Quality Assurance Astm 5140 Chemical Composition Analysis - China

ASTM 5140 chemical composition is as follows:

- Carbon (C): 0.38%-0.43%

- Silicon (Si): 0.15%-0.35%

- Manganese (Mn): 0.70%-1.00%

- Chromium (Cr): 0.70%-1.00%

- Sulfur (S): ≤0.035%

- Phosphorus (P): ≤0.035% 5140 steel is an alloy structural steel, the main alloying elements include chromium and manganese.

The addition of these elements can improve the strength, hardness and wear resistance of 5140 steel.

Specifically:

- The carbon content is 0.38%-0.43%, which provides 5140 steel with good strength and hardness.

- Silicon can improve the oxidation resistance and mechanical properties of steel.

- Manganese can improve the strength, hardness and toughness of steel.

- The addition of chromium further improves the wear resistance and corrosion resistance.

- The sulfur and phosphorus content is low to avoid the brittleness of the steel.

5140 steel is commonly used to manufacture various mechanical parts, such as gears, bearings, connecting rods, etc., and is widely used in the automotive, machinery and other industries.

After proper heat treatment, 5140 steel can obtain better mechanical properties.
