FERRINOX 255 is a stainless steel containing 25.5% chromium, 6% nickel with significant additions of molybdenum, copper and nitrogen and a PREn (pitting resistance equivalent) of ≥ 40.0. The copper content of 1.6% is particularly beneficial in promoting optimum resistance to corrosion in acidic environments. The chemical composition and mechanical properties conform to the requirements of UNS S32550, 1.4507 and several oil & gas industry specifications (see below). The microstructure is carefully controlled with a phase balance close to 50:50 austenite and ferrite with complete freedom from grain boundary carbides, sigma phase and other deleterious precipitates.
Hardness is kept to a level which satisfies the requirements of NACE MR01-75 for sour service. It should be stressed that, although the above standards form the basis for FERRINOX 255 supply, a consistent, optimised property combination is only achieved by the targeting of a much tighter composition window and detailed knowledge, gained from long term, volume supply, of metal processing techniques and heat treatment regimes. Rigorous testing carried out on all production batches, such as ASTM G-48A at 50°C to demonstrate very high pitting resistance and notch ductility testing at minus 46° C to confirm sub-zero suitability, also guarantees the absence of phases potentially deleterious to ductility, corrosion resistance and weldability.
