What is 254SMO stainless steel？

It was originally developed for use in corrosive environments such as seawater and other halides, and is particularly suitable for fields such as seawater treatment and flue gas desulfurization

What is the application field?
Due to its excellent corrosion resistance and high strength, 254SMO stainless steel is widely used in the following fields: chemical, food, pharmaceutical, petroleum, construction, kitchenware, tableware, vehicles, household appliances

 

What are the requirements for processing and welding?
Due to the high work hardening rate of 254SMO stainless steel, sharp tools and low-speed cutting are required during processing to ensure good machining results. Filler materials such as AWS A5.14 ERNiCrMo-3 and alloy 625 are required during welding to ensure the strength and corrosion resistance of the welded joint

 

What is the difference between SMO 254 and ss316?

Although both 254 SMO and 316 stainless steel have excellent corrosion resistance, 254 SMO stands out due to its outstanding corrosion resistance, strength, toughness, and heat resistance, especially in harsh environments

 

How to weld 254 type SMO stainless steel?
For super austenitic stainless steel (254 SMO), the heat input during welding should not exceed 1.5 kJ/mm, and the interlayer temperature should not exceed 100 ° C (210 ° F) in multi pass welding
