Product application

Hot-rolled products have excellent properties such as high strength, good toughness, easy processing and forming, and good weldability, so they are widely used in manufacturing industries such as steel, construction, machinery, boilers, and pressure vessels.

Application range:

(1) Processing into ordinary cold rolling after annealing;

(2) The galvanizing unit with annealing pretreatment device processes galvanizing;

(3) Panels that basically do not need to be processed.

1. Chemical Composition of SS400 Carbon Steel Coil (Mass Percentage %)




Element Content Range (Max.) Remarks




Carbon (C) ≤0.30% Slightly higher than Chinese Q235B but within a broader range.
Manganese (Mn) ≤1.60% Higher Mn content enhances strength and toughness.
Silicon (Si) ≤0.35% Controlled via Si deoxidation; specific content adjusted by mills.
Phosphorus (P) ≤0.050% Limited to reduce cold brittleness.
Sulfur (S) ≤0.050% Controlled to minimize hot-rolling crack risks.
Residuals Cu≤0.30%, others unrestricted Complies with general structural steel requirements.

Notes:

SS400 is a common structural steel under the Japanese standard. Symbol meanings:

SS: Steel Structure

400: Minimum tensile strength (≥400 MPa)

JIS standard allows flexible chemical composition; refer to mill test reports for specifics.




2. Mechanical Properties




Property Value/Requirement Test Conditions & Remarks




Yield Strength (Rp0.2) ≥245 MPa For thickness ≤16mm. Reduced values for thicker plates (e.g., ≥235 MPa).
Tensile Strength (Rm) 400–510 MPa Broad range, suitable for medium-load structural components.
Elongation after Fracture (A) ≥17% (thickness ≤16mm) Decreases with thickness (e.g., ≥15% for thickness >40mm).
Impact Energy Not mandatory Higher grades (e.g., SM materials) required for low-temperature toughness.
Bending Performance 180° cold bending without cracks (d=1.5a) d: bend diameter; a: specimen thickness (≤16mm).

Additional Notes:

Thickness Effect: Mechanical properties degrade with increased thickness (e.g., yield strength ≥215 MPa for thickness >40mm).

Delivery Condition: Typically hot-rolled with surface oxide; post-treatment (e.g., sandblasting, pickling) available.

Weldability: Low carbon equivalent (Ceq≈0.30%). Compatible with conventional welding methods but requires controlled heat input.
