Product Description

AISI O1 Tool Steel /1.2510/100MnCrW4/SKS3  steel Overview:
O1 steel is a general-purpose oil-hardening tool steel known for its excellent combination of toughness, wear resistance, and machinability. It belongs to the group of oil-hardening steels and is commonly used in various applications requiring good dimensional stability, sharp cutting edges, and ease of heat treatment.

Chemical Composition:

C(%)	Si(%)	Mn(%)	Cr(%)	W(%)	V(%)	P(%)	S(%)
0.85-1.00	0.10-0.50	1.00-1.40	0.40-0.60	0.40-0.60	0.20-0.30	≤0.030	≤0.030

Properties:
1.High Hardness: O1 steel can achieve high hardness levels through proper heat treatment, providing excellent wear resistance and edge retention.
2.Good Toughness: Despite its high hardness, O1 steel exhibits good toughness, allowing it to withstand impact and shock loading without chipping or breaking.
3.Excellent Machinability: O1 steel is easy to machine, making it suitable for manufacturing processes such as milling, turning, drilling, and grinding.
4.Dimensional Stability: The alloy composition of O1 steel provides it with good dimensional stability during heat treatment, minimizing the risk of distortion or dimensional changes.
5.Fine Grain Structure: O1 steel typically exhibits a fine grain structure, contributing to improved toughness and edge sharpness.

Applications:
1.Cutting Tools: O1 steel is widely used for manufacturing cutting tools such as knives, blades, razors, and shears used in woodworking, metalworking, and other industries.
2.Punches and Dies: It finds application in the production of punches, dies, and blanking tools used for cutting, stamping, and forming sheet metal and other materials.
3.Forming Tools: O1 steel is utilized in the manufacturing of forming tools such as bending dies, embossing dies, and extrusion tools used in metal forming processes.
4.Molds and Dies: It is employed in the production of molds and dies for injection molding, compression molding, and other molding processes requiring good wear resistance and dimensional stability.
5.Thread Cutting Tools: O1 steel is used for manufacturing thread cutting tools such as taps and dies used for threading bolts, screws, and other threaded components.

Heat Treatment:
Annealing: Heat uniformly to 750-800°C (1382-1472°F), soak for sufficient time, then slowly cool in the furnace or in air to room temperature to achieve a soft and machinable structure.
Hardening: Heat slowly to the austenitizing temperature of 780-820°C (1436-1508°F), soak for sufficient time, then quench in oil to achieve full hardness.
Tempering: Temper immediately after quenching at 150-300°C (302-572°F) depending on the desired hardness and toughness requirements, hold for sufficient time, then cool in air.

Surface Treatment:
Surface Coatings: Various surface coatings such as TiN (Titanium Nitride) and DLC (Diamond-Like Carbon) can be applied to improve the surface hardness, reduce friction, and enhance wear resistance.

Quality Assurance:
Certifications: Manufacturers of O1 steel often adhere to international quality standards such as ISO 9001 to ensure the quality and consistency of their products.
Testing: Quality control measures include chemical composition analysis, mechanical property testing, and non-destructive testing to ensure compliance with specifications and customer requirements.

Environmental Considerations:
Recyclability: O1 steel is recyclable and can be reclaimed and reused at the end of its service life, contributing to sustainability and environmental responsibility in manufacturing processes.
