Lower Price Low Carbon Alloy Steel 4340 Steel Hardness
4140 and 4340 alloy steel - Metal and Metallurgy
The 4340 alloy steel by virtue of having nickel as an alloying element increases hardenability and increases toughness over 4140. Impact energy relates to toughness but when it comes to fracture toughness data, 4340 will have higher toughness over 4140 at similar strength levels (quench and temper).

Carbon steel - Wikipedia
Carbon steel is broken down into four classes based on carbon content: Low-carbon steel Edit. 0.05 to 0.30% carbon content.. Medium-carbon steel Edit. Approximately 0.3–0.8% carbon content. Balances ductility and strength and has good wear resistance; used for large parts, forging and automotive components.
Hard turning: AISI 4340 high strength low alloy steel and
AISI 4340 high strength low alloy steel Fig. 1 shows the effect of cutting speed on the turning forces when cutting AISI 4340 steel hardened to 42 and 50 HRC using a feed rate f = 0.2 mm/rev and a depth of cut a p = 1 mm. Average cutting force ( F c ), feed force ( F f ) and thrust force ( F p ) are presented.
How many percentages of carbon content make steel with the
This depends on which alloy family you choose.. Music wire (ASTM A228) can be drawn to 450,000+ psi tensile strength Music Wire | Mount Joy Wire and is a simple high carbon steel with up to 1.00% carbon Springs & Things Inc. The strength is due to the cold work of drawing down in diameter.

Through-Hardening Low Alloy Steel Bar 4340 - Atlas Steels
Atlas 4340 is a nominally 1.8 percent Nickel Chromium Molybdenum low alloy steel of high hardenability, with high strength and toughness in relatively large sections achieved with a "quench-and-temper" heat treatment.
Metallurgy Matters: Carbon content, steel classifications
Steel classification is important in understanding what types are used in certain applications and which are used for others. For example, most commercial steels are classified into one of three groups: plain carbon, low-alloy, and high-alloy. Steel classification systems are set up and updated
Knife Steel & Handle Material Chart - MidwayUSA
A medium carbon, low alloy steel that hardens well. This steel is ideally suited to blades with a very thick cross-section such as tomahawks and axes. Extremely tough and impact resistant, this steel is most often used on blades which are hafted and/or thrown.
4340 Alloy Steel Round Rod, Annealed/Rough Turned, 0
Steel is an iron alloy with carbon and other elements that modify the steel to achieve specific properties. In general, steels with higher carbon content have greater strength, hardness, and wear resistance, while those with lower carbon content have more formability, weldability, and toughness.
Carbon Steel vs Stainless Steel | Metal Casting Blog
Carbon steel and stainless steel have the same basic ingredients of iron and carbon. Their main difference is alloy content—carbon steel has under 10.5 percent alloy content, while stainless steel must contain 10.5 percent chromium or more.
