1.4547 (also called UNS S31254, 254 SMO and SS2378) is a high alloyed austenitic stainless steel with exceptional corrosion resistance. The steel is developed for use in halide-containing environment such as seawater, hydrochloric acid and contaminated sulphuric acid. 1.4547 has a superior resistance to uniform corrosion compared with common stainless steel, especially in acids containing halides.  It has a high content of alloy materials which gives the steel exceptionally good resistance to pitting and crevice corrosion. The steel also have very good resistance to stress corrosion cracking.

Alloys 254 / 254 SMO / 6 Mo is an austenitic stainless steel with a high molybdenum content. Coupled with Nickel and Copper this gives the alloy a good resistance to pitting and crevice corrosion, especially in environments containing halide ions, e.g. chloride, bromide and fluoride solutions.

254 SMO (UNS S31254) may offer a cost effective solution to Nickel and Titanium alloys in these environments.

Good formability and weldability of DIN 1.4547:
1.4547 has a good weldability and the methods used for welding conventional austenitic steels are used. It is somewhat more sensitive to hot cracking and shall be welded with low heat input.

Filler metal of type Welding P12 or P16 are recommended. These filler metals will give a weld with a resistance to pitting corrosion. The steel can be both cold and hot formed. Due to a higher strength and alloy materials the steel is difficult to machine.
