WebSintered metals should run against fine-grained pearlitic cast iron or alloy irons, Brinell Hardness 180–250. High carbon steel such as EN6 for moderately loaded, and EN42 for heavy-duty thin counterplates in multidisc clutches. Minimum Brinell Hardness 200 for heavy duty. The surface finish should be 0.9–1.5 μm CLA. Web2 days ago · Cast irons and cast steels encompass a large family of ferrous alloys, which, as the name implies, are cast to shape rather than being formed by working in the solid state. In general, cast irons contain more than 2 percent carbon and from 1 to 3 percent silicon. ... Hardness. Engineering Grades of Low Alloy Steel Castings: 70 (483) 80 (552) 45 ...

http://www.iron-foundry.com/cast-iron-hardness-range.html WebMost cast irons have a chemical composition of 2.5–4.0% carbon, 1–3% silicon, and the remainder iron. ... Rather, they increase the bulk hardness of the cast iron simply by virtue of their own very high hardness and their substantial volume fraction, such that the bulk hardness can be approximated by a rule of mixtures. songs about injustice in america

WebJan 1, 2014 · Pearlite/ferrite cast irons with variations in carbon equivalent from 3.9% to 4.3% were tested in as-cast condition and after 25 days of natural aging. In as-cast or in unaged condition, the cutting forces increased with increasing hardness in irons having less carbon equivalent, which is typical and expected. WebReasonable Cast Iron Hardness Range. The hardness has large affect to the properties of cast iron. Too low hardness will cause the low tensile strength, reduce the resistance to abrasion, so reduce the lifetime of iron castings.Too high hardness will cause the difficulty to machining, so enlarge the machining time, reduce the life time of cutters, and even can … WebMar 19, 2016 · Low C white cast irons (2.50 % C) have a hardness of about 375 HB (Brinnel hardness), while white cast irons with fairly high total C (more than 3.50 %) have a hardness as high as 600 HB. In unalloyed white cast irons, high total C is essential for high hardness and maximum wear resistance. songs about inner voice
