Comparison of Scrap Charged to Pig Iron Based Steel
Comparison of Scrap Charged to Pig Iron Based Steel
(OP)
Has anyone noticed a difference in performance of steels manufactured from scrap steel as opposed to the traditional method involving pig iron? We have end users of our products saying that the steel is not as good as it used to be. We use more scrap based steel than before, so is there a difference, or is this the case of jumping on the "bad steel" bandwagon.
Also, if you have seen any good articles on this topic please inform me where.
Thanks.

It is not possible to use always pig iron for steel making.
Your customer's comments are similarly echoed by some casting users as follows"Castiron castings made from cupola metal are better than those similarly produced by induction melting"

Chemistry control is much better today, and general steel practice is much more consistent.
The amount of some tramp elements is creaping up (such as Cu). And some important (and expensive) additions are trimmed as low as specs allow.
The same rules as always apply though; 'you don't always get what you pay for, but you never get more than you pay for'.
