4140 steel plate has high fatigue strength, excellent toughness, and good corrosion resistance. One disadvantage is the extra care that must be taken when welding it.
This material is often used for shafts, crankshafts, gears, collars, and machinery parts because of its toughness, abrasion and impact resistance, and high fatigue strength.
It is hardened by heating to 1550°F or 845°C followed by quenching in oil.
