For High-Strength Refractory Anchors and Insulation Studs

When the refractory lining and insulation in your furnace or high-temperature process vessel fails, you’re in for some costly unscheduled downtime and repairs. Those less-expensive cast anchors and fabricated studs mean frequent preventive maintanance at best, and at worst could mean your operations go down when you can’t afford to go down.

Cast or wrought refractory anchors and insulation studs made from HAYNES® 214®, 230®, and 556® alloys can keep your refractory and insulation in service where it belongs. 214 alloy has the best resistance to oxidation, and can be used at temperatures as high as 2300ºF (1260ºC). 230 alloy provides the best combination of elevated temperature strength, oxidation-resistance, resistance to nitriding and resistance to carbo-nitriding. It can be used in demanding applications at temperatures up to at least 2100ºF (1150ºC)

For sulfur-bearing, carburizing, or other high-temperature aggressive environments, the best choice may be 556 alloy. Combining exceptional strength with its environment resistance, 556 alloy provides excellent service up to 2000ºF (1095ºC).

Product Description

HAYNES 230 alloy combines excellent high-temperature strength, outstanding resistance to oxidizing environments up to 2100°F (1150°C) for prolonged exposures, premier resistance to nitriding environments, and excellent long-term thermal stability. It is readily fabricated and formed. Other attractive features include lower thermal expansion characteristics than most high-temperature alloys, and a pronounced resistance to grain coarsening with prolonged exposure to high-temperatures.

HAYNES 556 alloy combines effective resistance to sulfidizing, carburizing and chlorine-bearing environments at high temperatures with good oxidation resistance, fabricability, and excellent high-temperature strength. It has also been found to resist corrosion by molten chloride salts, molten zinc, and other aggressive environments.

HAYNES 214 alloy is the most oxidation-resistant, carburization-resistant, and chlorination-resistant alloy available as a fabricable material. Its effective use temperature limit is in excess of 2200°F (1204°C) for prolonged exposure, and up to 2400°F (1316°C) for shorter exposures.
