Boiler Material - IBLS

The big advantage of the use of this material is the wall thicknesses can be about 1/2 as thick. The material is almost twice as strong as mild steel and no extra thickness allowance need be made to allow for corrosion in the boiler through use. The material they are talking about is ASTM A240, A276, A789 and A790 (depending on the application).
