AISI 4340 (E4340) alloy steel is a medium carbon, low alloy steel known for providing a good balance between strength and malleability. Alloy 4340 is composed of (descending in order by weight)iron, nickel, chromium, manganese, carbon, molybdenum, silicon, phosphorus and sulfur. With proper working and strengthening, items made from 4340 have excellent wear and durability qualities.

It is alloy steel with low carbon and high nickel. About the coating and softening for leather knife sheath, it is a great choice. 4340 alloy steel bar is used widely in the aerospace industry because of
tensile yield strength of steel chart Tensile / yield strengths and ductilities for some of the plain carbon and low alloy steels are given in the following mechanical properties of steel chart. Yield Strength, Tensile Strength and Ductility Values for Steels at Room Temperature
Higher carbon steels. Manganese is often added to improve the hardenability of low carbon steels. These additions turn the material into a low alloy steel by some definitions, but AISI 's definition of carbon steel allows up to 1.65% manganese by weight.
Use 4340 alloy steel for power transmission and structural applications that involve extreme impact, heat, and wear.
AISI 4340 steel is a medium carbon, low alloy steel known for its toughness andstrength in relatively large sections. AISI 4340 is also one kind ofnickel chromium molybdenum steels. 4340 alloy steel is generallysupplied hardened and tempered in the tensile range of 930 – 1080 Mpa.Pre hardened and tempered 4340 steels can be further surface hardened by flame or induction hardening and by nitriding.
4130 alloy steel has a low carbon content that provides good weldability. It's often used for gears, fasteners, and structural applications. High Strength 4340 Alloy Steel
4340 is a 1.8% nickel chromium molybdenum high hardenability high tensile steel generally supplied hardened and tempered in the tensile range of 930 1080 Mpa (condition U) (Rc 28 36).. Characterised by high strength and toughness in relatively large sections.
Alloy Steel Alloy steel is a type of steel that has presence of certain other elements apart from iron and carbon. Commonly added elements in alloy steel are manganese, silicon, boron, chromium, vanadium and nickel. The quantity of these metals

ASTM A29 specification is standard specification for Steel Bars, Carbon and Alloy, Hot Wrought, General Requirements. There are following kind of carbon and alloy steel bars under this standardhot rolled carbon steel bar, cold finished carbon steel bars, hot rolled alloy steel bars, cold finished alloy steel
In Europe, shock steels often contain 0.5 0.6 % carbon and around 3% nickel. 1.75% to 2.75% nickel is still used in some shock resisting and high strength low alloy steels (HSLA), such as , 4340, and Swedish saw steel, but it is relatively expensive. An example of its use is in the production of jackhammer bits.
The four main classes of carbon steels are mild and low carbon steel, medium carbon steel, high carbon steel, and ultra high carbon steel. Mild and low carbon steels contain 0.16–0.29% carbon. They are the most common form of steel as they come at a relatively low cost and provide material properties that are acceptable for many applications.
