Welding of 14CrlMoR steel and its application in chemical plant installation
14CrlMoR steel has been widely used in ammonia synthesis tower,coke tower,hydrogenation reactor and other important equipments in petrochemical industry for its good heat resistance,oxidation resistance,hydrogen resis-tance,sulfur corrosion resistance and cheapness. The compo-sition and mechanical properties of 14CrlMoR steel are sum-marized. And the weldability,key points of welding procedure,hybrid welding,existing welding problems and solutions of 14CrlMoR steel are analyzed emphatically to indicate that it and stainless steel composite plate are materials with both thermal strength and high corrosion resistance,which provides theoretical reference for better application of 14CrlMoR steel.
