1. Chemical Composition of Q195 Carbon Steel Plate (%)

Q195 is a low-carbon structural steel. Its chemical composition requirements are as follows (maximum values or ranges):

Element Carbon (C) Manganese (Mn) Silicon (Si) Sulfur (S) Phosphorus (P) Deoxidation Method

Content ≤0.12% ≤0.50% ≤0.30% ≤0.050% ≤0.045% Rimmed Steel (F) or Killed Steel (Z)

Notes:

Low-Carbon Design: Extremely low carbon content (≤0.12%) ensures excellent weldability and cold formability, but with relatively low strength.

Impurity Control: Strict limits on sulfur and phosphorus to avoid hot and cold brittleness.

Deoxidation Methods:

Rimmed Steel (F): Low cost, good surface quality, but with internal segregation.

Killed Steel (Z): Uniform composition and stable mechanical properties, suitable for critical structural components.

2. Mechanical Properties of Q195 Carbon Steel Plate

Mechanical properties of Q195 (for plate thickness ≤16mm):

Property Requirement

Tensile Strength (σ₆) 315~430 MPa
Yield Strength (σₛ) ≥195 MPa
Elongation (δ₅, 50mm gauge) ≥33% (longitudinal specimen)
Hardness (HB) ~100~130 (in as-rolled condition)

Notes:

Thickness Effect: Yield strength and elongation slightly decrease with increasing plate thickness (refer to standard classifications).

Typical Condition: Generally supplied in hot-rolled condition, requiring no heat treatment to meet properties.

Cold Bending Performance: Q195 exhibits excellent cold bending properties, suitable for complex stamping and bending processes.
