Tensile Testing

Tensile testing determines material strength and ductility by applying axial force until fracture. Commonly used to determine tensile strength, yield strength, elongation and reduction of area.

Specific Test Performed	Test Method
Tensile Strength Yield Strength Proof Strength (0.2% & 1%) % Elongation % Reduction of Area	IS 1608 – Part 1 ISO 6892-1 ISO 4136 ASTM A370 ASTM E8 / E8M ASTM B557M / ASTM B557 AWS B 4.0 ASME Sec IX AWS D1.1 / D1.1M

Bend Test

The bend (flexural) test evaluates ductility and resistance to fracture under bending stress.

Specific Test Performed	Test Method
Bend Test	IS 1599 ISO 7438 ISO 5173 ASTM E290 ASTM A370 ASTM E190 ASME Sec IX AWS D1.1 / D1.1M

Hot Tensile — Elevated Temperature Testing

Temperature range typically from 50°C to 900°C. Used to examine strength and ductility at elevated temperatures.
