ASTM A335 Alloy Tube P5

ASTM A335 boiler Pipe is used for high temperature services. The pipes are also known as 1.25Cr-0.5Mo pipes because of the chromium and molybdenum content in the material. 

ASTM A335 Gr P11 Pipe has similar strength as other A335 specification grades. The minimum yield strength is 205MPa and the minimum tensile strength 415MPa. The material can be heat treated through isothermal annealing or normalizing and tempering at temperature above 650 degrees Celsius for added strength. The ASTM A335 P11 Alloy Steel Pipe is prone to cold cracking. So the material has to be preheated for welding and post weld heat treated at a temperature range of 300 degrees to 350 degrees Celsius. The pipes have to be cooled down to room temperatures before being used in applications.

As one of the leading Sa335 P11 Pipe Suppliers we supply the products in large quantities and in various dimensions.
