Is 8620 high 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….Thermal Conductivity.

Can you weld case hardened steel?
By using suitablepost-welding heat ways and picking weld joints that equitably circulate weight on the metal, one can effectively weld hardened steel. One can preheat it or use a low hydrogen bar whenwelding. However, you have to preheat it and, at that pointre-temper in the wake of welding, If it’s devicesteel.
Can I weld steel with a TIG welder?
TIG welders can be used to weld steel, stainless steel, chromoly, aluminum, nickel alloys, magnesium, copper, brass, bronze, and even gold. TIG is a useful welding process for welding wagons, bike frames, lawn mowers, door handles, fenders, and more.
Can you weld cutting edge?
Most weld-on cutting edge is 1060 carbon steel, a preheat would be best but plenty is welded without. It can be tricky to keep the edge flat, I usually tack the edge well as tacks will pull out of the hard edge easily, then clamp it flat and begin welding.
What is 8620 alloy steel?
AISI 8620 alloy steel is a common, carburizing alloy steel. This alloy steel is flexible during hardening treatments, thus enabling improvement of case/core properties.
What is an AISI 8620 used for?
Applications. The AISI 8620 can be used for a number of medium-strength applications such as camshafts, fasteners, gears, and chains/chain pins.
How to heat treat 8620 tool steel?
Heat Treatment of AISI 8620 Steel 1 This alloy may be hardened by heating to 1500 F followed by a water quench. Carburize at 1650 to 1700 F in an… 2 Tempering Of 8620 Tool Steel 3 And the carburized parts is done at 250 to 300 F and this will result in the alloy having a core strength of… More
What is the welding method for 8620?
Forming characteristics of 8620 alloy are good in the annealed condition. The alloy may be welded by conventional methods, usually gas or arc welding. Preheating at 400 F is beneficial and subsequent heating after welding is recommended – consult the approved weld procedure for the method used.
