SCI 21-22 General Catalog

Plate Blanks

A comprehensive stocked range of grades in carbide plate blanks for mold and die materials, as well as carbide rods for drill or reamer materials. ■ Grades ● AF1 Ultra-fine grained Carbide With grains finer than that of conventional grades, an excellent balance of high toughness and high hardness as well as superior edge sharpness is achieved. ● A1 Micro-fine Grained Carbide Micro-fine grained carbide A1 is a best-selling general purpose grade with high wear resistance and toughness. ● Micro-grained Carbide H1 Reliable grade for machining non-ferrous metals. ● Basic Carbide EH10 Highly evaluated grade for general machining of cast iron and exotic alloys. Perfect for drills and reamers. ● KH Series · KH03: Has strength (transverse rupture strength) and hardness similar to A1, with greatly improved chipping resistance that is comparable to ultra- fine grained grades. · KH05: With a higher cemented carbide binder content than KH03, this grade has even greater strength (transverse rupture strength) and chipping resistance.

K

Ultra-fine grained carbide (AF1) is specially developed for the manufacturing of carbide mold parts (punches) with a variety of sizes in stock.
