an iron-chromium-nickel alloy somewhat similar to a wholly austenitic type HH in general characteristics and mechanical properties.

iron-chromium-nickel alloy similar to type HK, but its higher chromium content gives this grade greater resistance to corrosion by hot gases, particularly those containing appreciable amounts of sulfur. Because essentially equivalent high temperature strength can be obtained with either the HK or HL grades, the improved corrosion resistance of the HL alloy makes it especially useful for severe service where excessive scaling must be avoided |

iron-chromium-nickel alloy containing sufficient chromium for good high temperature corrosion resistance and with a nickel content in excess of the chromium content. The alloy has properties somewhat similar to the much more widely used type HT alloy but with better ductility. It is used for highly stressed components in the 1800- 2000°F (982 to 1093°C) temperature range |

iron-chromium-nickel alloy containing about equal amounts of iron and alloying elements. The high nickel content makes this grade useful in resisting the thermal shock of rapid heating and cooling. In addition the alloy is resistant at high temperature to oxidation and carburization, and has good strength at heat treating temperatures. Except in high sulfur gases, it performs satisfactorily up to 2100°F (1149°C) in oxidizing atmospheres and up to 2000°F (1093°C) in reducing atmospheres |

iron-chromium-nickel alloy similar to type HT, but its higher chromium and nickel contents give this grade greater resistance to corrosion by either oxidizing or reducing hot gases, particularly those containing appreciable amounts of sulfur. High temperature strength, resistance to thermal fatigue, and resistance to carburization of the alloy are essentially the same as shown by the HT type; hence, its improved corrosion resistance makes the HU type especially suited for severe service conditions involving high stress and rapid thermal cycling. |

an iron-chromium-nickel alloy that is related to the HN and HT types but is higher in alloy content than either of those grades. It has the same chromium but more nickel than the HN type, and the same nickel but more chromium than the HT alloy. This combination of elements makes the HP composition resistant to both oxidizing and carburizing atmospheres at high temperatures. The alloy has good creep-rupture properties in the 1800 to 2000°F(982 to 1093°C) |

iron-chromium-nickel alloy in which nickel is the predominant element. The high nickel content contributes toward the excellent resistance of the alloy to carburization and also makes this grade especially useful in applications where wide and rapid temperature fluctuations are encountered. In addition, the alloy is resistant at high temperature to oxidation and, although not as strong as the HT type, has good strength at heat treating temperatures. It performs satisfactorily up to about 2050°F (1121°C) in strongly oxidizing atmospheres and up to 1900°F (1038°C) in oxidizing or reducing products of combustion provided that sulfur is not present in the gas |

iron-chromium-nickel alloy similar to type HW, but containing more nickel and chromium. The increased chromium content confers substantially improved resistance to hot gas corrosion, even in the presence of some sulfur, which permits this grade to be employed for severe service applications at temperatures up to 2100°F (1149°C). High temperature strength, resistance to thermal fatigue, and resistance to carburization of the alloy are essentially the same as shown by the HW type |
