What are SMO 254 Bars?

SMO 254 bars are high-alloy austenitic stainless steel bars known for their exceptional corrosion resistance in aggressive environments, such as seawater and acidic solutions. They contain significant amounts of chromium, molybdenum, and nitrogen, offering superior resistance to pitting, crevice corrosion, and stress corrosion cracking. SMO 254 bars are widely used in industries like chemical processing, marine engineering, and oil and gas production due to their excellent mechanical properties and reliability in demanding conditions.

Manufacturing Process Of SMO 254 Bars

Melting

The first step in the process is melting raw materials in an electric furnace. These raw materials are typically iron ore, chromium, nickel, and other elements in exact amounts.

Casting

After melting, the metal is put into molds to form slabs or billets. The processing of these first forms is then continued.

Hot Rolling

After being heated, the billets are shaped into long, thin rods by going through a series of rolling mills. Because the metal is heated above its recrystallization temperature during this operation, it is known as hot rolling.

Annealing

After that, the rods are annealed to reduce stress and enhance machinability. In order to do this, the rods must first be heated to a certain temperature and then gradually cooled.

Cutting

Lastly, shearing machines or other cutting techniques are used to cut the rods to the required length.
