AISI 8620 / DIN 1.6523 Steel Round Bar and Sheet On Stock

AISI 8620 / DIN 1.6523 Steel Round Bar and Sheet On Stock

Description

AISI 8620 steel is alloy steel. It was called 20CrNiMo in China. Its max hardness is HB225. The processing of carbonization and heat treatment, its surface hardness and wear resistance will be better. The hardness is 60-63HB. Due to the low-carbon and medium alloy element, its property has toughness after hardening.

8620 Steel Chemical Composition:

• Carbon: 0.18%-0.23%
• Silicon: 0.15%-0.35%
• Manganese: 0.70%-0.90%
• Sulfur: ≤0.035%
• Phosphorus: ≤0.035%
• Chromium: 0.40%-0.60%
• Nickel: 0.40%-0.70%
• Copper: ≤0.030%
• Molybdenum: 0.15%-0.25%

8620 Steel Properties:

• Intensity Strength: ≥100MPa
• Yield Strength: ≥785MPa
• Hardness: ≤197HB

8620 Steel Application:

It is used in the manufacture of gears in engines and transmission systems for small and medium-sized cars and tractors. And because of the properties of the core is great, so it can be used in the fields for oil drilling and metallurgy.
