HN radiant tubes for furnaces are manufactured by centrifugal casting technique at LAWAI INDUSTRIAL CORPORATION in Taiwan. 
HN is the heat-resistant alloy suitable for using under high temperature environment. Centrifugal casting technique is the right manufacturing method to produce the radiant tubes for furnaces because the tubes are one-piece construction.  Bending or deformation will not happen when using the HN radiant tubes produced at LAWAI in the high temperature condition for a long time (The lifetime of the radiant tubes could be longer than 5 years).  
If you are looking for the HN radiant tubes for furnaces that are with long lifetime and long durability under high temperature, LAWAI’s custom radiant tubes will be the best choice!
