Simple description about 310/310s
High temperature resistant stainless steel, also known as 310S (0Cr25Ni20) stainless steel, is austenitic chromium-nickel stainless steel, has good oxidation resistance, corrosion resistance, because a higher percentage of chromium and nickel, so that has much better creep strength, Can continue to work at high temperatures, with good high temperature resistance.
Due to the high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance, high temperature resistance, high temperature resistant steel is specially used in the production of electric furnace tubes and other occasions, carbon in austenitic stainless steel After the content, due to its solid solution strengthening effect, the strength of the austenitic stainless steel is added to the chromium, nickel-based molybdenum, tungsten, tantalum and titanium, due to its face-centered cubic structure. Therefore, it has high strength and creep strength at high temperatures.
Comparison about 310s and 321
310S high temperature, 321 corrosion is quite good in the case of high temperatures or 310S is more suitable for the maximum temperature can reach 1200 °, oxidation resistance, corrosion resistance, acid and alkali, high temperature performance is much better than 321
Comparison about 310s and 316L stainless steel
316L is a molybdenum-containing stainless steel that can be used between 15% and 85% sulfuric acid. (But the material properties will drop in high temperature environment)
The 310S can be used between 15% and 50% sulfuric acid. (Due to its high heat resistance in high temperature environments, material properties will not decrease
Heat resistance, Wear resistance
Because 310S has a higher melting point than 316L, it is more wearable than 316L in high-temperature, high-speed friction environments.
