Stainless Steel 254 SMO Tubes

The alloy 254 SMO tubes are basically stainless steel that has a higher content of molybdenum. It got combined with copper and nickel which gives it a blend of decent imperviousness and hole erosion, in situations that contain halide particles such as bromide, chloride, and fluoride arrangements. S31254 SMO Seamless Tubes is high alloy austenitic steel tubes that are available in different shapes, sizes, custom sizes as per client request. It offers SMO tubes in all forms for wide application usage. The high-quality Tube is thus made using international and national standards. This product has been selected for some special type of industries like gas and oil, petrochemical industry, and marine.
The high content of molybdenum of tubes lead to improved oxidation rate and the result is a rough surface finish. The tubes possess good weldability and are substantially stronger compared to austenitic grades. It can be easily characterized by impact strength and high ductility. The tubes got established with cost effectual substitute with titanium for additional nickel alloy.

Features

The 254 SMO stainless steel Tubes exhibit exceptional resistance toward warm seawater and chloride attack. It is best known for outstanding oxidation resistance. Both seamless and welded tubes can withstand high pressure and high mechanical stress. It can even work in corrosive environments and high temperatures. It got formed using solid metal billet drawing over rod piercing so as to create hollow tubes.
SS 254 SMO tubes don’t require any pre-heat and post weld heat conducts. One more quality of it is that it is imperiled so as to hot cracking controllably for weldment. Meanwhile, hardening of the grade is done through thermal treatment. On the other hand, stainless steel SMO structural constancy is collapsed during the soaring temperature beyond 400 Degree C. It needs to be canned after the cold working so as to attain maximum cracking resistance at severe atmosphere. Other known applications are seawater cooling procedure, sulphuric acid treating plant and oil refinery parts.
We offer stainless steel tubes in a wide range of dimensions, schedules, wall thickness, types, form, end, and length. The length can be double random, cut length, and single random.
