SteelOrbis has learned that spot market prices for US domestic plate are now being heard in the range of $31.00-$32.00 cwt ($683-$705/mt or $620-$640/nt), against $30.50-$31.50 cwt. ($672-$694/mt or $610-$630/nt), ex-mill, a week ago. The uptick in prices, souces note, is linked to plate mills' desire to firm prices alongside other flat rolled steel products. Demand, however, remains unexciting.
