SAE10B21/10B30 cold heading steel hot-rolled coil

Features and Advantages of SAE10B21 Cold Heading Steel Hot-rolled Coil:

Good cold heading performance: It has a low original hardness and excellent plasticity, making it easy to be formed. It can be processed into various shaped fasteners such as bolts and nuts through the cold heading forming process at room temperature, and is suitable for manufacturing parts with complex shapes.

Balanced strength and toughness: It has a certain strength to meet the force-bearing requirements of parts during use, and also has good toughness, which can prevent brittle fracture during the cold heading process or in use.

Obvious heat treatment effect: The mechanical properties of the material can be significantly improved through heat treatment. After heat treatment, it has high strength and good hardenability, which can further enhance its comprehensive performance to meet different usage requirements.

Good welding performance: As a high-quality low-carbon steel, it has good welding performance and is suitable for connection by welding methods such as arc welding and contact welding. The welding quality is high, and the strength and toughness of the welded joint can meet the usage requirements.

Applications of SAE10B21 Cold Heading Steel Hot-rolled Coil:

Manufacturing of high-strength fasteners: Used for producing high-strength bolts, screws, nuts, etc.

Automotive parts: Used for manufacturing high-strength connecting parts on automobiles, such as engine bolts and chassis bolts.

Mechanical parts: Used for manufacturing high-strength connecting parts and structural parts of mechanical equipment.

Other fields: Widely applied in industries such as construction, bridges, and power equipment.

Processing Technology of SAE10B21 Cold Heading Steel Hot-rolled Coil:

Cold heading forming: Use a cold heading machine to directly process the coil material into parts of the required shape.

Heat treatment: Quench and temper the parts after cold heading to improve their hardness and strength.

Surface treatment: Surface treatments such as electroplating and coating can be carried out to improve corrosion resistance.
