DIN1.4835 253MA UNS S30815 Austenitic Stainless Heat resistant Steel

The chemical composition of 253 ma is balanced, make the steel at 850 ℃ to 1100 ℃ temperature range has the most appropriate comprehensive performance, high resistance to oxidation, the oxidation of skin temperature as high as 1150 ℃;Extremely high variant variable capacity creep and creep rupture strength;In most of the gas medium has good resistance to high temperature corrosion and scale brush resistant ability;Higher yield strength and tensile strength at high temperature.Good formability and weldability, and enough to machinability.

Besides element chromium and nickel alloy, 253 ma stainless steel also contains a small amount of Rare Earth Metals, Rare Earth Metals, REM), so as to significantly improve its oxidation resistance.Nitrogen added to improve the creep properties and make this be fully austenitic steel.In spite of chromium and nickel content is relatively low, but this kind of stainless steel have many cases with high alloyed steel and nickel base alloy high temperature properties of the same.

Mass fraction in % according to DIN EN 10088-3 Abbreviations: C = carbon, Cr = chromium, Cu = copper, Mn = manganese, Mo = molybdenum, N = nitrogen, Ni = nickel, P = phosphorus, S = sulphur, Si = silicon, Ti = thallium.

Physical properties

Magnetisability: none Density (kg/dm³): 7.8 Thermal conductivity (at up to 20°C): 15 Electronic resistance at room temperature (in Ω mm²/m): 0.85

Mechanical properties

Yield strength Rp0.2 MPa min.: 310 Tensile strength Rm MPa: 650-850 Elongation at break A80 % min.: 37 The mechanical properties (transverse) correspond to the specifications according to DIN EN 10095. Welding CEV calculator The material 1.4835 has good welding properties and can be used with all common welding processes such as arc welding, metal inert gas welding (MIG welding) or tungsten inert gas welding (TIG welding). Preheating and post-weld heat treatment are not normally required. You can use the CEV calculator to determine the carbon equivalent of the steel. Heat resistance Stainless steel AISI 253 MA / 1.4835 is a steel grade designed for heat resistance, which is specially intended for high-temperature applications. Heat resistance is given up to approx. 1150 °C. The material also has good scale resistance, which is given in air up to 1100 °C, but decreases from around 900 °C. Corrosion resistance Due to the high carbon and nitrogen content, stainless steel 1.4835 / AISI 253 MA has reduced resistance to oxidising and reduced sulphur-containing gases. Corrosion resistance in contact with water is not given. Heat treatment and hot forming Solution annealing (cooling with air or water): 1020-1120 °C Hot forming (cooling by air): 1150-900 °C

Application area of stainless steel AISI 253MA / 1.4835

Our products have been used in all kinds of areas, such as aviation,aerospace,navigation,nuclear energy,chemical industry,electronic information,achine manufacture, petrochemical, automotive,instrument and meter, Communication ,transportation, and medical instruments, etc.
