Product Description

AISI 1080 High Carbon Steel:
1080 steel is a high carbon steel known for its excellent strength, hardness, and wear resistance. It belongs to the class of carbon steels with a carbon content ranging from 0.75% to 0.88%. 1080 steel finds applications in various industries where toughness and durability are critical, such as blades, springs, and hand tools.

Chemical Composition:
Carbon (C): 0.75%-0.88%
Manganese (Mn): 0.60%-0.90%
Phosphorus (P): 0.040% (max)
Sulfur (S): 0.050% (max)

Mechanical Properties:
Hardness: 55-60 HRC (Rockwell C scale)
Tensile Strength: 725-850 MPa (105,000-123,000 psi)
Yield Strength: 620 MPa (90,000 psi) (approximate)
Elongation: 10%-15% (in 50mm)

Physical Properties:
Density: 7.85 g/cm³ (0.284 lb/in³)
Melting Point: Approximately 1425°C (2600°F)

Heat Treatment:
1080 steel can be hardened and tempered to achieve desired mechanical properties. Common heat treatment processes include:
Quenching: Heating to austenitizing temperature (815°C - 870°C or 1500°F - 1600°F) followed by rapid quenching in oil or water to achieve maximum hardness.
Tempering: Reheating to a specific temperature (usually between 370°C - 500°C or 700°F - 930°F) to reduce brittleness and improve toughness while retaining hardness.

Surface Treatment:
Surface treatments for 1080 steel include:
Polishing: Enhances appearance and improves corrosion resistance.
Black oxide coating: Provides a protective layer against corrosion and wear.
Satin or brushed finish: Adds aesthetic appeal and reduces glare.

Applications:
Blades: Hunting knives, machetes, and swords.
Springs: Coil springs, flat springs, and leaf springs.
Hand tools: Chisels, punches, and woodworking tools.
Automotive components: Leaf spring clips, washers, and brackets.

Quality Assurance:
1080 steel is typically produced to industry standards such as ASTM A29 and SAE J403. Quality assurance measures include chemical composition analysis, mechanical property testing, and dimensional inspection.

Environmental Considerations:
Proper disposal of cutting fluids and other waste products generated during machining and heat treatment processes is essential to minimize environmental impact. Recycling of scrap steel is encouraged to conserve resources and reduce energy consumption.
