CHEMICAL COMPOSITION. Results of the purity test will be rounded to the nearest whole percentage point (0.5 rounded up). A deduction of $1.00 (one dollar) per ton will be made for each percentage point from ninety-four percent (94%) through ninety percent (90%) and $2.00 (two dollars) per ton for each percentage point from eighty-nine percent (89%) through eight-five percent (85%). Material with purity less than eighty-four point five percent (84.5%) will be paid for as snow and ice abrasives at a rate of $4.00 (four dollars) per ton.
CHEMICAL COMPOSITION. Total chlorides expressed as NaC1 shall be a minimum of 95%
CHEMICAL COMPOSITION. Sodium Chloride
CHEMICAL COMPOSITION. The sodium chloride shall conform to a chemical composition of a minimum of 95%. Variations of less than 95% but above 93% will result in acceptance at reduced payment as provided in Section III, Penalties and Price Adjustments. .
CHEMICAL COMPOSITION. Mechanical properties Rockwell C hardness measured in accordance with ISO 6508-1:2005. In each case the measurements must be made on samples taken from the actual brake disc or drum.
CHEMICAL COMPOSITION. Microstructure The microstructure must be characterised in accordance with ISO 945-1:2006

CHEMICAL COMPOSITION. The supplied steel shall conform to the chemical composition presented in Table 4-4, unless otherwise modified as approved by the Employer’s Representative. The ladle analysis of the steel shall be carried out by the method specified in relevant parts of IS 228 or any other established international standard. However, where the method is not given in IS 228 and its relevant parts, a suitable method shall be adopted as agreed between the Employer’s Representative and the Contractor. The product analysis shall be carried out on the finished plates. Carbon (C) 0.20 0.02 Manganese (MN) 1.3 0.04 Sulphur (S) 0.04 0.005 Phosphorus (P) 0.04 0.005
1. Carbon Equivalent (CE) = C + Mn/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15 2. CE based on ladle analysis shall be 0.45 as per IS 3589 3. The minimum Si in silicon kilned steel shall not be less than 0.10%. When the steel is Al/Al-Si kilned, the requirement regarding minimum silicon content need not apply. 4. When micro-alloying elements like Nb, V and Ti are used individually or in combination the total content shall not exceed 0.2%. Copper may be present between 0.20 to 0.35 percent as mutually agreed to between the Contractor (and manufacturer) and the Employer’s Representative. The copper bearing quality shall be designated with a suffix Cu, for example, Fe 410 Cu + WA. Nitrogen content of the steel should not exceed 0.012%, which shall be ensured by the Contractor (or manufacturer) by inspection analysis.
