Introduction of 310S stainless steel thick wall steel pipe

310s stainless steel thick-walled steel pipe has very good oxidation resistance and corrosion resistance. because it contains a high percentage of chromium and nickel, it has high creep strength and can continue to operate at high temperatures. the working temperature is 1200 ℃, the continuous use temperature is 1150 ℃, has good high-temperature resistance.

overview of 310s stainless steel thick-walled steel pipe:
310s stainless steel thick-walled steel pipe is a kind of stainless steel commonly used in industry. it is also called 2520 stainless steel in the industry. its corrosion resistance is better than 304 stainless steel, but the price is cheaper than 904l stainless steel, so it is widely used in high-heat/high-temperature contact parts, such as exhaust pipes, heat treatment furnaces, heat exchangers, incinerators, etc.

chemical composition of 310s stainless steel (%): ni nickel: 19.00-22.00 cr chromium: 24.00-26.00 si silicon <= 1.50 mn manganese <= 2.00 c carbon <= 0.08 s sulfur <= 0.030 p phosphorus <= 0.035. from the composition, we can see that 310s stainless steel thick-walled steel pipe has good corrosion resistance, acid and alkali resistance, and high-temperature resistance due to its high nickel (ni) and chromium (cr) content. 310s stainless steel thick-walled steel pipe is specially used for furnace components, nozzles, combustion chambers, and other occasions, when the carbon content is increased in austenitic stainless steel, the strength is improved due to its solid solution-strengthening effect. the chemical composition characteristics of austenitic stainless steel are based on chromium and nickel with the addition of molybdenum, tungsten, and niobium. elements such as titanium and titanium have high strength and creep strength at high temperatures due to their face-centered cubic structure.

although this kind of stainless steel is widely used in china, the name "310s stainless steel" comes from the united states. many people think that 310s stainless steel thick-walled steel pipe is a model name in japan, but strictly speaking, the official name of 310s stainless steel in japan is "sus310s".

310s thick-walled steel pipe is a kind of stainless steel with good high-temperature resistance. it is widely used in the production of equipment and parts that require good comprehensive performance (corrosion resistance and high-temperature resistance). to maintain the inherent corrosion resistance and high-temperature resistance of stainless steel, the steel must contain more than 24% chromium and more than 19% nickel. 310s stainless steel is a brand of stainless steel produced by american astm standards. 310s is equivalent to my country's 0cr25ni20 [now changed to 06cr25ni20 according to gb/t 20878-2007] stainless steel.
