Surface heat treatment methods for hardox 500 welding

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the HARDOX 500 welding steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the HARDOX 500 welding steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.

ASTM A242 is a kind of high strength low alloy steel with good atmospheric corrosion resistance. Some applications show that it HARDOX 500 welding has better corrosion resistance than ASTM A36 steel plate and ASTM a572 50 steel plate. Like weathering steel, it can be used without painting, and corrosion naturally stops and becomes a protective layer.
