What type of material is 8620?
What type of material is 8620?
8620 is a low carbon nickel chromium molybdenum alloy steel with good carburized properties. The nickel content contributes to a high strength case toughness and above average core toughness. The chromium and molybdenum support the proper formation of carbides resulting in good surface hardness and wear.
Is 8620 a low alloy 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. This case-hardening will result in good wear characteristics.
CAN 8620 steel be welded?
Average cutting speed 127 ft/min. 8620 can be forged at 2200 down to 1800 F prior to hardening or carburizing. 8620 is excellent for welding applications.
How hard can you get 8620 steel?
8620 can be hardened to 1500° F followed by water quench. Carburize at 1650° – 1700° F in an appropriate carburizing medium and oil quench to harden. Tempering of carburized parts is done at 250° – 300° F and will result in the alloy having a core strength of approximately 135,000 psi minimum.
How do I choose steel grade?
Carbon provides steel strength, hardness and wear-resistance, so you want to select a grade of steel with just enough carbon to meet the desired property levels. Grades that have lower carbon percentages are softer and easier to machine and form and have the ability to be welded.
What is 8620H steel?
8620H Hot Rolled SBQ Bar Grade 8620H is a case hardening steel that retains strength, even at elevated temperatures. The “H” indicates the material meets hardenability according to ASTM A304. Eaton Steel Bar Company stocks many diameters of 8620H hot rolled steel bar available to meet the market demand.
What can you do with AISI 8620 steel?
Pre hardened and tempered (uncarburized) 8620 can be further surface hardened by nitriding but will not respond satisfactorily to flame or induction hardening due to its low carbon content. Steel 8620 is suited for applications which require a combination of toughness and wear resistance. This grade is commonly supplied in round bar. 1.
What are the grades of 8620 round bars?
Equivalent Grades of 8620 round bars : Standard AISI / SAE 8620 ASTM A29 8620 WERKSTOFF NR. 21NiCrMo22, 21NiCrMo2 BS 970 805A20, 805M20 UNI 20NiCrMo2

Which is better AISI 8620 or SAE 8617?
SAE steel 8620 offers high external strength and good internal strength, making it highly wear resistant. AISI 8620 steel has a higher core strength than grades 8615 and 8617. SAE 8620 alloy steel is flexible during hardening treatments, thus enabling improvement of case/core properties.
