Product Description

Experience the peak of precision with our Low Carbon Steel Coil ASTM 569. Meticulously pickled and oiled, each coil promises a new realm of durability and performance.

Carbon steel, a versatile iron-carbon alloy, features a carbon spectrum from 0.0218% to 2.11%. Known for its strength and hardness, it subtly incorporates elements like silicon, manganese, sulfur, and phosphorus. A higher carbon concentration grants greater hardness and strength, expertly tailored for specific industry needs.

Classification & Grades

(1) Purpose: Categorized into carbon structural steel, carbon tool steel, and free-cutting structural steel.

(2) Deoxidation: Classified as boiling steel (F), killed steel (Z), semi-killed steel (b), and special killed steel (TZ).

(3) Carbon Content: Segmented into low carbon (WC ≤ 0.25%), medium carbon (WC 0.25%-0.6%), and high carbon (WC > 0.6%).

  • Grade 20: Exceptional plasticity and weldability, ideal for welding containers and small shafts.
  • Grade 45/40Mn: Remarkable mechanical properties post-quenching, perfect for gears and machine tool spindles.
  • Grade 65Mn: Immense strength; perfect for springs and locomotive wheel flanges.
  • T10/T11: Maximum hardness and wear resistance for taps, small drills, and dies.

Advantages of Hot Rolling

Energy Efficiency: Hot rolling slashes energy usage and costs significantly as the elevated temperature reduces resistance to deformation.
Structural Improvement: It adeptly breaks down coarse grains, mends cracks, and eliminates casting imperfections.
High Productivity: Large ingots and substantial rolling reductions heighten production efficiency and continuity.

Production Advantage
