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 flat bar distributors)

Steel News

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.

4140 strength, high hardenability, good toughness, quenching deformation of small, high temperature creep rupture strength, and high.

What is 4140 steel?

Steel grade 4140 is alloy steel for quenching and tempering. Grade 4140 products are mainly used for the manufacture of machine parts. Steel is made in accordance with the requirements of the DIN EN ISO 683-2 standard (formerly EN 10083-3). Classification: Heat-treated alloy steel.

What type of alloy steel is 4140?

4140 steel is a chromium, molybdenum, manganese low alloy steel plate that is known for its toughness, high fatigue strength, and high torsional strength.

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.
