ASTM A335 Pipe (ASME S/A335, Chorme-Moly) is a seamless ferritic Alloy-Steel Pipe for high temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Sometimes referred to as “P Grade”, chome moly pipe is popular in P-Grades P5, P9, P11, P22, and P91. The most common use of grades P11, P22, and P91 is in the power industry and petro-chemical plants, Grades P5 and P9 are commonly used in refineries.
A335 is often called chrome moly pipe because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). Molybdenum increases the strength of steel as well as the elastic limit, resistance to wear, impact qualities, and hardenability.
We carry stock all brands of chrome moly material, these material from Vallourec China company (Tianda), Hengyang Valin Steel , TPCO, Chengdu steel pipe(pang steel group), Yangzhou chengde, Yangzhou long chuan, Bao steel etc.
We keep regular stock quantity over 10,000 ton, covered normal sizes pipe,fitting and flange, and also offer cutting ,heat treating, bending, beveling,surface treating and threading service for these materials. welcome contact us for details.
