What is 1055 carbon steel?

Answer 1

1055 = 55% carbon , 1050 = 50% carbon. last two digits are the percentage of carbon in the alloy steel

which steel is better for tool making

Just as a small note its 0.55% carbon and 0.50% carbon it takes very little carbon to change the various properties of a given steel.

Answer 2

1055 is a Standard grade Carbon Steel. It is composed of (in weight percentage) 0.50-0.60% Carbon (C), 0.60-0.90% Manganese (Mn), 0.04%(max) Phosphorus (P), 0.05%(max) Sulfur (S), and the base metal Iron (Fe). Other designations of AISI 1055 carbon steel include UNS G10550 and AISI 1055.

1050 is a Standard grade Carbon Steel. It is composed of (in weight percentage) 0.48-0.55% Carbon (C), 0.60-0.90% Manganese (Mn), 0.04%(max) Phosphorus (P), 0.05%(max) Sulfur (S), and the base metal Iron (Fe). Other designations of AISI 1050 carbon steel include UNS G10500 and AISI 1050.

So the last digits shows the percentage of Carbon; and when you increase the amount of carbon you increase hardness and strength.

So, 1055 is stronger than 1050.

Answer 3

1055 carbon steel is usually found in heavy duty tools and firearms. It is comprised of .55% carbon. The higher the carbon content, the stronger the steel.

Answer 4

The 55 and 65 in these numbers designates carbon content of the steel. 1065 carbon steel will be stronger and harder than 1055, but also more prone to shattering if it with enough force.

Answer 5

The carbon content of SAE 1055 Steel is .55% and the carbon content of SAE 1095 Steel is .95%.
