Origin of Product:
Otokumpu, Sweden
Standard:
ASTM A240/ASME SA-240、ASTM A276、ASTM A182/ASME SA-182、ASTM A312/ASMES A312
Main Chemical Compositions:
C:0.05~0.10
S:≤0.03
Ni:10.0~12.0
Si:1.4~2.0
Cr:20.0~22.0
N:0.14~0.20
Ce:0.03~0.08
Physical Properties:
Density of 253MA (S30815):7.98g/cm3
Mechanical Properties:
Tensile Strength: σb≥650Mpa
Yield Strength: σb≥420Mpa
Elongation:δ≥40%
Corrosion Resistance:
253MA is an alloy obtained by increasing the nitrogen content and adding rare earth elements for micro-alloying on the basis of alloy 1.4828, which has good oxidation resistance, good resistance to high temperature corrosion, and good high temperature mechanical strength. The most suitable use temperature range is 850-1100℃ , if used in the range of 600 to 850℃, the impact toughness at room temperature will be reduced due to structural changes. The chemical composition of 253MA is balanced, which makes the steel have the most suitable comprehensive performance in the temperature range of 850℃-1100℃, very high oxidation resistance, starting oxidation temperature up to 1150℃; very high creep type change resistance and creep fracture strength; good resistance to high temperature corrosion and balance brush corrosion resistance in most gas media.
Application:
253MA is widely used in sintering equipment, blast furnace equipment, steel melting, furnace and continuous casting equipment, rolling mills (heating furnaces), heat treatment furnaces and accessories, mineral equipment and cement production equipment.
