What is 4140 steel

4140 steel is a cold drawn annealed steel of relatively high hardenability with its chromium content providing good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength.

4140 alloy steel well to heat-treatment and is relatively easy to machine in the annealed condition. 4140 steel has good strength and wears resistance, excellent toughness, coupled with good ductility, and the ability to resist stress at elevated temperatures.

One of our customers Daniel from the UK sent us an inquiry for 4140 plate. After giving him a quote, he gave us feedback that our price is more expensive than others. We sent him the MTC to prove it was the real 4140. And suggested he compare whether the MTC of low-priced is the real 4140 or not. (4140 steel flat bar sizes)

Steel News

At present, the raw material inventory of Tangshan steel enterprises is low, the surrounding area of automobile transportation is limited, train transportation is not affected for the time being, and the collection port is limited. The delay in applying for a pass for steel companies will inevitably affect the later stage of production due to restrictions on transportation. It is understood that at present, a small number of steel companies can maintain raw material inventory for about 7 days. Some medium and heavy plate steel companies say that coke is seriously insufficient and can only maintain production operations for 2-3 days. If no raw materials enter the factory in the later stage, it is bound to be forced to stop production.
