42crmo4 Steel sheet – – DIN 42CrMo4 1.7225 Alloy Steel Plate & Sheet | OTAI

What is 42crmo4 steel

42crmo4 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.

42crmo4 alloy steel well to heat-treatment and is relatively easy to machine in the annealed condition. 42crmo4 steel has good strength and wear resistance, excellent toughness, coupled with good ductility, and the ability to resist stress at elevated temperatures. (42crmo4 flats steel)

One of our customers Daniel from UK sent us an inquiry for 42crmo4 Steel sheet. 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 42crmo4. And suggested he compare whether the MTC of low-priced is the real 42crmo4 or not. (42crmo4 Steel Bar Supplier)

What is 42CrMo4 steel

42CrMo4 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 42CrMo4 steel gives greater strength and heat treatment capabilities in comparison to AISI / ASTM 4130 alloy steel.

However, it does have inferior weldability characteristics.

Why Choose OTAI

1)All year round, Otai can guarantee our 42CrMo4 alloy plates stocks are more than 1500 tons. Different thicknesses and lengths can be customized.

2)After placing an order, shipment can be arranged immediately.

3)Otai is a leading China supplier of 42CrMo4 steel, working with Uddeholm, Thyssenkrupp, with ISO9001 certified.

Customer’s story

We would like to share a real case of our customer with you. James from Canada send us an inquiry about the 42CrMo4 steel bar, 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. (42CrMo4 steel supplier)
