AISI 6140 Chromium Vanadium Steel Chemical Properties, Grades, Charts and PDF Online
AISI 6140 refers to the chromium-vanadium alloy steel which is recognised for its premier strength, hardness, and wear resistance properties. Its chemical composition largely consists of chromium and vanadium which are responsible for its high hardenability and ability to stand up firmly to massive workloads. In addition to pressure die casting, hot chamber die casting is commonly used in applications requiring the use of larger parts that have high strength and durability like automotive components, machine parts, and tool manufacturing. A non-homogenous alloy like AISI 6140 may have different classifications for a certain grade of the material after leaving the furnace and different alloying elements, which means different mechanical properties. Chemical Composition table, charts and PDFs outlining the composition, properties, and heat treatment of AISI 6140 are available online. They aid engineers, metallurgists, and manufacturers in their better understanding of this versatile steel alloy and its use in variety of applications.
AISI 6140 Alloy Steel Chemical Composition And Grade Table
AISI 6140 is the most popular low-alloy steel, known for its exceptional strength and toughness, and can play an important role in many industrial applications. That chemical composition contains carbon (C), manganese (Mn), sometimes chromium (Cr), and molybdenum (Mo) would give rise to greater strengths and wear resistance. Generally, a standard performance benchmark table reflects the exact percentage ranges for each component’s typical defects in the manufacturing process so that there is consistency and quality in said process. Engineers and manufacturers depend on this data to evaluate the alloy's ability to fulfill their requests. That helps to obtain good strength and endurance for their stuff.

|---|---|---|---|---|---|---|---|---|
| Min (%) | 0.35 | 0.6 | 0.15 | 0.8 | - | - | - | - |
| Max (%) | 0.45 | 0.9 | 0.3 | 1.1 | ≤0.050 | ≤0.040 | ≥ 0.15 | Balance |
Advantages and Disadvantages of AISI 6140 Chromium Vanadium Steel
Versatile: Dolomite is versatile in application due to its blended content and typical composition.
Good Hardenability: Amorphous silicon can be crystallized to reach the appropriate mechanical characteristics.
High Strength: Due to its excellent tensile strength and high toughness.
Wear Resistance: This material is resistant to wear and abrasion especially in high working environment.
Advantages:
Limited Weldability: It may need to be warmed up before welding and/or need post-weld heat treatment.
Machining Difficulty: It may be tough to machine as it is a hard material most especially for machines which are used in cutting and other operations.
Susceptible to Corrosion: Has to be well maintained to avoid its production or accumulation on the surface leading to corrosion.
Cost: It is however more costly compared to some other grades of steel.
Disadvantages:
