Product Details

JIS G3462 STHA22 Alloy steel boiler and heat exchanger tubes

We also offer steel fabrication service where steel plates can go through processings like cutting, welding, bending, machining, pre-coating, pre-lined, beveling, or as you require. Our steel mills have fabricated employees that have 5-10 years of working experience. If you are interested in buying JIS G3461 steel tube products, contact us now for the latest price or check the following table for equivalent steel grade of JIS G3462.

JIS G3462 specifies the alloy boiler steel tubes used for exchanging heat on the inside and outside of the tube, with 8 steel grades from STBA12-STBA26, it has the similar application as JIS G3461, steel tube of this specification could be supplied as U tube. However, it is not applicable to the steel tubes for heating furnaces and those for heat exchangers of low-temperature service. For final product, heat treatment of the bent portion is not usually performed. However, if there is a request from the orderer, agreement on heat treatment. Joyruns is an experienced boiler and pressure steel tube supplier which can offer you JIS G3462 steel tubes of all grade and dimension range.
