4140 round bar is a medium-carbon alloy structural steel, It exhibits high strength, good toughness, and wear resistance. Its tensile strength can reach 850–1000 MPa, yield strength 600–800 MPa, with an elongation of approximately 20% and making it suitable for manufacturing high-load mechanical components such as gears, shafts, and moulds.
Key Characteristics
Strength and Toughness: Quenching and tempering heat treatment achieves a balance between hardness and impact resistance.

If you want to purchase 4140 steel from China, no matter 4140 hot rolled bar or hot rolled plate, you can find the stocks from China market, but stock will be not too big, because domestic always use 42CrMo. lf you can accept 42CrMo instead of 4140 material, it will save the cost.
For hot forged material, usually there are some stocks for hot forged bar, but there wil be no any stock for block orforging parts, the MOQ will be only 1pcs because it's easy to get the raw material from market.
