254 SMO Round Bar

ASTM A276 6mo UNS S31254 Rod and Flat bar manufacturer and supplier.


smo 254 welding bars

SMO is a high alloyed stainless steel developed by Sandvik. It is developed to use in seawater and other chloride-bearing media. It provides good resistance to general corrosion. SMO 254 Round Bar composed of 20 % of chromium and 18 % of Nickel. They are annealed in the temperature ranges of 1150 - 1200 degrees celsius, followed by cooling in water. The 254 SMO Round Bar has a tensile strength in the range of 675 - 850 MPa and yield strength of 310 MPa at room temperature. When hot worked it gives elongation equivalent to 35 %. It has good strength at cryogenic temperatures and does not lose its properties at -196 Fahrenheit. SMO 254 Welding Rod meets the European standards EN 13445-2 as it works in high temperatures between 600 - 1000 Celsius. However, exposing them to these temperatures for a long develop stress as at 400 celsius its yield strength becomes 160 MPa.

A276 6mo UNS S31254 Rod is used in desalination plant equipment and flue gas desulphurization units. UNS S31254 supports cold forming and may be used without re-annealing upto 120 Celsius. It has a modulus elasticity of 196 GPa and minimum tensile strength of 98 Ksi. It is equivalent to DIN 1.4547 Square bar has a moderate density of 8.02 g/cm3 and a specific heat capacity of 464 J/kg - K at room temperature, thus suitable for the paper and pulp industry. It also has a high melting point similar to Alloy 254 flat bar which is equivalent to 1360 to 1405 degrees celsius. Moreover, it has a thermal conductivity of 12.3 W/m - K. This makes it useful in chemical processing industries.

The austenitic stainless steel 6 Moly 254 SMO hex bar has a high level of molybdenum and nitrogen to provide high resistance against crevice corrosion. It is nearly equivalent to Alloy 316L.
