Bend Test: This test helps in determining the ductility, but it cannot be considered as a quantitative means of predicting service performance in bending operations. The severity of the bending test is primarily a function of the angle of bend and the inside diameter to which the specimen is bent, and of the cross-section of the specimen. These conditions vary according to the location and orientation of the test specimen and the chemical composition, tensile properties, hardness, type, and quality of the steel specified. Test Method: IS: 1599-1985, IS: 2329-2005, IS: 3600 (P-5,6)1983 Elongation: Elongation is the increase in the length of gauge length, expressed as a percentage of the original gauge length. In the report, elongation value gives both the percentage increase and the original gauge length. Test Method: IS: 3600 (P-3)1989, ASME 5EC-lX Ultimate Tensile Strength Test: This test helps to determine the maximum stress that a material can withstand while being stretched or pulled before necking, which is when the specimen’s cross-section starts to significantly contract. Test Method: ASTM A36, IS: 1608-2005 0.2% Proof Stress / Yield Stress Test: Yield strength is the lowest stress that produces a permanent deformation in a material. In some materials, like aluminium alloys, the point of yielding is hard to define, thus it is usually given as the stress required causing 0.2% plastic strain. This is called a 0.2% proof stress. Test Method: ASTM E8 M-09 Rebend Test: The purpose of the re-bend test is to measure the effect of strain aging on steel. Test Method: IS: 1786-1986
