Manifold - Model SMO 254 -Round Bar

A high pitting resistance number indicates that the stainless steel grade has a high resistance to localized corrosion like pitting.The stainless steel is considered to be a very high end grade due to its higher strength as compared to other conventional austenitic stainless steel grades.The 6mo UNS S31254 Bar has good weldable properties.

Alloy 254 SMO Bar is mainly comprised of 19.5% and 20.5% chromium, 17.5% to 18.5% nickel, 6% to 6.5% molybdenum like standard austenitic stainless steel grades. But unlike convention austenitic stainless steel grades, the ASTM A479 UNS S31254 contains about 0.18% to 0.22% nitrogen. The specific levels of Chromium, Nickel, Molybdenum and Nitrogen in its super austenitic 1.4547 Round Bar chemical makeup allows the SMO 254 Welding Rod to combine its impact toughness resistance to corrosion cracking, with pitting and crevice corrosion resistance. The result is strength of the 254 SMO Rod nearly twice that of 300 series stainless steels.

The UNS S31254 or the SMO 254 Round Bar is often referred to as a “6% Moly” grade due to the content of molybdenum. The 254 SMO Round Bar has the ability to withstand high temperatures while maintaining its high strength under volatile conditions. This grade is used successfully in various applications such as Flue gas desulfurization and Chemical environments. Other applications of the 6mo UNS S31254 Bar include Chemical processing equipment, Flue gas desulfurization scrubbers, Desalination equipment, Seawater handling equipment, Food processing equipment, Heat exchangers, Hydrometallurgy, Pulp mill bleach systems, Tall oil distillation columns and equipment & Oil and gas production equipment.
