Properties and use of fine-grained steel boiler plates according to EN 10028-3
Boiler plates made of fine-grained stainless steel are distinguished by excellent resistance to high pressure, temperature and corrosion. They are characterized by excellent weldability and low carbon content. Boiler plates made of fine-grained steel, whose technical requirements are specified by regulation EN 10028-3, have guaranteed mechanical properties at low (−50 ℃) and high (400 ℃) temperatures.
Their properties guarantee use even in demanding applications permanently exposed to high temperatures and pressure. Suitable for extremely stressed pressure vessels and equipment. You will use them on boilers, reactors, gas reservoirs and transport containers. They are also suitable for production of condensers, compressors, turbines and where handling of coolants is required. Boiler plates can be used in the chemical, food, pharmaceutical and petrochemical industries or in the field of energy, waste management or the environment.
Choose from a wide range of sizes. We supply sheets in the following dimensions:
- length: max. 18,000 mm,
- width: 1000-3200mm,
