Key properties and advantages of S2 powder:

S2 Powder Properties and Characteristics

S2 powder produces cutting tools, dies, and machine components with extended service life under continuous high temperature and intermittent shock loading conditions.

S2 Powder Composition

Iron provides the ferritic matrix

Carbon, tungsten, and chromium form hard carbides

Vanadium and molybdenum enhance wear resistance

Manganese and silicon facilitate machining

S2 Powder Physical Properties

High density enables miniaturized components

Retains hardness and strength at elevated temperatures

Becomes paramagnetic above Curie point

Can withstand prolonged service up to 600°C

Good thermal conductivity reduces thermal expansion stresses

These properties provide a balanced combination of hot hardness and thermal shock resistance required in high speed machining applications.

S2 Powder Mechanical Properties

Exceptional hardness when heat treated

High strength with reasonable ductility

Very good compressive and transverse rupture strength

Excellent red hardness at elevated temperatures

Strength depends on heat treatment process

S2 powder produces cutting tools and dies with hardness, strength, and thermal properties needed to machine challenging materials at high speeds and temperatures.

S2 Powder Applications

Some specific product uses:

Cutting inserts, indexable tooling

Broaches, reamers, taps, threading dies

Metal slitting saws and industrial knives

Extrusion tooling and drawing dies

Cold heading and forging dies

Gauges, wear-resistant components

S2’s unique properties make it the top choice for reliable cutting tools and components used in demanding metalworking applications.

S2 Powder Standards

These define:

Chemical composition limits of S2

Required mechanical properties in heat treated condition

Approved production methods like gas atomization

Compliance testing protocols

Quality assurance requirements

Proper packaging and identification

Powder produced to these standards ensures suitability for high wear resistance tooling applications under thermal fatigue conditions.

S2 Powder Particle Size Distribution

Finer particles allow greater densification during sintering

Coarser particles improve powder flow into die cavities

Size is selected based on final part properties needed

Both gas and water atomized particles used

Controlling size distribution optimizes pressing behavior, sintered density, and final component performance.

S2 Powder Apparent Density

Spherical powder shape provides high apparent density

Irregular powder has lower density around 45-50%

Higher apparent density improves die filling and part quality

Allows complex tool geometry compaction

Higher apparent density leads to better component production rate and performance.

S2 Powder Production Method

Gas atomization provides spherical powder shape

Vacuum melting eliminates gaseous impurities

Multiple remelting improves uniformity

Post-processing allows particle size customization

Fully automated processes combined with strict quality control ensures reliable and consistent S2 powder properties critical for tooling performance.

S2 Powder Handling and Storage

Storage Recommendations

Store sealed containers away from moisture or contamination

Maintain storage temperatures below 27°C

Limit exposure to oxidizing acids and chlorine compounds

Proper precautions during handling and storage help preserve purity and prevent safety hazards.

S2 Powder Inspection and Testing

Testing ensures the powder meets the required chemical composition, physical characteristics, particle size distribution, morphology, density, and flow rate specifications.

S2 Powder Pros and Cons

Advantages of S2 Powder

Exceptional hot hardness and red hardness

S2 Powder FAQs

Q: What are the main applications of S2 tool steel powder?

A: Main applications include cutting tools like drills, mills, inserts, taps, dies, saws, planing tools, as well as extrusion tooling, forging dies, gauges, and components needing hot hardness and thermal shock resistance.

Q: What heat treatment is used for S2 tool steel powder?

A: S2 tool steel is typically heat treated by austenitizing between 1150-1200°C followed by air, oil, or polymer quenching, then tempering between 540-650°C to achieve hardness between 62-64 HRC.

Q: How does tungsten improve the properties of S2 steel?

A: Tungsten forms hard tungsten-iron-carbon complexes that provide exceptional hot hardness, strength and wear resistance at elevated temperatures needed for high speed machining applications.

Q: What safety precautions should be used when working with S2 powder?

A: Proper ventilation, protective gear, inert atmosphere, grounding, avoiding ignition sources, using non-sparking tools, and safe storage away from contamination or moisture.
