Mechanical Properties of the Heat Affected Zone of an X100 Grade Pipeline Steel

Materials Science Forum, 2013
The microstructure and mechanical properties of an X100 grade pipeline steel were investigated by the thermal simulation tests performed on a Gleeble-3500 thermal simulator. The results show that the steel has excellent weldability. Even if the weld heat input gets 40 kJ mm-1, the low impact toughness energy in welding coarse grain heat affected zone ...

Study on the Toughness of X100 Pipeline Steel Heat Affected Zone

2014
Microstructure-property correlation of heat affected zone (HAZ) in X100 longitudinal submerged arc welding (LSAW) real weld joint was studied in this paper. Coarse grained (CG) HAZ and intercritically reheated coarse grained (ICCG) HAZ were characterized by optical microscope (OM), electron backscattered diffraction (EBSD).

Effect of Crystallographic Texture on Anisotropy of Yield Strength in X100 Pipeline Steel

Journal of Iron and Steel Research International, 2013
Abstract The anisotropy of microstructures and mechanical properties in commercial American Petroleum Institute (API) X100 pipeline steel was systematically investigated by experimental measurements. The experimental results show that anisotropy of yield strength could be observed considerably, which should be attributed to the crystallographic ...

Effects of Finish Cooling Temperature on Microstructure and Properties of X100 Pipeline Steels

Materials Science Forum, 2016
The effect of finish cooling temperature on microstructure and mechanical properties of X100 pipeline steels were investigated through SEM, TEM and mechanical tests. The results showed that the effect of finish cooling temperature on tensile strength of studied steels were slight in the temperature range of 180°C~500°C.
