Visual and Surface Inspection

Visual and surface inspections are the initial steps in assessing mild steel quality. These inspections help detect visible defects and irregularities, such as:

Surface Inconsistencies: Identifies any surface-level imperfections, scaling, or rust.
Dimensional Accuracy: Ensures each product meets the required dimensions, shapes, and tolerances for specific applications.

Chemical Composition Analysis

Chemical composition verification is vital to ensuring that the mild steel meets precise grade specifications. Each element contributes to the steel’s properties, such as hardness, ductility, and corrosion resistance. This analysis ensures compliance with requirements for major elements:

Element	Range (%) for Mild Steel
Carbon (C)	0.05% – 0.25%
Manganese (Mn)	0.60% – 1.60%
Sulfur (S)	≤ 0.05%
Phosphorus (P)	≤ 0.04%
Silicon (Si)	≤ 0.40%

The precise composition ensures that mild steel offers the appropriate balance of strength, flexibility, and resistance for various industrial applications.

Mechanical Properties Testing

Mechanical tests confirm that the mild steel grade meets industry standards for strength, elasticity, and durability, which are crucial for load-bearing applications.

Tensile Test: Measures maximum strength under tension, confirming the steel’s ability to withstand applied forces.
Yield Strength Test: Determines the stress point at which mild steel deforms permanently.
Elongation Test: Evaluates ductility, or the extent to which the steel stretches before breaking.

Property	Typical Value Range for Mild Steel
Tensile Strength	400-550 MPa
Yield Strength	250-300 MPa
Elongation	20-25%

These tests ensure that each batch can reliably perform under various physical stresses.

Hardness Testing

Hardness tests measure the resistance of mild steel to indentation, essential for applications where surface durability is a priority. We use scales such as:

Rockwell (HRB): Commonly used for general mild steel applications.
Brinell (HB): Used for heavier applications requiring high surface resistance.
Vickers (HV): Ideal for thin or small components requiring precise hardness measurements.

Ultrasonic and Radiographic Testing

To identify internal flaws without altering the material, we conduct non-destructive ultrasonic and radiographic tests:

Ultrasonic Testing: Uses sound waves to detect internal cracks, voids, or weaknesses.
Radiographic Testing: Uses X-rays or gamma rays to visualize any hidden flaws within the steel.

These tests ensure structural integrity, essential in high-stress applications such as automotive and construction.

Dimensional Verification

Dimensional checks guarantee that all mild steel products meet specific measurement requirements, ensuring consistency and compatibility for applications like beams, pipes, and fittings. Accurate dimensions are critical for safe assembly and reliable performance.
