Case Hardening Steels or Cementation Steels, in addition to the carbon element, other alloying elements such as:

They contain manganese, silicon, chromium, molybdenum and nickel and are produced by heat treatment of carbonation.

Steel 1.51919 – Steel 1.7131

In 1.7131 Samante alloy steel, due to the low percentage of carbon, we do not achieve a high degree of hardness after the hardening operation.

If the steel surface of 1.7131 becomes high carbon with carbonization operation, the surface hardness of the steel will increase. The maximum percentage of carbon C in cemented steels is 0.3%.

Steel 1.519 – Steel 1.7131 – Samantha Steel

The maximum carbon penetration in cemented steels is 2 mm below the surface. Cement steels have a hard surface, soft core and toughness and high abrasion resistance.

The steels of the cementation group also have high impact resistance.

Cement alloy steel (cementation) Hardened surface steels – Cement steel 1.51919 – Steel 1.7131

Samante alloy steels are named with different standards:

Cement 1.7131 is used to manufacture small gears, flywheels, steering components, pin shafts and pins.

Steel 7131 contains 0.17% carbon C, 0.3% silicon Si, 1.2 Mn Mn and about 1% Cr cream.

Steel 5919 – Steel 1.7131 (cementation)

Samantha 1.51919 alloy steel has an acceptable resistance to pressure and friction due to its high Cr and Ni Ni cream.

Samante 5919 alloy steel is used for making all kinds of piston gears, thousand barb – rod, pin, shaft, pin, and و, and it is also used in the plastics and melamine industries with excellent polish.

7147 cementation steel is also used to make all the parts that must have a very hard and durable surface and at the same time a soft and deformable core.

Samante 7147 steel is used to make different types of gears – steering shaft – cranville and python and..
