Product Description
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 G3462 Grade STBA 12 Tubes have a minimum yield strength of 205 Mpa.
