smo 254 round bar 1.4547 stainless steel
254 SMO UNS S31254 EN 1.4547 stainless steel 254 smo is a kind of austenitic stainless steel. Because of its high molybdenum content, so it has a very high resistance to pitting corrosion and crevice corrosion resistance. This brand of stainless steel is used in environments such as seawater containing halide and the research and development Material: SMO 254 , 254 SMO, UNS S31254, DIN/EN 1.4547 ASTM A240 ASME SA-240 W.Nr.1.4547 F44 1.4547 Stainless Steel Bar
Main features of UNS S31254:
1, the addition of high alloy means that its pitting resistance equivalent value (PREN) ≥42.
2. Excellent corrosion resistance in seawater and concentrated halide environments.
3, high resistance to stress corrosion cracking.
4, seawater crevice corrosion resistance.
5, good corrosion resistance.
