Laser Cutting 310S Stainless Steel Plate in Square , Round , Circle Shapes Hot Rolled Thickness 3.0 - 40.0mm

Laser Cutting 310S Stainless Steel Plate in Square, Round, Circle Shapes – Hot Rolled, Thickness 3.0–40.0mm

Overview

310S stainless steel is a high-alloy austenitic stainless steel renowned for its exceptional resistance to oxidation, corrosion, and high-temperature environments. With a composition of approximately 25% chromium and 20% nickel, it offers superior creep strength and thermal stability, making it ideal for applications that demand performance under extreme heat—up to 1035°C (1900°F).

At our facility, we specialize in precision laser cutting of 310S stainless steel plates into custom square, round, and circular shapes, tailored to your exact specifications. Our hot-rolled plates range in thickness from 3.0 mm to 40.0 mm, ensuring suitability for both structural and high-performance industrial components.

Whether you're in aerospace, petrochemical processing, furnace manufacturing, or power generation, our laser-cut 310S stainless steel parts deliver reliability, dimensional accuracy, and long-term durability—even in the most aggressive operating conditions.

Key Features & Benefits

Chemical Composition (ASTM A240 / UNS S31008)

This balanced composition ensures optimal high-temperature strength without compromising corrosion resistance in oxidizing atmospheres.

Mechanical Properties (Typical Values, Annealed Condition)

These properties make 310S not only heat-resistant but also ductile enough for forming and fabrication after laser cutting.

Why Choose Laser Cutting for 310S Stainless Steel?

Laser cutting is the preferred method for processing high-alloy stainless steels like 310S due to its:

• Non-contact process: Eliminates mechanical distortion, crucial for maintaining flatness in thin to medium plates (3–20 mm).
• High precision: Achieves intricate contours, small holes, and tight radii without secondary finishing.
• Clean cut edges: Minimal heat-affected zone (HAZ), preserving the material’s corrosion resistance near cut lines.
• Rapid prototyping & production: Digital nesting software maximizes material utilization and reduces waste—ideal for both one-off prototypes and batch orders.
• Scalability: From single pieces to high-volume runs, laser systems adapt seamlessly.

Our fiber laser systems are calibrated specifically for thick-section 310S (up to 40 mm), using nitrogen-assisted cutting to prevent oxide formation and ensure bright, weld-ready edges.

Available Dimensions & Tolerances

We offer hot-rolled 310S stainless steel plates in the following standard and custom dimensions:

All plates undergo ultrasonic testing (optional) and visual inspection before cutting to ensure freedom from laminations, cracks, or inclusions.

Common Applications

Thanks to its dual capability as both a corrosion-resistant alloy and a high-temperature structural material, laser-cut 310S components are widely used in:

• Industrial Furnaces: Radiant tubes, muffles, retorts, burner nozzles
• Heat Treatment Equipment: Trays, baskets, fixtures
• Exhaust Systems: Automotive and marine exhaust manifolds, catalytic converter housings
• Chemical Processing: Reactor linings, piping supports, valve bodies
• Power Generation: Boiler components, superheater tubes, flue gas ducts
• Aerospace: Jet engine parts, afterburner components
• Waste Incineration: Grates, combustion chambers

Circular and ring-shaped laser-cut parts are especially popular for flanges, sealing rings, and rotary kiln components where thermal cycling is frequent.

Ordering Guide: How to Specify Your 310S Laser-Cut Parts

To ensure fast and accurate quoting and production, please provide:

1. Material Specification: Confirm 310S (S31008) grade
2. Plate Thickness: e.g., 6.0 mm, 12.5 mm, 25.0 mm
3. Shape & Dimensions:
   • Square: e.g., 300 × 300 mm
   • Round/Circle: e.g., Ø500 mm
   • Include hole patterns, inner diameters (for rings), or CAD files (DXF, DWG)
4. Quantity: From 1 piece to 1000+ units
5. Tolerance Requirements: Standard or tighter (e.g., ±0.05 mm)
6. Edge/Finish Preference: As-cut, deburred, brushed, or pickled
7. Certification Needs: Mill Test Report (MTR) per EN 10204 3.1, ASTM, or ISO

We support just-in-time delivery and can package parts with anti-corrosion paper for overseas shipping.

Advantages Over Competing Alloys

For most industrial heating applications below 1050°C, 310S offers the best value-to-performance ratio—especially when precision laser cutting is required.

Sustainability & Recyclability

310S stainless steel is 100% recyclable. Our laser cutting process generates minimal scrap, and all offcuts are collected for remelting. By choosing laser over plasma or oxy-fuel cutting, you also reduce energy consumption and emissions—supporting greener manufacturing practices.

Conclusion

When your application demands uncompromising performance in high-heat, corrosive environments, 310S stainless steel is the material of choice. Combined with advanced laser cutting technology, we transform raw hot-rolled plates (3–40 mm thick) into precision-engineered square, round, and circular components that meet the strictest industrial standards.

Backed by full material traceability, ISO-certified processes, and decades of metallurgical expertise, we ensure every part delivers consistent quality, dimensional accuracy, and long service life.
