347SS and 321SS at 1290°F (700°C) in hydrogen plus 7 percent carbon monoxide plus 1.5 percent water vapor plus 0.6 percent hydrogen sulfide. The HR-120® alloy was found to be magnitudes better than the other alloys.

Hot Corrosion Comparison

Hot corrosion is an accelerated oxidation or sulfidation attack due to a molten salt deposit. This form of corrosion is seen in gas turbines as well as in other industrial environments. The hot corrosion resistance of the HR-120® alloy was evaluated by performing laboratory burner rig testing. The burner rig used No. 2 fuel oil with a sulfur content of about 1 weight percent and air to generate the test environment. The air-to-fuel ratio was maintained at 35 to 1. The test was run at 1650°F (900°C) for 500 hours with a two-minute cooling cycle to less than 400°F (205°C) every hour. During testing a synthetic sea salt solution (ASTM D1141-52) was continuously injected into the combustion zone. The following photographs show the appearance of the specimens after testing. Specimens of 253 MA, RA 85H, RA 330, and 800H alloys were either severely corroded or partially destroyed. On the other hand, the HR-120® alloy specimen still looks extremely good, showing little attack.

Welding

HAYNES® HR-120® alloy is readily welded by Gas Tungsten Arc Welding (GTAW), Gas Metal Arc Welding (GMAW), Shielded Metal Arc Welding (SMAW), and resistance welding techniques. Submerged Arc Welding (SAW) is not recommended as this process is characterized by high heat input to the base metal and slow cooling of the weld.  These factors can increase weld restraint and promote cracking.

Base Metal Preparation

The welding surface and adjacent regions should be thoroughly cleaned with an appropriate solvent prior to any welding operation.   All greases, oils, cutting oils, crayon marks, machining solutions, corrosion products, paint, scale, dye penetrant solutions, and other foreign matter should be completely removed.  It is preferable, but not necessary, that the alloy be in the solution- annealed condition when welded.

Filler Metal Selection

HAYNES® 556® filler metal (AMS 5831, AWS A5.9 ER3556) and MULTIMET® (AMS 5794) coated electrodes are recommended for joining HR-120® alloy. When dissimilar base metals are to be joined, such as HR-120® alloy to a stainless steel, HAYNES® 556® filler metal and MULTIMET® coated electrodes are again recommended. Please click here or the Haynes Welding SmartGuide for more information.

Preheating, Interpass Temperatures, and Postweld Heat Treatment

Preheat is not required. Preheat is generally specified as room temperature (typical shop conditions).   Interpass temperature should be maintained below 200°F (93°C). Auxiliary cooling methods may be used between weld passes, as needed, providing that such methods do not introduce contaminants.  Postweld heat-treatment is not generally required for HR-120® alloy.  For further information, please click here.

Nominal Welding Parameters

Details for GTAW, GMAW and SMAW welding are given here. Nominal welding parameters are provided as a guide for performing typical operations and are based upon welding conditions used in our laboratories.
