ASTM A335 P11 Pipe Manufacturer & Supplier in India

ASTM A335 P11 contains chromium and molybdenum as the principal alloying elements. The combination is commonly identified as 1¼Cr-½Mo alloy steel, with the chemistry controlled according to the applicable ASTM specification.

P11 pipes are supplied to minimum mechanical property requirements specified for the grade.

ASTM A335 P11 is also identified by several material designations used across different specifications and industries.

ASTM A335 P11 pipe is heat treated according to the applicable ASTM requirements. P11 permits full or isothermal annealing, or normalizing and tempering, with the applicable tempering/subcritical annealing temperature specified at 1200°F [650°C] minimum in the referenced ASTM heat-treatment table.

Katariya Steel can supply P11 pipes in different NPS sizes, schedules and wall thicknesses according to project requirements. ASTM A335 uses NPS designations, while dimensional requirements for ordered pipe are commonly referenced to ASME B36.10M.

Alloy Steel P11 IBR Pipes are used where P11 alloy steel material is required for boiler, steam or related piping systems subject to applicable Indian Boiler Regulations requirements.

For IBR-related orders, material documentation, inspection and certification requirements depend on the component, application and applicable IBR provisions. Pipe certificates and material test documentation are important for establishing material identity, test results and traceability.
