High strength bolts are threaded connectors with high strength and precision machining, commonly used in engineering fields that require high load, high pressure, and high temperature conditions, such as construction, machinery, automotive, aviation, ocean, and so on.

The materials of high-strength bolts mainly include carbon steel, alloy steel, stainless steel, etc. Choosing a suitable material can ensure that the bolts have different mechanical and corrosion resistance properties in different environments.

Carbon steel high-strength bolt materials are usually made of materials such as 45 #, 40Cr, 35CrMo, etc., which have good machinability and cost advantages. They exhibit excellent strength and toughness at low and room temperatures, but are prone to thermal expansion and loosening at high temperatures. Therefore, the application range in high-temperature and corrosive environments is relatively limited.

Alloy steel high-strength bolt materials are made of rare metals such as 4135, 4140, 4340, and 20CrMnTi, which have excellent properties such as high strength, high toughness, high temperature, and corrosion resistance. Therefore, it is widely used in engineering fields such as aviation, aerospace, automobiles, and heavy machinery.



Stainless steel high-strength bolt material is a new type of material developed for special environments, which has good corrosion resistance, excellent strength and toughness performance in low and high temperature environments. It is usually used in fields such as marine vessels, chemical equipment, and medical devices.

The mechanical properties of high-strength bolts are mainly reflected in aspects such as tensile strength, yield strength, elongation, hardness, etc. Usually, data marks are engraved on the surface of bolts, indicating information such as bolt material, specification, batch, etc., to help users choose the appropriate bolt type.

High strength bolts are important industrial connectors, and the selection and use of their materials and mechanical properties require comprehensive evaluation based on actual situations. Not only should the strength and durability of the bolts be considered, but also the physical and chemical properties of the environment in which they are used to ensure the quality and safety of the bolts.
