Material Selection
Hot forgings are generally processed using high-grade materials such as heat-resistant alloys, high-temperature alloys, stainless steel, and high-strength alloy steel. Ordinary forgings, on the other hand, use materials such as ordinary carbon steel and alloy steel. Due to the difference in materials, hot forgings have significant advantages in high-temperature resistance, corrosion resistance, and mechanical strength.
Processing Technology
Hot forgings utilize high-temperature deformation processing technology, with temperatures generally exceeding 1000℃. This allows for fast processing speeds, large deformation amounts, and completion within a short cycle. Ordinary forgings, however, are typically hammered or pressed at room temperature or in a softened state, resulting in a longer processing cycle.
Performance Characteristics
Due to the differences in materials and processing technology, hot forgings and ordinary forgings also differ significantly in their performance characteristics. Hot forgings possess high strength, high toughness, high hardness, high precision, and high heat resistance, and exhibit good dimensional stability under both low and high temperature environments. Ordinary forgings, while inexpensive, easy to process, and capable of producing large quantities, are slightly inferior to hot forgings in terms of strength, toughness, and precision.
Although both hot forgings and ordinary forgings are metal parts manufactured through forging processes, they differ in material selection, processing techniques, and performance characteristics. When selecting and using these two types of forgings, we should choose based on actual needs.
