4140 ht plate — 4140 Quenched & Tempered Steel Plate | OTAI
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 UK sent us an inquiry for 4140 ht 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 Bar Supplier)

FAQ
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.
Is 4140 hardened steel?
Atlas 4140 is Chromium-Molybdenum through-hardening steel of medium hardenability. It is general-purpose high-tensile steel with a medium strength level and good impact properties.
What is 4140 steel's mechanical properties?
On the hardenability of steel, 4140 heat treatment has good strength and good comprehensive mechanical properties, good manufacturability, high yield. The highest temperature is 427 degrees Celsius.
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.
