Not all steel is cut the same way. From Cold Rolled (CR) to Stainless Steel (SS) and Silicon Steel (CRGO), each material has unique properties that influence cutting precision and machine performance. Using a standard shearing machine without considering the steel type can result in burrs, edge deformation, or even blade damage.
In this guide, we focus on how Leo Engineers’ steel shearing machines—pneumatic and foot-pedal operated—handle different steel grades more efficiently than conventional options.
1. Understanding Steel Grades in Shearing
Mild Steel (MS)
Easy to shear due to lower tensile strength.
Requires sharp blades to avoid edge deformation.
Ideal for workshops handling general MS sheets under 3mm.
Stainless Steel (SS)
Harder and more abrasion-resistant than MS.
Needs rigid machine frames to avoid blade spring or distortion.
Our HCHCR blades ensure clean, burr-free edges even under repetitive cuts.
Silicon Steel / CRGO
Used in transformers and electrical equipment.
Extremely sensitive to edge quality; even minor burrs affect performance.
Requires precise cutting with minimal mechanical stress.
➡ Pro Tip: Selecting the right shearing machine for steel starts with identifying your sheet type and thickness.
Contrary to popular belief, hydraulic shears are not always necessary for steel under 3mm. Pneumatic and foot-pedal machines offer advantages:
The Impact Factor
Pneumatic machines use high-velocity air pressure to snap steel cleanly.
Produces smoother edges compared to slow, crushing hydraulic shears.
Especially effective for Stainless Steel sheets, reducing rework.
The Control Factor
Foot pedal shears give operators full alignment control before cutting.
Critical for expensive materials where mistakes are costly.
Allows precise, consistent placement for repeatable results.
3. Critical Feature: The HCHCR Blade Advantage
Your blades are the biggest investment in shearing steel:
Material: High Carbon High Chromium (HCHCR) for wear resistance.
Heat-Treated: Edge remains sharper 4x longer than standard carbon steel blades.
Durability: Handles abrasive materials like CR, SS, and CRGO without frequent resharpening.
Leo Engineers Pro-Tip: Always match blade hardness with steel grade. For SS or CRGO, HCHCR is non-negotiable for clean edges and machine longevity.
Industrial Applications: Steel Grades We Support
Our machines are engineered to handle the specific stresses of various industrial steels. Whether you are a small workshop or a large-scale manufacturer, choosing a machine based on your material is the first step to quality.
1. Stainless Steel & Mild Steel Solutions
Cutting Stainless Steel (SS) requires a machine that can handle high shear resistance without blade deflection. Our pneumatic and foot-operated machines are the preferred choice for:
SS sheet shearing for kitchenware and medical equipment.
MS sheet shearing for general cabinet and panel fabrication.
Looking for a competitive stainless steel sheet cutting machine price? Our direct-manufacturer model ensures you get industrial quality without the retail markup.
2. Precision Silicon Steel (CRGO) Cutting
Transformer manufacturers require extreme precision to maintain the magnetic properties of CRGO (Cold Rolled Grain Oriented) steel. Our precision steel shears are designed to provide the burr-free edges necessary for:
CRGO cutting machines for transformers
High-efficiency electrical laminations
Which Steel Shearing Machine is Right for You?
Depending on your production volume and the thickness of your material, we offer two primary “Steel Specialist” machine types:
Pneumatic Steel Shearing Machine: Best for high-speed, repetitive MS and SS sheet cutting where air-powered automation is required.
Foot Operated Steel Cutter: The most cost-effective solution for precision workshops that need a “Zero-Electricity” steel shearing tool.

Conclusion: Material Drives Machine Choice
Choosing the right steel shearing machine isn’t just about horsepower or speed. Your material—whether CR, SS, or CRGO—dictates the type of machine, blade, and control method.
Leo Engineers’ pneumatic and foot-pedal steel shearing machines are optimized for precision, minimal edge deformation, and material-specific handling. When you pair the right steel with the right machine, your workshop can achieve burr-free, accurate cuts every time.
