What material is SMO?
austenitic stainless steel
Stainless steel grade 254 SMO™ is a very high end austenitic stainless steel. It is designed with a combination of impact toughness resistance to chloride stress corrosion cracking, and pitting and crevice corrosion with strength that is twice that of the stainless steel 300 series.
What is S31254 material?
NAS 185N (SUS 312L, UNS S31254) is a high corrosion resistant austenitic stainless steel with a high nickel, high chromium, high molybdenum alloy design, and provides excellent corrosion resistance in severe corrosion environ- ments such as high temperature seawater.
How do you weld a 254 SMO stainless steel?
For 254 SMO, SMA welding should not be used for base material less than 0.125 inch in thickness. For optimal speed and economy, the workpiece should be in the flat position. The electrode should be held at 20 degrees (drag angle) from the perpendicular, with the electrode grip inclined toward the direction of travel.
What is F44 material?
F44 is a super austenitic stainless steel. It has a PREN of 42 to 45. Super austenitic grades have enhanced pitting and crevice corrosion resistance compared with ordinary austenitic or duplex materials. F44 nickel and chromium contents makes it resistant to a wide range of corrosive environments.
What is super austenitic stainless steel?
A super austenitic stainless steel is considered to be one with a Pitting Resistance Equivalent Number (PREN) greater than 40. This is usually attributed to alloys with high additions of molybdenum, typically 6% or greater.
What is 254 SMO material?
Sandvik 254 SMO is a high-alloy austenitic stainless steel developed for use in seawater and other aggressive chloride-bearing media. The steel is characterized by the following properties: Excellent resistance to pitting and crevice corrosion, PRE = ≥42.5* High resistance to general corrosion.
What is 6Mo material?
6Mo (UNS S31254) is a super austenitic stainless steel with a high level of molybdenum and nitrogen, providing high resistance to pitting and crevice corrosion as well as high strength compared with conventional austenitic stainless steels such as 316L.
What is SMO 254?
What is SMO steel?
What is SMO pipe?
SMO 254 Welded Pipes is a very high end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content. SMO 254 EFW Pipes is an austenitic stainless steel with high molybdenum content. SMO 254 ERW Pipes is often used in Flue – gas cleaning, Desalination, Heat exchangers, and more.
