1. Introduction.
1.4835 high temperature refractory stainless steel material is a high-quality austenitic stainless steel with good high temperature oxidation resistance and mechanical properties. Due to its high content of chromium and nickel elements,14835 stainless steel can still maintain good corrosion resistance and mechanical strength in high temperature environments. In addition, the material also has good welding performance and processing performance, and is widely used in high-temperature furnaces, heat treatment equipment, petrochemical and other fields.
Second, the chemical composition.

3. Mechanical properties.
At room temperature, 1The mechanical properties of 4835 high temperature refractory stainless steel material are as follows:
Tensile strength: 620MPa
Yield strength: 310MPa
Elongation: 45%.
Hardness: 220HBW
Fourth, processing performance.
1.4835 high-temperature refractory stainless steel material has good processing performance and can be used for cutting, bending, welding and other processing operations. During processing, it should be avoided to process in the case of severe carbide segregation, which can lead to problems such as cracking. In addition, since the material is sensitive to heat treatment, it should be avoided to stay at high temperatures for a long time so as not to affect the mechanical properties of the material.
Fifth, the field of application.
Since 14835 high-temperature refractory stainless steel material has excellent high-temperature oxidation resistance and mechanical properties, so it is widely used in the following fields:
1.High-temperature furnace: used to manufacture furnace chambers, furnace bottoms, furnace strips and other components, due to its good high temperature resistance, it can ensure the long life and efficient operation of the furnace.
2.Heat treatment equipment: used to manufacture quenching tanks, tempering furnaces, annealing furnaces and other equipment, which can ensure uniform heating and efficient cooling in the heat treatment process.
3.Petrochemical industry: used in the manufacture of reactors, heat exchangers, pipelines and other equipment, which can operate stably for a long time in harsh environments such as high temperature, high pressure and corrosion.
4.Aerospace: used in the manufacture of engine parts, fuel lines and other equipment, due to its excellent high temperature resistance and corrosion resistance, it can ensure the safe and reliable operation of aircraft.
5.Other fields: such as metallurgical industry, power industry and other fields are also widely used.
