Corrosion Resistance
Alloy Composition and Properties
253MA is an enhanced alloy derived from alloy 1.4828. It is achieved by increasing the nitrogen content and incorporating rare earth elements for micro - alloying. This results in:
Good oxidation resistance
Good resistance to high - temperature corrosion
Good high - temperature mechanical strength
Temperature - Related Performance
Very high oxidation resistance, with a starting oxidation temperature as high as 1150℃
Very high creep - type change resistance and creep fracture strength
Good resistance to high - temperature corrosion and balanced pitting corrosion resistance in most gas media
Optimal Use Temperature Range
The ideal temperature range for 253MA is 850 - 1100℃. Within this range, it exhibits the most suitable comprehensive performance, including:
Lower Temperature Range Consideration
If used in the range of 600 - 850℃, the impact toughness at room temperature may be reduced due to structural changes.
Applications
253MA finds extensive use in various industrial equipment and processes, including:
Sintering Equipment
Used in sintering furnaces and related systems.
Blast Furnace Equipment
Components and structures of blast furnaces benefit from its high - temperature properties.
Steel Melting, Furnace and Continuous Casting Equipment
Crucial in the steel production process, particularly in areas exposed to high temperatures.
Rolling Mills (Heating Furnaces)
Essential for heating furnaces in rolling mills where high - temperature stability and corrosion resistance are required.
Heat Treatment Furnaces and Accessories
Ideal for heat treatment applications due to its ability to withstand high temperatures and resist corrosion.
Mineral Equipment
Used in equipment for mineral processing where high - temperature and corrosive environments are common.
Cement Production Equipment
Valuable in cement manufacturing processes, especially in high - temperature kilns and associated systems.
