XV, <br />a. The cutting edges shall be formed from high carbon steel made by the open <br />hearth, basic oxygen, or electric furnace process and shall have the following <br />composition. <br />b. The composition of steel shall be as follows: <br />Hi h Carbon <br />Heat Treated <br />m <br />Com osition <br />Min % <br />Max % <br />Com osition <br />Min % <br />Max <br />Carbon <br />0.80 <br />1.00 <br />Carbon <br />0.25 <br />0.35 <br />Manganese <br />0.50 <br />0.90 <br />Manganese <br />0.75 <br />1.20 <br />Phosphorous <br />--- <br />0.05 <br />Phosphorous <br />--- <br />0.05 <br />Sulfur <br />--- <br />0.05 <br />Sulfur <br />--- <br />0.05 <br />Silicon <br />--- <br />0.35 <br />Silicon <br />0.10 <br />0.40 <br />EE <br />Boron <br />0.0005 <br />0.0085 <br />c. The finished cutting edge shall have a Brinell hardness number, under a 3000 <br />kilogram load, of not less than 250 nor more than 350 for high carbon blades, and <br />not less than 400 nor more than 520 for heat treated blades. The Brinell hardness <br />number will be determined by the current Method Test for Brinell Hardness of <br />Metallic Materials, ASTM Designation E10. <br />d. A chemical analysis of each melt of steel shall be made available by the <br />manufacturer to determine the percentages of the elements specified. <br />3. The cutting edges shall be of the length specified on the request for quotation form <br />and shall be double bevel, curved, 5/8 inch or 3/4-inch-thick, and 6 inch or 8 inch <br />wide after forming. The bevel shall be 1 inch in length and the cutting edge shall have <br />a radius curvature of 7 1/2 inch to 10 inch. The finished blade section will be given a <br />coat of rust resistant paint and shall be free of warpage and longitudinal deviation. <br />The cutting edges for 5/8-inch blades and 3/4-inch blades shall be punched with <br />11/16-inch square holes with countersink to receive 5/8-inch diameter #3 plow bolt. <br />Hole punching to be "standard highway punch" (end 2 holes on each end of the blade <br />on 3-inch centers, and the remaining holes 12-inch spaced center to center across <br />the middle of the blade) as per the diagram below. <br />LENGTH (A:S SPECIFIED ON RrOUEST FOR <br />3" , 3" <br />3" 1 3" <br />---------- ____ ___.n. .. . _.....a __m__.0____m.__ .._ __._.. .. ...i3__.._.. -. ___.._______..m.. <br />50 � <br />DIVISION H: SNOW REMOVAL MATERIALS CONT'D <br />A.
