Breaking Boundaries: Can Modern Fiber Lasers Really Cut 30mm Stainless Steel? [2024 Guide]

The Evolution of Thick-Plate Laser Cutting Technology

In the rapidly evolving world of metal fabrication, the capability to cut thick stainless steel has become a game-changing benchmark. As a veteran with 30 years of experience at Tianchen Laser, I've witnessed firsthand the remarkable transformation of laser cutting technology, particularly in handling thick materials. Modern fiber laser systems have indeed revolutionized our approach to cutting thick stainless steel, achieving what was once considered impossible.

Understanding Thick-Plate Cutting Capabilities

Power and Precision: The New Generation

Today's advanced fiber laser systems, particularly those equipped with power outputs ranging from 15kW to 30kW, have dramatically expanded the possibilities in thick-plate cutting. These machines can effectively process stainless steel up to 30mm thick while maintaining exceptional edge quality and precision. The key lies in the perfect combination of high power density and advanced beam control systems.

Real-World Performance Metrics

In industrial applications, modern fiber laser systems demonstrate remarkable capabilities:

• Cutting speeds of up to 0.8 meters per minute in 30mm stainless steel

• Edge roughness values below Ra 3.2 μm

• Minimal heat-affected zone (HAZ)

• Dross-free cuts with nitrogen assistance
