S100N is a high carbon steel powder with spheroid particles of about 250 microns.
Low-carbon steel consists of less than 0.30% carbon. Medium-carbon steel consists of 0.30% to 0.60% carbon. And high-carbon steel contains more than 0.60% carbon. As the carbon content of steel increases, it becomes stronger and harder.

S100N Applications include:
S100N is a hard, rust resistant iron/ steel powder mesh 100. Iron Steel Powder Mesh 100
S100N Applications include:
- Filler metal in welding cast iron and cast steel
- Iron Filing for electromagnetism experiments and magnetic field demonstrations.
- Soil Additive (slow release of iron ions)
- Cold casting/ Resin casting (To increase the density or make the product attractable to magnets and detectable by metal detectors).
- Concrete (Added for weight enhancement, magnetic properties, creating rust effects)
- Fireworks (an ingredient of sparklers)
- Sand blasting
- Abrasives
- Chemical reactions (making iron sulfate, Producing hydrogen gas)
- Textured floor paints
Do Not Use For: Metal Clays, sintered products, Food products.
View under microscope
The 20X magnification image of S100N indicate a narrow cut of about 250 micron particles. No more than 5% of the particles have a length that is in excess of twice the cross section. No more than 15% of the particles have a microscopic crack. No more than 10% of particles contain shrinkage. Particles are as nearly spherical as commercially possible and no more than 20% of the particles have objectionable defects.

Description
Coarse steel powder (S100N) is produced from recycled black steel (construction steel) with improved features like dust-free, equal-size, and mostly spherical particles. It demonstrates strong magnetic attraction, has a high flow rate for dispensing from shakers, and is free from organic impurities such as cutting oil. This product is ideal for educational and industrial applications, including magnetism experiments, rust effect creation, and as a plant nutrient for iron supplementation.
Applications and Benefits
- Used as iron filings for magnetism and electromagnetism experiments
- Preferred for educational use due to cleanliness and contamination-free particles
- Creates rust effects in sculptures, concrete, and structures
- Serves as a plant nutrient for iron supplementation
- High flow rate makes it suitable for dispensing from shakers
