Alloy 254 SMO has a Tensile Strength of 680 MPa (98600 psi) and a Yield Strength of 300 MPa (43500 psi). The Poisson’s Ratio of Alloy 254 SMO is 0.30. The Modulus of Elasticity of Alloy 254 SMO is 28300 ksi (195 GPa). Today, because of the huge demand for Alloy 254 SMO in many application areas all over the globe, it is possible to find many 254 SMO material suppliers. But before buying from any of them, you need to ensure that the seller is a reputed one.
Alloy 254 SMO material are used by capacity and transportation units of commercial ventures. Such products are also used in paper machines, tanks and mash and paper digesters. The Elongation at Break of Alloy 254 SMO is 50%. Alloy 254 SMO has a Thermal Conductivity of 97.2 BTU in/hr.ft².°F (14 W/mK). Alloy 254 SMO has a Shear Modulus of 75 GPa (10900 ksi). Annealing of Alloy 254 SMO needs to be done at 2100-2200 °F (1149-1204 °C) and this has to be followed by a water quench.
Alloy 254 SMO has a Brinell Hardness of 210. 254 SMO material is a combination of copper and nickel, with a high content of molybdenum. As such, Alloy 254 SMO finds excellent use in applications areas where there could be chloride stress corrosion cracking, such as in areas like dying operations, marine situations, shut circle water frameworks, saline water and certain applications used in the preparation of nourishments.
254 SMO 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. 254 SMO can provide excellent resistance to stress corrosion cracking allowing tube cold formingand may be used without the necessity to re-anneal at testing up to 120°C.
254 SMO grade is considered a very high end austenitic stainless steel; mainly comprised of between 19.5% and 20.5% chromium, 17.5% to 18.5% nickel, 6% to 6.5% molybdenum and .18% to .22% nitrogen. These specific levels of Cr, Ni, Mo, and N in this “super austenitic” chemical makeup allow 31254 to combine impact toughness resistance to corrosion cracking, with pitting and crevice corrosion resistance. The result is strength of nearly twice that of 300 series stainless steels.It is also characterized by high ductility and impact strength. With high levels of chromium, molybdenum, and nitrogen, Alloy 254 SMO is frequently used in high chloride environments, such as brackish water, seawater, pulp mill bleach plants, and other chloride process streams.
