Heat-resistant steel - grade 1.4828
GENERAL CHARACTERISTICS
1.4828 - heat-resistant steel intended for loaded parts working up to temperatures around 1050 ℃; austenitic grade with increased resistance to oxidation; commonly used to equip the furnaces
ADVANTAGES
· Excellent resistance to corrosion and oxidation, including aqueous corrosion, high temperature corrosion and Sulphur attacks,
· Maximum temperature of 1050°C in service in the air,
· Very good resistance to carburizing,
· Good weldability and formability.
TYPICAL APPLICATIONS
· Furnace and boilers equipment (esp. supporting parts)
· Annealing and hardening boxes
· Air heaters
· Iron, steel, and non-ferrous industries
· Engineering industry
· Energy conversion plants
· Electrical heating elements
· Cement industry
· Aeronautical engineering
· Automotive exhaust systems
· It is used in the case of high-temperature chimneys, in which the flue gas temperature does not exceed 600 ° C (solid fuel boilers - including fireplaces) and in the case when the combustion temperature is higher than 450 ° C and no liquefaction of condensate - dry chimney.
