CS127 – Ferralium 255 – Titanium Fabricators Ltd


Materials selected for construction of plant in the chemical, petrochemical, marine and related industries depend largely upon their ability to provide an acceptable life under specific corrosive conditions. One such material frequently specified is FERRALIUM 255 (UNS S32550, Alloy 255, DIN 1.4507, ASTM F61) which offers outstanding resistance to corrosion and erosion encountered in many processes such as the manufacture of sulphuric acid, phosphoric acid, and urea and in sea water systems.


FERRALIUM 255 super duplex stainless steel has much improved corrosion and wear resistance and strength as compared with standard austenitic stainless steels and has in many cases replaced much more costly materials such as ‘alloy 20’ and HASTELLOY alloys. Fabrications in FERRALIUM 255 are often undertaken by Titanium Fabricators Ltd., Sheffield who have considerable experience in handling this material. The photograph illustrates one of four tanks that they have recently fabricated from FERRALIUM 255 plate. In this instance TIG welding was used throughout (using FERRALIUM 255 bare wire supplied by Langley alloys Ltd.), and both forming and welding presented no difficulties.


Plant made of FERRALIUM 255 also often involves the use of considerable quantities of matching FERRALIUM 255 fasteners. These are readily available from a number of fastener manufacturers.
