Flat steel refers to steel with a thickness of 12-300mm, 4-60mm, a rectangular cross-section, and slightly blunt edges. Pingda Steel, a flat steel supplier in Foshan, is a manufacturer of hot-rolled flat iron and flat steel strip processing.
Steel is an iron carbon alloy with a carbon content between 0.04% and 2.3%. To ensure its toughness and plasticity, the carbon content generally does not exceed 1.7%. In addition to iron and carbon, the main elements of steel include silicon, manganese, sulfur, phosphorus, and so on.
There are various methods for classifying steel, and the main methods are as follows:
[Classified by Quality]
Carbon steel: Low carbon steel (C ≤ 0.25%); Medium carbon steel (C ≥ 0.25-0.60%); High carbon steel (C ≥ 0.60%).
[Classified by forming method]: Hot rolled steel/Cold drawn steel.
[Classified by metallographic structure]: Normalized state: Pearlite steel; Bainitic steel; Martensitic steel; Austenitic steel.
[Classified by purpose]
Ordinary carbon structural steel; Low alloy structural steel; Reinforced steel.
Spring steel bearing steel
Tool steel: Carbon tool steel; Alloy tool steel; High speed tool steel.
Boiler steel, pressure vessel steel, agricultural machinery steel, etc.
[Comprehensive classification] Alloy structural steel; Spring steel; Easy cut steel; Bearing steel; High quality structural steel for specific purposes.
