Heat-resisting steel castings are a type of steel castings that are specifically designed to withstand high temperature and resist thermal stress. These castings are commonly used in applications that involve extreme heat, such as in the manufacturing of furnaces, boilers, and high-temperature equipment.

The main characteristic of heat-resisting steel castings is their ability to maintain their mechanical properties and integrity at elevated temperatures. These castings are typically made from alloys that contain high levels of chromium, nickel, and other alloying elements that enhance their heat resistance.

Heat-resisting steel castings offer several advantages in high-temperature applications. They have good creep resistance, which means they can resist deformation and maintain their shape even under long-term exposure to high temperatures. Additionally, they have excellent oxidation resistance, preventing the formation of oxide scales that can lead to corrosion and degradation.

Some common grades of heat-resisting steel castings include:

1. H-series: These castings are made from high-chromium and high-nickel alloys and provide excellent creep resistance and thermal stability. They are commonly used in heat-treating equipment, furnace components, and power generation applications.

2. HK-series: These castings contain high levels of chromium and are used in applications that require good oxidation resistance at high temperatures. They are commonly used in furnace grids, radiant tubes, and other heat-exposed components.

3. HH-series: These castings are made from nickel-chromium alloys and provide high strength and excellent resistance to thermal fatigue. They are commonly used in aerospace and automotive applications.

To ensure the quality and performance of heat-resisting steel castings, they undergo a rigorous casting and heat treatment process to enhance their mechanical properties and heat resistance. Additionally, proper design and engineering practices are essential to ensure the castings can withstand the expected temperatures and thermal cycles in the application.
