The development of matching composition supermartensitic welding consumables is presented. It is shown that the newly developed supermartensitic metal cored wires OK Tubrod 15.53 and OK Tubrod 15.55 produce high quality welds with properties which match requirements when used with realistic fabrication welding procedures.
Duplex ferritic-austenitic stainless steels have been used for problems in the oil and gas in problems in the oil and gas in tensitic stainless steels are, how ever, finding increasing application as an economical option, offering corrosion performance between that of carbon steel and duplex stainless steel (refs. 1-5).
