The main alloy components of A335 P92 boiler tube are Cr:9%, Mo:1%, etc. Compared with SA-335P91 steel tube, SA-335 P92 seamless boiler tube appropriately reduces the content of Mo element, and adds a certain amount of W, which increases the molybdenum equivalent (Mo+0.5W) of the material from 1% of P91 steel to about 1.5%. High temperature strength and creep properties are improved. This enables it to be used in ultra-supercritical units and environments above 600 degrees Celsius.
A335 P92 high-pressure boiler tube is suitable for bending, curling and similar forming processes as well as fusion welding, and can be selected according to the design, working conditions, mechanical properties and high temperature characteristics.
