INCOLOY 28 is a highly alloyed austenitic stainless steel with excellent corrosion resistance and can resist the erosion of various corrosive media. This article will introduce the performance characteristics, application fields and related technical parameters of INCOLOY 28.
Performance characteristics of INCOLOY 28:
INCOLOY 28 is a highly alloyed austenitic stainless steel with excellent corrosion resistance and can resist the erosion of various corrosive media. The main components of the alloy include elements such as nickel, chromium, copper, molybdenum and iron, with the copper content ranging from 0.6-1.4%. The addition of copper can improve the sulfuric acid resistance of the alloy, making it still have excellent corrosion resistance at high temperatures.
The chemical composition of INCOLOY 28 is as follows:
Element | Content
—|—
Nickel | 31.5-35.5%
Chromium | 26-28%
Copper | 0.6-1.4%
Molybdenum | 3-4%
iron | balance
The physical and thermodynamic properties of INCOLOY 28 are as follows:

Application fields of INCOLOY 28
INCOLOY 28 is widely used in the chemical and petrochemical industries due to its excellent corrosion resistance. The alloy can be used to manufacture various chemical reactors, distillation columns, heat exchangers, storage tanks, pipes, valves and other equipment. In addition, INCOLOY 28 can also be used in the manufacture of desalination equipment, offshore platforms, ships and marine engineering and other fields.
The technical parameters of INCOLOY 28 are as follows:
- Heat Treatment: Solution treated at 1050-1150°F (566-621°C) followed by rapid cooling in water.
- Cold working: INCOLOY 28 can be cold worked to increase its strength level. During the cold working process, the strength of the alloy will increase as the amount of cold working increases, but the plasticity and toughness will decrease accordingly.
- Welding: INCOLOY 28 can be welded by TIG, MIG, arc and plasma arc methods. During the welding process, attention should be paid to controlling the welding temperature and welding speed to avoid defects such as cracks and deformation.
- Corrosion performance: INCOLOY 28 has excellent corrosion resistance and can resist the erosion of various corrosive media. The alloy shows excellent corrosion resistance in strong corrosive media such as sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, chloride and oxidants.
