JIS G3461 Carbon Steel Tubes for Boiler and Heat Exchanger Scope:JIS G3461 Carbon Steel Tubes is mainly used for exchanging heat on the inside and outside of the tube, such as water tubes, smoke tubes, superheater tubes, air preheater tubes, etc.Its application fields are: boiler tubes, heat exchanger tubes, condenser tubes, catalyzer tubes, etc. It can also be used in chemical and petroleum industries, But it can't be used for low temperature service. Chemical Composition:

JIS G3462 ALLOY STEEL BOILER AND HEAT EXCHANGER TUBES JIS Specification alloy steel Tubes are used for high temperature service applications. Seamless Alloy Steel Tubes according to JIS G3462 Grade STBA 12 are reheated and furnished in full annlealed,isothermal annealed or normalised quenched and tempered condition. JIS G3462 Grade STBA 12 Alloy Steel Seamless Tubes have a typical chemistry with additions of 0.45-0.65 Molybdenum.Bearing minimum tensile strength of 380 Mpa JIS
