The manganese content in cast iron should be kept below __________

Ferrous metals are known for their durability and tensile strength. They are often used in construction, including buildings, bridges, and trains.  Here are some examples of ferrous metals: Carbon steel Has a higher carbon content than other types of steel, making it very hard. Alloy steel Has greater strength and durability than carbon steel, and can achieve a given strength with less material weight. Gray iron Consists of graphite flakes in a metallic matrix. It's one of the most commonly used ferrous alloys because of its low cost of production and attractive properties. White... Show more

Ferrous metals are known for their durability and tensile strength. They are often used in construction, including buildings, bridges, and trains. 

Here are some examples of ferrous metals:

Carbon steel
Has a higher carbon content than other types of steel, making it very hard.

Alloy steel
Has greater strength and durability than carbon steel, and can achieve a given strength with less material weight.

Gray iron
Consists of graphite flakes in a metallic matrix. It's one of the most commonly used ferrous alloys because of its low cost of production and attractive properties.

White iron
A ferrous alloy that typically contains 11-30% chromium and 1.8-3.6% carbon. 

Other examples of ferrous metals include: Steel, Iron.
