Duplex 2304 – Acid resistant stainless steel

Estimated read time 2 min read

Duplex 2304 stainless steel is acid resistant and has a special ferritic-austenitic structure. It is referred to as Duplex 2304 structural steel, because it is from this steel that parts used in various industries are produced. It retains all its properties during heat treatment. It is characterized by the fact that it is very resistant to stress corrosion. Acid resistant and stainless steel retains its strength during processing, which is why it is willingly used in many different branches of industry.

1.4362 – What is this?

It is a type of stainless steel, which is acid-resistant and has resistance to intergranular and stress corrosion, making it a very convenient material during machining. It does not lose its original properties during welding. Compared to other steel grade 316 L, 1.4404, it is a much better product to work with. In addition, it can be treated as a substitute for steel 1.4460 X3CrNiMoN27-5-2.

Application and properties of steel 1.4362

This type of steel has very high mechanical properties and very good resistance to intergranular corrosion after welding. The steel grade 1.4362 is primarily used in the petrochemical, fuel, chemical, nitrogen, aerospace, construction, energy, paper and cryogenic industries. Duplex 1.4362 is a better grade material with a higher chromium, carbon and molybdenum content in the composition and a lower nickel content than standard S32304 steel. The most common forms of steel are rods, sheets and pipes, which are used in the manufacture of chemical tanks, sleeves, shafts, valves, mixers, desalination systems, flanges, pipelines and radiators and equipment for the construction of aircraft structures.

The mechanical properties of Duplex 1.4362 are primarily its high tensile strength during processing, ranging from 600 to 850 MPa. The yield strength of this steel grade is greater than 400 MPa. The steel can elongate by 25 % during the machining process and its elasticity is equal to 200 GPa. The hardness is less than 260 HB. The supersaturation process should be carried out at 1000 +/- 50℃. Stainless steel X2CrNiN23-4 should be forged and rolled at temperatures from 1000 to 1200℃.
