What is 8620 alloy steel?
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.
How strong is 8620 alloy steel?
700-1100 MPa
AISI 8620 has good wear resistant with case hardness HRC 60-63 when carburized, hardened and tempered. Compared with grades 8615 and 8617, it shows good core strength and toughness properties with a typical tensile strength range of 700-1100 MPa,in small to medium sized sections.
What is the hardness of 8620 steel?
8620 Steel Mechanical Properties
| Properties | Metric | Imperial |
|---|---|---|
| Poisson’s ratio | 0.27-0.30 | 0.27-0.30 |
| Izod Impact | 115 J | 84.8 ft.lb |
| Hardness, Brinell | 149 | 149 |
| Hardness, Knoop (converted from Brinell hardness) | 169 | 169 |
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.
How hard is 4150 steel?
Hot rolled 4150 steel bar is a medium/high-carbon alloy steel that contains chromium and molybdenum. Hot rolled 4150 steel is known for its increased hardenability and mechanical properties….Estimated Mechanical Property Ranges for “Grade 4150”
| Tensile strength (psi) | 100,000 – 110,000 |
|---|---|
| Brinell Hardness (BHN) | 210 – 240 |
CAN 8620 steel be welded?
MACHINEABILITY AND WELDABILITY 8620 can be forged at 2200 down to 1800 F prior to hardening or carburizing. 8620 is excellent for welding applications.
Can 8620 be flame hardened?
Carbon and alloy steels with a carbon content in the range 0.40 – 0.45% are most suitable for this process. In some cases, parts made from alloy steels such as 4320, 8620 or 9310, like steel and paper mill rolls, are first carburized to a required case depth and slow cooled, and then induction hardened.
What is ASTM A572?
The ASTM A572 specification is the Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel for plates used in general construction and structural applications. ASTM A572 grades are used in a wide variety of structural applications in many market segments.
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 is 80 alloy steel?
Grade 80 chain is rugged, versatile, high-strength, low-weight chain manufactured from special analysis alloy steel designed for overhead lifting. It is quenched and tempered before proof testing and the ultimate tensile strength is over twice that of ordinary steel chain.
