High Carbon Steel Wires: Unrivaled Strength and Precision from Baoli Iron Steel

At Baoli Iron Steel, we specialize in manufacturing High Carbon Steel Wires, meticulously engineered to deliver exceptional performance in the most demanding applications. With a carbon content typically ranging from 0.60% to over 1.00%, our wires are renowned for their superior hardness, impressive tensile strength, excellent wear resistance, and remarkable fatigue life.

Key Characteristics & Material Composition

• Precise Carbon Control: Our High Carbon Steel Wires are available in various grades, including but not limited to AISI 1060, 1070, 1080, 1090, and specific spring wire grades like SWC (Japanese Standards) / SWP (Japanese Standards), ensuring the optimal balance of strength and ductility.
• Enhanced Alloying Elements: Beyond carbon, the controlled addition of elements such as Manganese (for improved hardenability and strength), Silicon (for deoxidation and enhanced elasticity), and trace elements contributes to the wire’s overall superior mechanical properties and consistent performance.
• Optimized Microstructure: Through advanced drawing and heat treatment processes, our wires achieve a fine pearlitic structure, critical for maximum strength and resilience.

Superior Mechanical Properties & Manufacturing Excellence

Our manufacturing process involves state-of-the-art cold drawing and precise heat treatment techniques, including processes like patented drawing, quenching, and tempering. These processes are crucial for achieving the following mechanical properties:

• High Tensile Strength: Ranging from 1000 MPa (145 ksi) up to 2800 MPa (400 ksi) or higher, depending on the specific grade and diameter, ensuring the wire can withstand extreme loads without failure.
• Exceptional Hardness: Capable of achieving hardness levels suitable for wear-intensive applications, often up to 60 HRC after appropriate heat treatment.
• Excellent Fatigue Resistance: Vital for applications involving cyclic loading, such as springs, ensuring longevity and reliability.
• Good Wear Resistance: Ideal for components exposed to friction and abrasion.
