How environmentally friendly is this new type of steel?

Alan - The immediate reaction from all our commercial people was, "Oh my goodness! That's never going to work. We can't heat things up in a pizza oven - or in a furnace for 2 weeks!" We do do some extended heat treatments, but most of our heat treatments would be less than a day. But Harry's point of, you do all this at pizza oven temperatures is an interesting one. Normally, heat treatment is much higher temperatures than that and both the cost of a pizza oven is relatively low, and the heat loss at that temperature is relatively low, so although you're holding things for a long period of time, the energy loss could actually be a lot less.

Ben - So obviously, it needs quite a long period in order for that structure to evolve, but because it's so much lower temperature, it's altogether a more efficient process.

Alan - It could be, yes.
