Product Description

AISI 1074/1075 Steel
1074 steel is a high-carbon steel alloy that is commonly used in various industrial applications due to its excellent strength, hardness, and wear resistance properties. It is a type of spring steel known for its ability to withstand high stress and repeated impacts.

Composition
The chemical composition of 1074 steel typically includes:
·Carbon (C): 0.70% - 0.80%
·Manganese (Mn): 0.50% - 0.80%
·Phosphorus (P): 0.035% max
·Sulfur (S): 0.040% max
The high carbon content gives 1074 steel its characteristic hardness and strength, while manganese enhances its toughness and hardenability.

Mechanical Properties
The mechanical properties of 1074 steel depend on factors such as heat treatment, processing, and alloying elements. However, typical mechanical properties for 1074 steel in the annealed or normalized condition are:
·Tensile Strength: 685 MPa (99,400 psi) - 725 MPa (105,100 psi)
·Yield Strength: 515 MPa (74,800 psi) - 580 MPa (84,100 psi)
·Elongation: 7% - 15%
·Reduction of Area: 30% - 40%
·Hardness: 197 HB - 229 HB
·Weldability: Fair weldability when properly preheated and welded, requiring post-weld heat treatment.
·Machinability: Relatively poor machinability in hardened state; suitable for machining in annealed or normalized condition.
·Corrosion Resistance: Susceptible to rusting and corrosion; requires surface protection in corrosive environments.
·Formability: Can be cold worked and formed using conventional processes such as bending and stamping.

Heat Treatment
1074 steel can be heat treated to achieve desired mechanical properties. Common heat treatment processes include:
·Annealing: Heating the steel to around 800°C (1470°F) and slow cooling in the furnace to relieve internal stresses and improve machinability.
·Normalizing: Heating the steel to around 870°C (1600°F) and air cooling to refine the grain structure and improve mechanical properties.
·Quenching and Tempering: Heating the steel to around 820°C (1500°F), quenching in oil or water, and then tempering at a specific temperature to achieve the desired combination of hardness and toughness.

Surface Finish
1074 steel is typically supplied in the annealed, normalized, or hardened and tempered condition with a smooth surface finish. It can undergo additional surface treatments, such as shot blasting or polishing, to improve surface quality and appearance.

Applications
1074 steel is widely used in various industrial applications where high strength, hardness, and wear resistance are required. Common applications include:
·Springs and suspension components in automotive and transportation systems
·Cutting tools and blades for metalworking, woodworking, and fabrication
·Hand tools and agricultural implements requiring durability and toughness
·Machinery and equipment components subjected to high stress and wear conditions
·Structural components in construction, infrastructure, and machinery
