STB35 belongs to the carbon steel grade specified in JIS G3461. It is categorized as a low carbon steel grade suitable for use in boiler and heat exchanger applications.
Application
JIS G3461 STB35 carbon steel tubes find application in various industries, primarily in the manufacturing of boilers and heat exchangers. They are specifically designed to transfer heat efficiently in these systems. STB35 tubes are commonly used in power plants, petrochemical plants, refineries, and other industrial facilities where heat exchange processes occur.
While STB35 is a popular choice, there are alternative grades available that may suit specific requirements. Some possible alternative grades for carbon steel tubes in boiler and heat exchanger applications include STB33, STB42, and STB52. These grades may offer different mechanical properties or chemical compositions to cater to different operational conditions or design considerations. Consulting with technical experts or referencing industry standards can help in selecting the most suitable alternative grade for specific applications.
