This is a pricing table for chemical commodities organized by elemental composition and weight percent ranges across six product classes.

The table lists chemical elements including Carbon, Manganese, Phosphorus, Silicon, Nickel, Chromium, Molybdenum, Vanadium, Copper, Titanium, Aluminum, Boron, Silicon (secondary listing), Zanthanum, and Zirconium. For each element, percent maximum limits are established across Classes 1 through 6, with Class 1 representing the most stringent requirements and Class 6 the least restrictive. The percent ranges vary significantly by element and class; for example, Carbon ranges from 0.28 percent in Class 1 to 0.45 percent in Class 5, while Manganese ranges from 0.15 to 0.20 percent across classes. Most trace elements in higher classes show dashes, indicating no specified limits. The document includes footnotes stating that the percentage of boron and sulphur together shall not exceed 0.01 percent, the chemical content shall be adjusted for set-size and mechanical requirements within classes, and maximum limits on execution are established with any elements intentionally added by the manufacturer shall be reported for each analysis.
