UNS S31254 Stainless Steel

PDF datasheet 

UNS S31254 stainless steel stockholders and suppliers TOBOGROUP suppliers of UNS S31254, a high molybdenum austenitic stainless steel specification. Its high molybdenum content combined with elements such as nickel and copper gives UNS S31254 excellent resistance to pitting and crevice corrosion. In acids containing halides it offers good resistance to uniform corrosion and is superior to other austenitic stainless steel grades.

Applications

UNS S31254 stainless steel is ideally suited for use in halide environments and widely used in the chemical, marine, oil and gas industries. Typical applications include pumps, valves, heat exchangers, flanges and manifolds.

Corrosion Resistance

UNS S31254 offers higher resistance to abrasion, erosion and cavitation erosion than other austenitic stainless grades such as 316. UNS S31254 has excellent resistance to corrosion in sea water and concentrated halide environments, with good resistance to crevice corrosion in seawater. 

Welding

Stainless steel UNS S31254 is readily weldeable with welding procedures used for other austenitic stainless steel specifications. Welding should be carried out at the lowest heat possible as due to its austenite structure it can be prone to hot cracking. We recommend you contact your welding consumables supplier who should provide you full assistance and information on welding UNS S31254 stainless steel.
