310S stainless steel: a kind of high-alloy stainless steel. Compared with other types of stainless steel, the 310S base is austenitic chrome-nickel stainless steel, which has a higher proportion of chromium and nickel, so it is more resistant to high temperature and oxidation. Moreover, it can work normally in the environment of 1200 °C, and is more suitable for making furnace components. Considering its outstanding resistance to oxidation, corrosion, acid and alkali, and high temperature resistance, the current application range of 310S stainless steel has been extended to steam turbines. , aerospace, petrochemical, military and other fields.

 

What kind of concept is 1200 °C? To give a simple example: high temperature lava spilled from volcanoes or ground cracks, the temperature is only between 700 ° C ~ 1200 ° C, in other words, 310S stainless steel has enough conditions to retreat in the lava.

 

Such outstanding high-temperature performance makes people see the potential value of this type of stainless steel. In recent years, aerospace technology has been progressing day by day. The aero-engines in the early stage have adopted aluminum alloy, magnesium alloy and high-strength steel. Made of stainless steel and other materials, the stainless steel here refers to the heat-resistant stainless steel type 310S, which is usually used in the wheel and blade of the high-pressure rotor.

 

Of course, until now, due to the need to increase engine thrust and increase the flight speed of aircraft, the use rate of high-tech materials such as titanium alloys, superalloys and composite materials has been greatly improved. It turns out that the performance of 310S stainless steel in heat-resistant materials is at the forefront, and it is expected that it will gradually expand its application fields in the future and become the mainstream of heat-resistant materials step by step.
