High-Resistance Heating Alloy
High-resistance heating alloy is a subclass of special thermal alloys developed in the 2020s. It is characterized by excellent electric heating performance, high-temperature oxidation resistance and superior creep resistance. As a result, high-resistance heating alloy has become one of the most important materials in modern engineering and manufacturing.
At present, high-resistance heating alloy is primarily used for various heating devices and components, household electrical appliances, and other electrical and thermal equipment. This alloy is composed of several alloying elements, including nickel, chromium, tungsten, or molybdenum, and can reach temperatures in excess of 1600°C. The furnace heating speed of this alloy can reach 20-60°C/min, and it can maintain a long-term stable heating temperature with low-temperature drift and strong temperature uniformity.
High-resistance heating alloy has an outer layer of chromium and nickel that form a protective coating to resist high temperature oxidation, while its inner core consists of a tungsten-molybdenum alloy that resists creep at high temperatures. This alloy is heat treated to obtain a homogeneous structure with evenly distributed secondary phases and small grain size, which further increases the creep strength and oxidation resistance of the high-resistance heating alloy.
High-resistance heating alloys have great potential for use in a variety of applications. It can be used in a variety of chemical processes, metallurgical operations, and thermal engineering applications, such as power generation and waste incineration. Its greatest advantage is its outstanding resistance to high-temperature oxidation and superior creep resistance when exposed to higher temperatures.
High-resistance heating alloy is a very promising material, and it has been widely used in many fields since the introduction of GB1234-85. This standard provides guidelines and regulations for the production, quality inspection, and industry application of high-resistance heating alloy, solidifying the material’s widespread use in various engineering and industrial applications.
High-resistance heating alloy has many advantages, including its outstanding resistance to high-temperature oxidation and superior creep resistance. Thus, this material can be applied in many areas, such as chemical processes, metallurgical operations, and thermal engineering.
