Operating costs for flat-rolled mini-mill producers have dropped in 2019 as weaker steel markets have pulled down metallics prices. This has meant that operating costs for mini-mills are now in line with integrated producers in the USA. However, the current cost level is not expected to be maintained. US mini-mills are typically higher cost.

The test is done by measuring the surface area of the indentation created by a diamond in the shape of a square-based pyramid. The HV number equals the force divided by the area (F/a). Carbide grades are usually in the range of 1,300-1,900 HV. Ceramics can reach a hardness of 2,000 HV, CBN up to 3,000 HV, and PCD up to 6,000 HV.
