What is ASTM A48?
This specification covers gray iron castings intended for general engineering use where tensile strength is a major consideration. Casting are classified on the basis of the tensile strength of the iron in separately cast test bars.
What is ASTM 35?
Converted from Brinell hardness….
| ASTM class 35 Standard gray iron test bars, as cast | |
|---|---|
| Categories: | Metal; Ferrous Metal; Cast Iron; Gray Cast Iron |
| Material Notes: | 1293 kg transverse load on test bar. |
Is 210 GREY cast iron?
The Pig Iron and Cast Iron Sectional Committee decided to revise IS 210 by merging it with IS 6331 : 1987. The higher grades of grey cast iron (that is, Grades FG 300, FG 350 and FG 400) present special difficulties for section 10 mm and thinner.
What is FG iron?
Standard Flake Iron (FG)
What are the properties of GREY cast iron?
Gray cast iron characterized by flake graphite has certain strength, hardness, modulus of elasticity, shock absorption, wear resistance and thermal conductivity, especially with excellent casting performance, good cutting performance and low casting cost. So far, it is still the most widely used cast iron in the world.
Is 210 a material property?
IS 210 Grade FG200
| Unit | Property Name | Value |
|---|---|---|
| GPa | Elastic modulus | 92.4 |
| MPa | Tensile strength | 207 |
| g/cm³ | Density | 7.15 |
| [-] | Hardness, Brinell | 187 |
Which cast iron is poor under tension and why?
Gray cast irons are comparatively weak and brittle in tension due to its microstructure; the graphite flakes have tips which serve as points of stress concentration.
Is cast iron self lubricating?
Cast iron is assessed as a self-lubricating metal-base composite material. It was found that the friction and wear behaviour of cast iron are influenced by the formation of a graphite surface layer.
Is cast iron ferrous or nonferrous?
Ferrous metals
| Ferrous metal | Properties |
|---|---|
| Cast iron | Brittle if thin, can be cast in a mould, strong compression strength, good electrical and thermal conductivity but poor resistance to corrosion |
| High-carbon steel (tool steel) | Hard but brittle, less malleable than mild steel, good electrical and thermal conductivity |
Is cast iron good for health?
So, Is Cooking in Cast Iron Healthier than Cooking in Other Pans? In short: No. You’d have to be mouse-sized to see quantifiable health benefits from mineral intake exclusively with cast iron. Because mineral transfer happens at such a small scale, it’s safe to say that cast iron is not any healthier than other pans.
