Main material of tubes erosion shields

Different types of stainless steel are selected according to the specific conditions of different working conditions. Common materials are: TP321 (Cr18Ni9Ti), TP309S (Cr23Ni13), 1Cr20Ni14Si2, TP310S (Cr25Ni20), 1Cr25Ni20Si2, and some low temperature areas (such as low temperature superheater, low temperature reheater) are made of 1Cr13, 1Cr6Si2Mo and other materials.

The boiler was originally designed to be accurate. Different materials have different temperature resistance and mechanical strength. 1Cr13, 1Cr6Si2Mo generally has a temperature resistance of 600 ℃ or less.

304 stainless steel Erosion Shields

Grade 304 stainless steel is the most versatile and the most widely used of all stainless steels.

309 stainless steel Erosion Shields

CS 309 is a highly alloyed austenitic stainless steel used for its excellent oxidation resistance, high temperature strength and creep resistance.

310S stainless steel Erosion Shields

Grade 310S is a lower carbon version, less prone to embrittlement and sensitisation in service.

316L anti corrosion and anti wear steel erosion shields

Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.
