IBR Boiler Tubes, IBR Seamless Pipe Material, IBR Tube
As an aside, all hot forming and shaping employed to make boiler tubes and piping is done in the austenite temperature range of 1650 o F to 2000 o F. With the continued cooling, the face-cantered-cubic austenite begins to transform to body-centered-cubic ferrite at a temperature of around 1600 o F, and again, the exact temperature depends on the composition.
