Dec 01, 2013 · The mechanical properties of heat affected zone (HAZ) of two commercial high-Nb X80 grade pipeline steels with different alloy elements were investigated using thermal simulation performed on a Gleeble-3500 thermal simulator. The results showed that the high-Nb steels have excellent weldability. Embrittlement regions appear in coarse grain heat affected Effect of Strain Aging on Tensile Behavior and Properties Aug 02, 2018 · The materials used in this study are API X60, X70, and X80 grade pipeline steels having above the yield strength level of 413 MPa (60 psi), 483 MPa (70 psi), and 552 MPa (80 psi), respectively. The detailed chemical compositions and processing conditions are provided in Tables 1 and 2, respectively. After reheating treatment at temperatures above 1100 °C, the X60
Effects of heat treatment process of quenching and tempering under different temperature conditions on mechanical properties of X70 grade pipeline steel bends were studied. Brinell hardness, yield strength, tensile strength, elongation and impact absorbing energy of the bends were tested by using hardness tester, cupping machine and impact testing machine, respectively. Estimation of the local mechanical properties of pipeline Jan 01, 1998 · In the present work, a microshear test method has been used to investigate the local mechanical properties distribution of API X60 grade pipeline steels and their welded joints, including microshear strength, microshear plasticity and microshear toughness.
