AISI 8620 Alloy Structural Steel Round Bar Sheet Plate, DIN 1.6523, JIS SNCM220 Introduce

AISI 8620 Steel Round Bar Sheet Plate, DIN 1.6523, JIS SNCM220

8620 steel has high hardenability without temper brittleness. It is also called DIN 1.6523 and JIS SNCM220 steel. It also has good weldability, little tendency to form cold cracks, and good machinability and cold strain plasticity. It is used to make gears, shafting, bolting, springs, hand tools and etc. 8620 steel round bar sheet plate properties and 8620 steel composition as below.

8620 Steel Application

AISI 8620 alloy steel is mainly used as a material for impact and wear resistant parts such as automobile bearings, camshafts, etc. In the carburized state it is used for gears, ring gears, shafts and crankshafts.It can also be used for the claws and cone bodies of the roller cone bits for oil drilling and metallurgical open-pit mines, and to manufacture the forgings of the connecting rod valve section of the steam turbine gear whole rotor internal combustion engine.

1.6523 Steel Characteristics

1.It is a low alloy nickel, chromium, molybdenum case hardening steel.

2.It has good external and internal strength, so there with high wear-resistant.

3.It is usually used to make many medium-strength tools.

8620 Steel Round Bar Sheet Plate Heat Treatment and Produced

Annealing

It may be given a full anneal by heat to 820℃ – 850℃, and hold until temperature is uniform throughout the section and cool in the furnace or air cooled.

Tempering

Tempering of heat treated and water quenched parts of it (not carburized) is done at 400 F to 1300 F to improve case toughness with minimal effect on its hardness. This will also reduce the possibility of grinding cracks.

Hardening

It will be austenitized at around 840°C – 870°C, and oil or water quenched depending upon section size and intricacy. And cool it in Air or oil required.

Normalizing

1675ºF (910ºC) and air cool. This is another method of improving machinability in 8620 steel material; normalizing might also be used prior to the case hardening.

Heat Treatment

This alloy may be hardened by heating to 1500 F followed by a water quench. Carburize at 1650 to 1700 F in an appropriate carburizing medium and oil quench to harden. Improved carburized case and core properties can be obtained by furnace cooling from carburizing at 1650 – 1700 F and then reheating to 1575 F.
