Product Description

SAE8620/1.6523 Special Mould Steel Bar For Structure Tool Steel

20CrNiMo AISI, former U.S. Department of steel in SAE 8620 steel. Hardenability is similar to that of 20CrNi steel. Although the Ni content in the steel is half 20CrNi steel, but due to the addition of a small amount of Mo element, the upper part of Austenite Isothermal Transformation Curve to the right; and because the appropriate increase of Mn content in the steel hardenability is still good, high strength than 20CrNi steel.

2. Features:
1) High temperature resistance.
2) Good machinability and cold strain plasticity.
3) It is used in quenching and tempering or carburizing and quenching.
4) Higher hardenability, no temper brittleness, weldability is very good,small forming cold crack tendency.

3. Application:
1) Often used in the manufacture of gears in engines and transmission systems of small and medium automobiles and tractors
2) It can substitute for the 12CrNi3 steel to produce the carburized parts and cyaniding parts with higher core performance, such as the claw and cone of the roller bit for oil drilling and metallurgy.
3) Gears used for manufacturing steam turbines, rotors, internal combustion engines, connecting rods, valve sections, forgings, etc..
