4340 steel description-its toughness and strength in relatively large sections | OTAI

What is 4340 steel

4340 alloy steel is a high-quality Quenched and Tempered Alloy Structural steel, It belongs to the high-quality medium carbon, Oil Quenched & Tempered Hardness is 28-34 HRc.4340 Annealing delivery hardness less than 250HB.

4340 steel properties are very similar to GB 40CrNiMo steel, JIS SNCM439, and DIN 1.6511 36CrNiMo4 Alloy structural steel. In most work environments, 4340 is equivalent to 40CrNiMo, 1.6511 36CrNiMo4, and SNCM439 steel.

Why Choose OTAI

1)All year round, Otai can guarantee 4340 bars’ stock in different thicknesses and lengths, which can be customized.

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

3)Otai is a leading China supplier of 4340 steel, working with Bohler, Uddeholm, Thyssenkrupp, with ISO9001 certified.

Customer’s story

We would like to share a real case of our customer with you. Stacy from Indonesia send us an inquiry about the 4340 steel alloy, which required a lot of specifications and a small quantity. Stacy 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 Stacy placed the order successfully. After receiving the goods, she said that he would seek our cooperation for a long time. (4340 steel description)

Steel News

At present, nine counties and cities in Tangshan have lifted the management of regional blockade control.
The clustered epidemics in many places in China have dragged down the production and operation of the manufacturing and construction industries. In the short term, the demand for steel has been unstable, and the rise in steel prices is insufficient.
Once the social “dynamic clearing” is realized in various places, the demand for steel will be released retaliatory, the demand growth may be higher than the supply, the inventory will enter a stage of decline, and there may still be room for steel prices to rise.

Recently, the epidemic situation across the country has shown a trend of high local concentration and multi-point distribution, which has affected the supply side, demand side, logistics, and warehousing of the domestic bulk commodity market to varying degrees.
As of April 8, according to incomplete statistics from Mysteel, a total of 21 provinces have released the latest information on the resumption of work. Among them, 19 counties (cities, districts) and development zones (management zones) in Tangshan have been lifted in an orderly manner. Vehicle transportation in the Handan area is hindered, and it is difficult for foreign resources to enter the Handan market, resulting in poor arrival of goods at the base. Xuzhou has strict traffic control, and the circulation of scrap steel resources is seriously hindered; Gulou District and Quanshan District are the most controlled areas, and scrap steel sites are basically closed.
