HK / JIS SCH21
inquiry
Material :
A297 HK / EN 1.4848

Heat-resistant alloys were designed for casting manufacturing methods.  And centrifugal casting is one of the techniques good for producing HK / SCH21 / 1.4848 heat-resistant steel tubes and rings. 
The straight radiant tubes produced by centrifugal casting are one-piece construction with fine structures and non-porosities. The centrifugally cast straight radiant tubes perform the extraordinary stable and long lifetime in high temperature environment. 
Low quantity order of the straight radiant tubes is possible by centrifugal casting technique.  Each tube is manufactured by LAWAI team in Taiwan. 
Give yourself an opportunity to know more about us.
We believe the straight radiant tubes made in Taiwan will perform the best in your applications!
