14 Steel Types and What Makes Them Work in Wholesale Projects
1. Carbon Steel
Application: Pressed components, powder-coated enclosures
Composition: 0.05–1.0% C; low alloy content
Engineering Note: 400–900 MPa tensile strength. Ideal for sheet processing and CNC cutting. Requires a coated finish to resist oxidation.
2. Alloy Steel (4130 & 4140)
Use: Automotive components, fixtures, laser-cut signs
4130 Properties: Tensile ~670 MPa; excellent weldability
4140 Properties: Rockwell hardness up to 95 HRB; yield ~655 MPa
Engineering Note: Tensile strength of up to 1200 MPa after quenching. Ideal for fatigue-critical shafts and tube bending.
2. Alloy Steel (4130 & 4140)
Use: Automotive components, fixtures, laser-cut signs
4130 Properties: Tensile ~670 MPa; excellent weldability
4140 Properties: Rockwell hardness up to 95 HRB; yield ~655 MPa
Engineering Note: Tensile strength of up to 1200 MPa after quenching. Ideal for fatigue-critical shafts and tube bending.
3. Stainless Steel – 304 & 316 Grades
Use: Medical trays, industrial sinks, patio furniture frames
304 Stainless Steel Strength: ~505 MPa; yield ~215 MPa; heat resistance to 870 °C
316 Stainless Steel Strength: ~515 MPa; yield ~290 MPa; superior chloride resistance
Finishes: Brushed, mirror, or powder coating for stainless steel (e.g., powder coat stainless steel patio furniture)
Engineering Note: Non-magnetic; excellent corrosion resistance; frequently used in laser cutting applications.
4. Tool Steel
Used for: Dies, drill bits, lathe tooling
Performance: 60–65 HRC hardness (D2, M2 grades)
Engineering Note: High abrasion resistance; accepts powder coating post-machining for enhanced protection.
5. Tungsten Steel
Use Case: Aerospace turbine cutters, high-speed mill inserts
Key Feature: Retains red hardness above 600°C; often alloyed with cobalt for high-speed steel tooling.
6. Nickel Steel
Used in: Cryogenic tanks, impact-resistant housings
Engineering Note: Offers toughness up to 1000 MPa; ideal for sub-zero applications and heavy structural frames.
7. Manganese Steel
Ideal for: Quarry linings, rail frogs, impact plates
Attributes: Self-hardens under impact; highly wear-resistant when cast to shape.
8. Vanadium Steel
Used for: Engine rods, vibration-prone components
Engineering Note: Grain refinement yields excellent fatigue life; compatible with sheet metal forming equipment.
9. Chromium Steel
Used in: Decorative trims, elevator panels, architectural facades
Finishing: Nitriding, hard chrome plating, or coating for durability and shine.
10. Chromium-Vanadium Steel
Application: Forged hand tools, socket sets, automotive springs
Engineering Note: Balanced hardness and elasticity; drop-forged then coated for improved resistance to fatigue.
11. Silicon Steel
Primary Use: Transformer cores, motor stators
Grades: Grain-oriented to reduce core losses; non-oriented for rotating machinery.
12. Molybdenum Steel
Best For: Boilers, pressure vessels, high-temperature enclosures
Engineering Note: Stable up to 500–600 °C; often included in chrome-moly alloys.
13. Cobalt Steel
Ideal in: Aerospace tooling, surgical drills
Specs: Retains hardness at temperatures up to 1100 °C (M35/M42 HSS); ideal for cutting tool blanks.
14. Aluminum Steel
Used in: Solar frames, signage systems, lightweight enclosures
Engineering Note: 10% Al reduces density; excellent for coated galvanized metals and anodizing.
