Truck spring are usually 5160 , which is a decent steel for heavy duty blades. it has the great advantage that heat treat temps are far less critical than for high tech steels. Get it little above non-magnetic, hold it at that heat for ten minutes if can, quench in warm oil. Horse-drench oil works well if you can get it. (veterinarian or vet supply) Transmission fluid is also good. Temper at around 400 for an hour. CAR springs are less trustworthy- sometimes they are poorer steel. Now there ARE knifemakers' supply co's that will well you two feet of steel at a modest price. 5160 is widely available. 8670 , L6 or 15N20 -steels with 1 to 2% nickel- are also good. Very tough. L6 tends to be spendy.
