Historical Process

It is said that wars and military forces propel human technology forward, and every war may bring about technological innovation. High temperature resistant stainless steel pipe first applied to the military was in the First World War, the use of each other to make the barrel easy to heat, a fever and air oxidation-rust, and easy to wear, the war is very unfavorable, so scientists have struggled to study, and finally invented stainless steel to make the barrel, achieved good results, This is the original 310S stainless steel tube, the initial high-temperature stainless steel barrel.

Stainless Steel 310S Spot Performance Requirements

? oxidation resistance

? thermal strength

The antioxidant resistance is the ability of the heat-resisting steel to endure in the high-temperature condition without forming or not being eroded by the medium. Thermal strength means that the spot of the steel tube still has a certain strength under the high temperature without producing a lot of deformation and breaking.

As the 310S stainless steel tube has the above properties depending on its internal alloying composition, the antioxidant resistance is affected by the factors: 1, in general, adding CR, Al, Si, ni and other elements can improve their antioxidant resistance, considering the addition of Al and Si will cause the brittleness increase of steel, so al, Si only as an auxiliary element , and CR is the main addition element; 2, 310S stainless steel tube in spot the CR content should be added to the working temperature of the workpiece, and the higher the working temperature of the spot of the steel pipe, the more CR required to join.

310S Material Performance

310S Stainless steel is austenitic chromium nickel stainless steel with good oxidation resistance, corrosion resistance, because a higher percentage of chromium and nickel, so that has a good many creep strength, at high temperature can continue operation, with good temperature resistance, temperature of more than 800, start to soften, Xu use stress began to continue to reduce, Maximum operating temperature 1200 ?. Because Nickel (NI), chromium (CR) content is high, has the good oxidation resistance, corrosion resistance, acid and alkali resistance, high temperature performance, high temperature steel pipe for the manufacture of electric heaters and other occasions, austenitic stainless steel to increase the content of carbon, because of its solid solution strengthening effect to enhance the strength, austenitic stainless steel chemical composition characteristics of chromium, Nickel as the basis for the addition of molybdenum, tungsten, niobium and titanium elements, because of its microstructure as a surface-centered cubic structure, so at high temperature has high strength and creep strength.
