Steel Pipe Flange 317 310s/2520 253ma 254smo Stainless Steel Flange Heat Corrosion Resistant

The corrosion resistance of 317 SS is similar to 316 SS, but it is better. The high molybdenum(Mo) content ensures that the overall and local corrosion resistance of 317 is stronger in most media, such as sulfuric acid, acid chlorine and phosphoric acid. In strong oxidizing acids such as nitric acid, 317 is easy to be corroded. The performance of 317L is basically the same as that of 317. Because of the lower carbon content, the welding performance and intergranular corrosion resistance of 317L at high temperature (427-816 ℃) are better than 317.
310S refers to Grade. 2520 is the percentage of content. 2520 (310S) stainless steel is austenitic chromium-nickel stainless steel, which has good oxidation resistance and corrosion resistance. Because of high percentage of chromium and nickel, it has much better creep strength, can work continuously at high temperature, and has good high temperature resistance. When the temperature exceeds 800, it begins to soften, and the allowable stress begins to reduce continuously, with the maximum service temperature of 1200 ℃.
The chemical composition of 253MA is balanced, which makes the steel have the most suitable comprehensive properties in the temperature range of 850 ℃ - 1100 ℃, with extremely high oxidation resistance, oxidation skin temperature up to 1150 ℃; extremely high creep resistance and creep fracture strength; excellent high temperature corrosion resistance and brush corrosion resistance in most gas media; At high temperature, it has high yield strength and tensile strength, good formability and weldability, and enough machinability.
254SMo is an austenitic stainless steel. Because of its high molybdenum(Mo) content, it has high resistance to spot corrosion and crevice corrosion. This brand of stainless steel is developed for use in environments containing halides such as seawater. 254SMo also has good corrosion resistance. Especially in the acid containing halide, the steel is superior to ordinary stainless steel.
