X65Mo belongs to the steel plate for oil and gas transmission pipelines and pipe fittings.X65Mo steel plate pipeline steel has high strength, high toughness, so that the indicators of the steel plate can meet the standards of submarine pipeline steel.
X65Mo belongs to the steel plate for oil and gas transmission pipelines and pipe fittings. Pipeline steel refers to the hot rolled coil or wide and thick plate for large welded steel pipes used for transporting oil and natural gas. Pipeline steel in the process of use, in addition to the requirement of high compressive strength, but also requires a high low temperature toughness and excellent welding performance.
X65Mo sheet pipeline steel adopts low carbon and micro-alloying design, combined with controlled rolling and good cooling process. The X65Mo steel plate manufactured has high strength and high toughness, so that the indicators of the steel plate can meet the standards of submarine pipeline steel. The strength and toughness of the steel plate are better than that of X65 steel plate.
