Flame Cutting

At SLM Metal, we specialize in manufacturing high-quality iron powders that meet the demanding requirements of advanced industrial processes. One of the most critical applications of our powders is in flame cutting, particularly for stainless steels and alloy steels where traditional oxy-fuel cutting methods face limitations.

The Role of Iron Powder in Flame Cutting

Flame cutting of stainless steels, tool steels, and other high-alloy steels presents significant challenges. Unlike carbon steels, these alloys resist oxidation and require additional heat to achieve clean, efficient cuts. This is where iron powder becomes indispensable.

When introduced into the cutting zone, iron powder undergoes an exothermic reaction with oxygen. This reaction releases intense localized heat, which:

1. Raises the cutting temperature beyond what the oxy-fuel flame alone can provide.

2. Assists in breaking down the alloying elements (such as chromium and nickel) that normally resist cutting.

3. Promotes efficient slag removal, ensuring smoother cuts with minimal defects.

This synergy enables flame cutting of alloys that would otherwise be difficult—or nearly impossible—to process using conventional methods.

Key Requirements for Cutting-Grade Iron Powder

To achieve consistent results, iron powder for flame cutting must possess specific properties:

• High Purity: Prevents contamination of cut surfaces and ensures stable reactions.

• Controlled Particle Size Distribution: Delivers uniform flow, consistent reaction rates, and predictable cutting performance.

• Excellent Flowability: Ensures smooth feeding through delivery systems without clogging.

• Thermal Stability: Maintains reactivity and performance at high cutting temperatures.

At SLM Metal, our SLM100.29C grade iron powder is carefully engineered with these exact requirements, making it a trusted choice for flame cutting applications worldwide.

Benefits for Manufacturers and End Users

Using high-quality iron powder in flame cutting provides several advantages:

• Cleaner Cuts – Reduced dross and slag formation lead to improved surface finish.

• Increased Productivity – Faster cutting speeds reduce processing times.

• Reduced Consumable Wear – Optimized powder reduces nozzle wear and extends equipment life.

• Cost Efficiency – Better yield and reduced rework lower overall operating costs.

Applications in Industry

Iron powder-assisted flame cutting is widely used in:

• Stainless steel slab, bloom, and billet processing in steel plants.

• Heavy alloy steel cutting for shipbuilding, oil & gas, and infrastructure projects.

• Tool steel and wear-resistant alloy cutting, where precision and consistency are critical.
