DIN17175 13CrMo44 Cold drawing seamless heat exchanger tube
13CrMo44 steel tube is mainly used for a high-pressure boiler system. World iron&steel offers 13CrMo44 boiler tubes in various sizes and specifications. If you are looking for this material, please contact us or get a quote! Not only do we have all kinds of sizes, we also have all kinds of sizes that are hard to find.
13CrMo44 alloy steel tube is used in the heating surface pipe with low and medium pressure boilers (operating pressure is generally not greater than 5.88mpa and operating temperature is below 450℃). The addition of Nickel and Chromium makes 13CrMo44 steel tube with high mechanical performance and corrosion resistance, which is used for heating surface pipes, coal economizers, superheaters, reheaters, petrochemical industry pipes and so on in high-pressure boilers (working pressure is generally above 9.8Mpa and the working temperature is between 450℃ and 650℃).
