Product Description
Overview of Carbon Steel, Alloy Steel and Stainless Steel Bar:
- Core Definition:
Steel bar are long strip-shaped steel products made from steel ingots or billets through processes such as hot rolling, forging, and cold drawing. According to their chemical composition, they are mainly classified into carbon steel bar, alloy steel bar, and stainless steel bar, serving as basic raw materials for manufacturing mechanical parts, structural components, and tools.
- Main Classifications: The steel bar standard system is strictly divided by application and chemical composition:
- Carbon steel bar, with iron and carbon as the main elements, are classified into low-carbon steel, medium-carbon steel, and high-carbon steel based on carbon content.
- Alloy steel bar, which are made by adding elements such as Cr, Ni, and Mo to carbon steel to achieve higher strength, toughness, or hardenability.
- Stainless steel bar, which are mainly characterized by corrosion resistance, along with heat resistance or high strength.
- Core Value Proposition:
Carbon steel bar: With their excellent cost performance and good comprehensive mechanical properties, they form the foundation of general machinery manufacturing.
Alloy steel bar: Achieve high strength, high toughness, and excellent hardenability through alloying, meeting the stringent performance requirements of key components.
Stainless steel bar: With their outstanding corrosion resistance, heat resistance, and hygiene, they become essential materials for harsh environments and high-end manufacturing industries.
