Melting Process5.1 U
39、nless otherwise specified in the individual product specification, the steel shall be fully killed. Use of the basic oxygenprocess shall be limited to grades containing less than 6 % chromium.5.2 If a specific type of melting is required by the purchaser, it shall be stated on the purchase order.5.3
40、 The primary melting may incorporate separate degassing or refining and may be followed by secondary melting such aselectroslag remelting or vacuum remelting. If secondary melting is employed, the heat shall be defined as all of the ingot remeltedfrom a single primary heat.5.4 Steel may be cast in i

The steel producer shall remove the transition material by an established procedurethat positively separates the grades. Should the purchaser deem it
42、 necessary to have the transition zone of two heats of the samegrade which are continuously cast discarded, the purchaser shall invoke Supplementary Requirement S53.5.5 QualityThe steel producer quality control procedures shall provide sufficient testing of carbon and alloy steels inaccordance with
