A335/SA335 P5, a seamless ferritic alloy-steel pipe, serves as a dependable solution for high-temperature applications within the steel industry. With a seamless design that ensures consistency and leak resistance, these pipes meet the highest standards for reliability, a critical factor in the steel sector.

ASTM A335/ASME SA335 pipes have earned their moniker as “chrome moly” pipes due to their high chromium (Cr) and molybdenum (Mo) content, two crucial elements in the world of alloy pipes. These components are pivotal in defining the exceptional qualities of alloy pipes, making them indispensable in various applications.

Molybdenum, the other key element, augments the overall strength, resistance to corrosion, hardenability, elasticity, and overall quality of the material. Molybdenum fortifies the material, rendering it more resistant to softening, restraining grain growth, and reducing the likelihood of brittleness, ensuring durability and dependability.

When it comes to mechanical properties, ASTM A335 P5 shares similarities with Grades P9, P11, and P22. These pipes boast a minimum tensile strength of 415MPa and a minimum yield strength of 205MPa. As a result, these grades have gained widespread acceptance across diverse industries, cementing their reputation as trusted and versatile choices for numerous applications.

The ASTM A335 P5 Seamless Pipe falls within the purview of the ASTM A335 specification, adhering to the precise dimensions outlined by ASTM, ASME, and API standards. These standards are the bedrock of quality and consistency in the steel industry.

These pipes are available in a range of nominal bore sizes, spanning from a modest 1/8 inch to a substantial 30 inches. This wide range of sizes caters to diverse industrial needs, ensuring that there’s a suitable option for various applications.
