What kind of material is 8620?
What kind of material is 8620?
A medium-strength, low-carbon alloy steel, 8620 contains good toughness and strength properties, along with good core strength. 8620 has a high case toughness and above average core toughness due to the nickel content. Additionally, it is the most widely used carburizing alloy steel.
What is the alloy content of 8620?
Alloy 8620 steel is a low-carbon carburizing/case-hardening steel that contains nickel, chromium, and molybdenum as alloying elements. The nickel content provides 8620 with good ductility and toughness while the chromium and molybdenum in its composition increase its hardness penetration and wear.
What is the carbon content in AISI 8620 steel?

Is 8620 steel stainless?
Both AISI 304 stainless steel and normalized SAE-AISI 8620 are iron alloys. They have 72% of their average alloy composition in common. There are 31 material properties with values for both materials.
Will 8620 steel rust?
These 400°C tempered specimens can exhibit an ultimate tensile strength of 1100 MPa and a brittle-ductile transient temperature of -40°C. Besides, the 400°C tempered SAE 8620 steel is only susceptible to local attack of pitting corrosion and can exhibit an excellent corrosion resistance.
Is 8620 a tool steel?
AISI 8620 alloy steel is a common, carburizing alloy steel. This alloy steel is flexible during hardening treatments,and thus enabling improvement of case/core properties. The following datasheet will provide more details about AISI 8620 tool steel.
How is 8620 steel made?
8620 alloy steel is composed of (in descending order of percentage) iron, carbon, silicon, molybdenum, manganese, nickel, chromium, sulphur and phosphorus. These ingredient elements must be within certain weight percentages to create the 8620 alloy. The average tensile strength of steel alloys is 758 to 1882 Mpa.

What are the main uses for 8620 carbon steel?
Principal Design Features. AISI 8620 is a hardenable chromium,molybdenum,nickel low alloy steel often used for carburizing to develop a case-hardened part.
What is material 8620?
8620 RD 8620 is a “triple alloy” carburizing material. The nickel properties imparts good toughness and ductility, and the chromium and molybdenum contribute increased hardness penetration and wear. 8620 material is readily carburized, and the well-balanced alloy content permits hardening to produce a strong, tough core and high case hardness.
What is 8620 steel?
8620 Steel is a carburizing alloy steel that can be used in a variety of medium strength applications. In addition, 8620 steel is provided in Hot Roll condition or HR. It’s a low Carbon, Ni – Cr – Mo (Nickel Chromium Molybdenum) alloy.
