Product Introduction

GB/T 5310 20G boiler steel tube is GB/5310 GB steel grade (foreign corresponding grade: Germany st45.8, Japan STB42, US SA106B), which is the most commonly used steel for boiler steel pipe. Its chemical composition and mechanical properties are basically the same as those of 20 plates.

GB/T 5310 20G boiler steel tube has certain normal temperature and medium-high temperature strength, low carbon content, good plasticity and toughness, and good cold-hot forming and welding performance.

By replacing GB/T 5310 20G boiler steel tube, it can reduce the wall thickness, reduce the amount of materials, and improve the heat transfer of the boiler. Its use position and use temperature are basically the same as GB/T 5310 20G boiler steel tube, mainly used for water wall, economizer, low temperature superheater and other components with working temperature below 500 °C.

BBN is a professional GB/T 5310 20G boiler steel tube, we have our own factory to produce the GB/T 5310 20G boiler steel tube. If you have any need of GB/T 5310 20G boiler steel tube, please contact BBN. We can supply the high quality GB/T 5310 20G boiler steel tube for you.
