What is 254 SMO Plate?
Designed to be used in seawater as well as other aggressive chloride bearing environments, the UNS S31254 is a highly alloyed austenitic stainless steel grade.
254 SMO Plate
Alloy 254 6 Mo Sheet
UNS S31254 Coils
The plates produced from 254 SMO exhibit excellent resistance to pitting as well as to crevice corrosion. In fact, the PREN value of this stainless steel grade sheet is more than 42.5. The yield strength of this high alloy grade coil is 310 Mpa and shear modulus valued at 75 GPa, whereas the melting point for Alloy 254 SMO shim stock falls in between the temperature range of 1320℃ - 1390 ℃.
Depending on the needs of the buyer, the surface of these 254 6mo stainless steel sheets could be finished using value added treatments such as Hot rolled plate or as known as HR, Cold rolled sheet or as referred to as CR, Satin finish that is Met with Plastic Coated. Additionally, a No.1 finish hot rolled 254 SMO En 1.4547 Plate along with options such as 1D, 2B, 2D,8K, BA NO(8), hairline, brush, No.4, BA, a mirror finish could be conducted on these plates. If required these sheets or plates could be left bare.
What is ASTM A240 UNS S31254 Sheet?
The ASTM A240 is a specification that caters to several components such as plate, coil, sheet, and strip manufactured from chromium based alloy, like the UNS S31254 which can be used to build pressure vessel as well as for general applications. Apart from the chemistry requirements, the mechanical requirements for these components made from W.Nr. 1.4547 are also specified.
