What is 310 Stainless Steel?

310 stainless steel is an austenitic heat-resistant alloy made up mostly of 25% chromium and 20% nickel, making it one of the most oxidation and scale resistant stainless steels available. It retains its strength and corrosion resistance even when exposed to temperatures beyond 1000°C (1832°F).

 

Designed for cyclic heating conditions, 310 performs well in both oxidizing and moderately reducing environments, making it appropriate for components that are subjected to repeated thermal cycling and corrosive industrial environments.

 

Key Features 

  • High-Temperature Strength
    Excellent resistance to creep, scaling, and high-temperature corrosion.

  • Superior Oxidation Resistance
    Resists oxidation in air up to 1150°C (2102°F) under intermittent exposure.

  • Non-Magnetic in Annealed State
    Slight magnetism may develop after cold working.

  • Good Resistance to Sulfidation and Carburization
    Performs well in environments rich in sulfur and carbon.

  • Excellent Fabrication & Weldability
    Easily formed, welded, and fabricated into complex structures.

  • ASTM A240 / EN 1.4845 Compliant
    Meets global industrial standards for pressure and thermal systems.

Corrosion Resistance

  • Oxidation Resistance: Thanks to its high chromium content (about 25%), Stainless Steel Plate 310 offers excellent resistance to oxidation, especially at high temperatures. It can withstand environments up to 2100°F (1149°C) without significant degradation, making it suitable for furnace components and high-heat applications.
  • Sulfuric Acid Resistance: While not as resistant as some other alloys, Stainless Steel Plate 310 provides good resistance to sulfuric acid in dilute concentrations and at moderate temperatures, which is beneficial in certain chemical processing environments.
  • Chloride Stress Corrosion Cracking (SCC): The alloy has moderate resistance to chloride-induced stress corrosion cracking, though it is not as resistant as some other grades specifically designed for this purpose, such as 316L.
  • Corrosion in Acidic Environments: Stainless Steel Plate 310 offers some resistance to acids, including nitric acid, but may require additional protective measures or coatings in highly aggressive acid environments to ensure optimal performance.
  • General Corrosion Resistance: The high nickel content (about 20%) helps to enhance resistance against general corrosion, including atmospheric corrosion and various industrial chemicals, providing a broad spectrum of protection.

Fabrication Data

  1. Cutting
  • Laser Cutting: Provides high precision and clean edges. Suitable for intricate designs and thick plates.
  • Water Jet Cutting: Effective for cutting thick plates without affecting the material properties due to heat.
  • Plasma Cutting: Fast and cost-effective for thicker plates, though it may produce rougher edges compared to laser cutting.
  • Shearing: Suitable for straight cuts in thinner plates.
  1. Machining
  • Drilling: Use carbide-tipped drill bits or cobalt drills. Stainless steel can work-harden, so cutting speeds and feeds should be optimized.
  • Milling: Use high-speed steel (HSS) or carbide tools. Ensure proper cooling and lubrication to manage heat buildup.
  • Turning: Similar to milling, with attention to cutting speeds and tool materials to prevent work hardening.
  1. Welding
  • TIG (Tungsten Inert Gas) Welding: Preferred for its precision and ability to produce clean, high-quality welds. Use filler rods compatible with grade 310.
  • MIG (Metal Inert Gas) Welding: Can be used for larger welds or where speed is a factor. Ensure proper shielding gas and filler materials.
  • Resistance Welding: Suitable for certain applications where fast, high-volume welding is required.
  1. Bending and Forming
  • Press Brake Bending: Effective for creating precise angles and bends. Proper tooling and die selection are crucial to prevent cracking.
  • Roll Forming: Suitable for creating long, continuous curves or shapes.
  1. Heat Treatment
  • Annealing: Helps to relieve stresses and enhance ductility. Stainless steel 310 should be annealed at temperatures between 1040°C to 1150°C (1900°F to 2100°F).
  • Solution Treatment: Involves heating the material to a high temperature and then rapidly cooling to achieve optimal mechanical properties.
  1. Surface Finishing
  • Grinding and Polishing: To achieve a smooth finish or specific surface texture. Use appropriate abrasives and polishing compounds for stainless steel.
  • Passivation: Enhances corrosion resistance by removing free iron and other contaminants from the surface.
  1. Drilling and Tapping
  • Drilling: Use carbide drills and ensure proper cooling to prevent work hardening.
  • Tapping: Utilize taps designed for stainless steel and ensure lubrication to ease the tapping process.
  1. Assembly and Joining
  • Bolting: Common for assemblies where disassembly may be needed. Ensure bolts and fasteners are compatible with stainless steel.
  • Adhesive Bonding: For applications where welding or mechanical fastening is not feasible.
