UNS S30815 - EN 1.4835

Essential details
253Ma Stainless excellent service properties at high temperatures with ease of fabrication. It resists oxidation at temperatures up to 1150C andcan provide superior service to Grade 310 in carbon, nitrogen and sulphur containingatmospheres.

253MAR is a trademark ownedby Outokumpu Stainless AB, The standard arade desianation covering this grade is UNS S30815. Othermils produce arades compliant with UNS S30815, includina Sirius S15e, 253 MA contains a fairly low nickel content, which cives itsome advantage in reducing sulphide atmospheres when compared to hich nickel alloys and SS310, The inclusion of hich chromiumsilicon, nitrocen and cerium contents cives the stee aood oxide stability, high elevated temperature (creep) strenath and excellentresistance to sigma phase precipitation, The austenitic structure cives this grade excellent touchness, even down to cryogenictemperatures.
