Product Description
Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. It is also called carbon steel.Steel is a general term for iron-carbon alloys with a carbon content of 0.02% to 2.11% by mass. The chemical composition of steel can vary greatly. Steel containing a small amount of manganese, phosphorus, silicon, sulfur and other elements and a carbon content of less than 1.7% is called carbon steel. In actual production, steel often contains different alloying elements depending on its use, such as manganese, nickel, vanadium, etc. Humans have a long history of application and research on steel, but until the invention of the Bain steelmaking process in the 19th century, steel production was a high-cost and low-efficiency task. Today, steel has become one of the most used materials in the world with its low price and reliable performance. It is an indispensable component in the construction industry, manufacturing industry and people's daily life. It can be said that steel is the material basis of modern society.
Step bolts are a kind of fasteners with special design, usually composed of three parts: hexagonal head, step and screw. Its characteristics are that the hexagonal head and step are formed in one piece, the step part can increase the support force, and the screw is used to connect the fastener. Step bolts are widely used in many fields.Construction field: used to connect large structural parts to ensure the stability of buildings.Mechanical field: used to connect machine parts to ensure the stability and accuracy of the machine.Automobile field: used to connect wheels and steering parts to ensure the safety and stability of vehicle driving.Heavy machinery: such as cranes, excavators, etc., are widely used because they can withstand higher preload and good anti-loosening performance.
