Comparison Of Alloy Steel And High Carbon Steel

• poor hardenability of high-carbon steel

Carbon steel selection of water quenching, its critical quenching into the diameter of 15 ~ 20mm, for parts with a diameter greater than 20mm, even if the water quenching may not be quenched, can not ensure that the entire section to get the same comprehensive mechanical properties. Therefore, for large parts with high requirements, carbon steel is certainly not applicable. And alloy steel has high hardenability, can be used to manufacture large cross-section, complex shape parts.

• the high temperature strength of high carbon steel is low, poor red hardness

Carbon steel is used at temperatures above 200 ℃, its strength and hardness will be quickly reduced. And alloy steel tempering stability. Red hardness is good, can work at higher temperatures.

• high carbon steel can not get good overall performance

For example, the use of tempering treatment to try to obtain a good overall performance, if you want to ensure high strength, the toughness is low, if you want to ensure good toughness, the strength is low. This is due to the poor tempering stability of carbon steels. Therefore, carbon steel to get the overall performance is far worse than alloy steel, that is, alloy steel has a good degree of toughness.

• high carbon steel does not have special properties

For example, the requirements of high-temperature hardness or tension, oxidation, corrosion resistance, special electrical, magnetic properties, etc., with carbon steel can not be obtained, only the use of alloy steel to meet the above requirements. Carbon steel also has some advantages, such as by changing its carbon content and appropriate heat treatment, you can get many industrial production requirements of the performance. Due to the low price of carbon steel, easy to produce, good processing performance, is still the most widely used steel materials in industry, accounting for more than 80 per cent of the total amount of steel.
