All About Steel 52100 (properties, strength and uses)

This article will analyze a high-carbon, low-alloy steel known as 52100 steel, to show where it best fits as an engineering material. First, we will look at the physical properties of 52100 steel, and then we will investigate its working characteristics, as well as the possible uses of this versatile metal.

Physical properties of 52100 steel

52100 steel appears to have a different nomenclature structure than other three- or four-digit steels, but this is solely due to specific differences between the SAE and AISI nomenclature indexes. The first digit (5) indicates that this steel is mainly alloyed with chromium, and the second digit (2) represents an alloy percentage greater than 1%. In other words, the second digit does not specify the exact percentage of chromium, but only that it is alloyed in a higher percentage than other similar steels. The last three digits indicate the average percentage of carbon used in the steel; Thus, in the case of 52100 steel, an average of 1.00% carbon is used in its mixture. Below is a list of the exact chemical composition of 52100 steel, with its tolerances:

Elements that make up 52100 steel

0,98- 1,1% Carbon

1,3-1,6% Chromium

0,25-0,45% Manganese

<= 0,025% Fósforo

0,15-0,3% Silicon

<= 0,025% Azufre

52100 steel is a high-carbon chromium alloy steel that has a density of 7.81 g/cm3 (0.282 lb/in3). It can be hardened by hot and cold working processes and responds to annealing and tempering and can be strengthened by heat treatment process. It can be easily forged and formed, as well as machined, from its annealed state. Although not generally used for welding, 52100 steel is especially useful in bearings, mill rolls, and vehicle parts thanks to its combination of strength, hardness, and workability. The most common form of 52100 steel is bar, but it can also be found in tube, wire, flat rolled, and forged.

Applications of 52100 steel

As already mentioned, 52100 steel is primarily used in bearing steel, as well as in bearing manufacturing equipment. Its toughness and hardness make it suitable for use in blades and cutlery, although it is more difficult to heat treat than other more common blade steels. Below is a list of other common applications for 52100 steel:

Antifriction bearings

mill rollers

Punches, taps and dies

Automobile and aircraft parts

Fixing elements

and more.
