Yieh United Steel Corp. (YUSCO) has reported that it has boosted its output of products that do not use nickel by 20% and plans further increases as nickel costs soar, joining a global trend of substitution and production cutbacks as prices for nickel are at record levels. As per report, YUSCO has increased production of 400 series stainless steel, which does not use nickel, to 15,000tns per month from 5000tns per month. The official said that YUSCO plans to lift non-nickel stainless or low nickel products to around 25% of its monthly 80,000tn output with the amount of stainless steel containing nickel being reduced.
