ASTM A335 P11 alaşım çelik Dikişsiz boru

ASTM A335 Alloy Steel Seamless Pipes
Alloy Steel contains substantial quantities of elements other than carbon like chromium, silicon, nickel, manganese, molybdenum, tungsten, vanadium as well as limited amounts of other commonly accepted elements like sulphur, manganese, silicon & phosphorous. Addition of these alloying elements is usually done for purpose of increasing hardness, strength as well as chemical resistance of the end product.

Alloy Steel Seamless Pipes (IBR APPROVED & NACE APPROVED)
Alloy Steel Seamless Pipes (IBR) offered by us is made of alloy steel and feature exceptional performance properties. These are developed for energy-related applications involving oil & gas drilling and therefore are subjected to stresses in machine parts. Further, Alloy Steel Tubes are also used in domestic, professional or industrial areas.
