SMO 254 Tubes Manufacturer

Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality SMO 254 Tubes which are highly alloyed and have a corrosion resistance comparable to high performance austenitic steel. These SMO 254 Seamless Tubes does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain – proof in low – oxygen, high – salinity, or poor air – circulation environments. The basic idea of these SMO 254 Welded Tubes is to produce a chemical composition that leads to an approximately equal mixture of ferrite and austenite.

There are various sizes, shapes and surface finishes of SMO 254 EFW Tube to suit the environment of the alloy that must endure. These SMO 254 ERW Tube is used where both the properties of steel and corrosion resistance are required. By lowering total material weight, you also lower transportation and assembly costs, reducing environmental impacts even further – making SMO 254 Round Tubes a genuine material of the future.

The high chromium and molybdenum content also gives these SMO 254 Square Tubes a high resistance to acids that could cause pitting. SMO 254 Rectangular Tubes is 22 % chromium (austenitic / ferrite) steel with moderate / good strength and good general corrosion/ stress corrosion cracking resistance. These SMO 254 Electropolish Tubes has high performance, high strength, with 25 % chromium (austenitic / ferrite) steel strands and wire ropes with outstanding corrosion resistance.
