4140 plate ASTM – -High quality 4140 Alloy Steel Plates Black Peeled Polishing | OTAI
What is 4140 steel
4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components. For example, axles, shafts, bolts, gears, and other applications.
Similar to alloy grade AISI 4130 chrome moly alloy steel but with slightly higher carbon content.
The higher carbon content of 4140 steel gives greater strength and heat treatment capabilities in comparison to AISI / ASTM 4130 alloy steel.
However, it does have inferior weldability characteristics.
Steel news
Due to the closure and control, there may be temporary cancellation of flights, and the export of goods from other cities may be arranged in the next few days. Those who have booked Shanghai flight positions need to pay more attention to Shanghai flights and ports.
The direct impact of the domestic epidemic is to reduce transportation capacity, which leads to the continued increase in logistics prices.
The outbreak of current round of the epidemic is expected to drive up global shipping charter costs and prolong the transit time of goods. Finally, remind shippers and forwarders who have shipping plans to make stocking plans in advance!

Customer’s story
We would like to share a real case of our customer with you. Jay from Brazil send us an inquiry about the 4140 sheets, which required a lot of specifications and a small quantity. James asked many suppliers who were unwilling to cooperate and finally found us. We are the source manufacturer so that we can meet the needs of customers to customize the specifications of goods. Then James placed the order successfully. After receiving the goods, he said that he would seek our cooperation for a long time. (4140 plate ASTM)
FAQ
What is 4140 steel used for?
It can be used for manufacturing forgings with higher strength and larger tempering cross-section than 35CrMo steel, such as big gear for locomotive traction, supercharger drive gear, rear axle, connecting rod, and spring clamp with great load and etc.
What is the hardness of 4140?
It is offered in the cold finished annealed condition. Typical hardness is Rockwell “C” 19/24. Typical tensile strength 114,000 PSI. Its wear-resistant properties far exceed that of “cold roll” steels.
What is 4140 QT?
As a quality alloy steel grade 4140 is commonly supplied quenched and tempered (QT) which offers good high tensile properties. It is characterized by its good ductility and shock-resistant properties that combine with good wear resistance.
Is 4140 good for forging?
4140 has high strength, hardenability, good toughness, small deformation during quenching, high creep strength, and long-lasting strength at temperature.
Is 4140 steel stainless steel?
NO. it’s alloy steel.
