Instrument of the bimetallic thermometer is used SS304 stainless steel, steel grade 0 cr18ni9, take a look at some other stainless steel under the temperature range. Category steel grade and its main use iron grain size range of applicable temperature 00 cr12 ( 410 l) Oxidation temperature of 600 ~ 700 ℃, used for high temperature and high pressure valve, burner 0 cr13al ( 405). Suitable temperature range of 700 ~ 800 ℃, the gas turbine compressor blade 1 cr17 ( 430). Under 900 ℃ temperature oxidation resistance, used for furnace with high temperature parts, nozzle markov size 1 cr12 ( 403). In 600 ~ 700 ℃ temperature range has a certain high temperature oxidation resistance and high strength, can be used for steam turbine blades, nozzle, boiler burner high temperature valve parts 1 cr13 ( 410). Oxidation temperature of 700 ~ 800 ℃, its purpose is the same as 1 cr12 steel austenite size 0 cr18ni9 ( 304). 1 cr18ni9ti oxidation temperature below 870 ℃, can be used as boiler heating surface pipes, heating furnace parts, heat exchanger, muffle furnace, converter, nozzle 0 cr18ni10ti ( 321). 0Cr18Ni11Nb（ 347). In 400 ~ 900 ℃ temperature range high-temperature oxidation and corrosion resistance can be used to working temperature below 850 ℃ of pipe 0 cr23ni13 ( 309S) Oxidation temperature to 980 ℃ for burner fire tube, turbine blade, heating furnace, the methane conversion device, the high temperature 0 cr25ni209 separation device ( 310S) Oxidation temperature to 1035 ℃, used for heating furnace parts; Working temperature below 950 ℃ of gas transmission system components 0 cr17ni12mo2 ( 316). 0 cr19ni13mo2 oxidation temperature is not lower than 870 ℃ temperature of 600 ~ 750 ℃ in the chemical industry, oil refining heat exchanger pipe, furnace tube type precipitation hardening 0 cr17ni7al ( 631). Working temperature below 550 ℃ high temperature bearing components
