For High-Strength Refractory Anchors and Insulation Studs<\/h3>\n\n\n\n

When the refractory lining and insulation in your furnace or high-temperature process vessel fails, you\u2019re 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\u2019t afford to go down.<\/p>\n\n\n\n

Cast or wrought refractory anchors and insulation studs made from HAYNES\u00ae<\/sup> 214\u00ae<\/sup>, 230\u00ae<\/sup>, and 556\u00ae<\/sup> alloys can keep your refractory and insulation in service where it belongs. 214\u00ae<\/sup> alloy has the best resistance to oxidation, and can be used at temperatures as high as 2300\u00baF (1260\u00baC). 230\u00ae<\/sup> 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 2100\u00baF (1150\u00baC)<\/p>\n\n\n\n

For sulfur-bearing, carburizing, or other high-temperature aggressive environments, the best choice may be 556\u00ae<\/sup> alloy. Combining exceptional strength with its environment resistance, 556\u00ae<\/sup> alloy provides excellent service up to 2000\u00baF (1095\u00baC).<\/p>\n\n\n\n
