Here are 10 key steel grades commonly used in various applications

1. Carbon Steel (ASTM A36)

Application: Structural steel used in construction, bridges, and general structural purposes.

2. Tool Steel (A2, D2, O1)

Application: Used for cutting tools, dies, molds, and precision parts requiring high hardness and wear resistance.

3. Stainless Steel (304, 316)

Application: Widely used in food processing equipment, kitchen appliances, chemical processing equipment, and marine applications due to its corrosion resistance.

4. Alloy Steel (4140, 4340)

Application: Used in machinery parts, automotive components, and aerospace structures due to its high strength, toughness, and wear resistance.

5. Galvanized Steel (ASTM A653)

Application: Steel coated with zinc to prevent corrosion, commonly used in construction, automotive, and HVAC industries.

6. High-Speed Steel (M2, M42)

Application: Used for cutting tools such as drills, taps, and end mills due to its high hardness, heat resistance, and wear resistance at high speeds.

7. Weathering Steel (ASTM A588)

Application: Used in outdoor structures like bridges, buildings, and sculptures due to its ability to form a stable rust-like appearance, eliminating the need for painting.

8. Tool Steel (A2, D2, O1)

Application: Used for cutting tools, dies, molds, and precision parts requiring high hardness and wear resistance.

9. Spring Steel (SAE 1070, 1095)

Application: Used for manufacturing springs, suspension components, and other parts requiring high yield strength and elasticity.

10. Electrical Steel (Grain Oriented and Non-Grain Oriented)

Application: Used in transformers, motors, and generators due to its magnetic properties and low core loss.

These grades represent a range of steel types tailored to specific applications, each offering unique properties such as strength, corrosion resistance, machinability, and electrical conductivity.
