Our Small Tolerance Stainless Steel Plates are engineered for precision-critical applications, offering thicknesses from 0.1mm to 30.0mm and widths including 1000mm, 1219mm, 1500mm, 1800mm, and 2000mm. Manufactured with tight dimensional tolerances, these plates ensure consistent thickness and flatness, minimizing material waste and enhancing compatibility with high-precision fabrication processes. Available in both hot-rolled and cold-rolled finishes, they combine the inherent corrosion resistance of stainless steel with superior mechanical properties, making them ideal for industries where accuracy and reliability are non-negotiable.
Common Grades
Austenitic Grades
304/304L: Balances excellent corrosion resistance in mild environments (e.g., atmospheric, food-grade) with good formability and weldability. 304L (low carbon) reduces carbide precipitation risk during welding.
316/316L: Offers superior resistance to chloride-induced corrosion, making them suitable for marine, pharmaceutical, and chemical processing applications. 316L minimizes intergranular corrosion in welded structures.
321/347: Stabilized with titanium (321) or niobium (347) to prevent carbide precipitation at high temperatures, ideal for components in furnaces, exhaust systems, and thermal equipment.
Duplex & Super Duplex Grades
2205: Combines high strength (double that of austenitic grades) with excellent stress corrosion cracking resistance, used in oil & gas, seawater handling, and pressure vessels.
2507: A super duplex grade for extreme environments, offering superior resistance to pitting, crevice corrosion, and high-pressure applications like offshore platforms.
Martensitic & Ferritic Grades
430: Magnetic, cost-effective, and resistant to atmospheric corrosion, commonly used in architectural trims, automotive exhausts, and heat-resistant applications.
410/420: Hardenable grades with moderate to high hardness (after heat treatment), suitable for knife blades, pump shafts, and mechanical parts requiring wear resistance.
Standards Compliance
These plates adhere to international standards for dimensional accuracy and material performance:
ASTM A240/A240M: Defines chemical composition, mechanical properties (tensile strength, elongation), and tolerance requirements for stainless steel plates.
EN 10088-2/EN 10029: European standards specifying technical delivery conditions for flat products, including strict tolerances for thickness, width, and flatness.
JIS G4305 (Cold-Rolled) / JIS G4304 (Hot-Rolled): Japanese standards ensuring surface quality and dimensional precision for industrial and structural applications.
GB/T 3280 (China): Mandates tight tolerances for high-precision stainless steel plates used in aerospace, electronics, and medical devices.
Processing Services
Precision Cutting
Laser Cutting: Achieves micron-level accuracy for complex shapes, ideal for thin plates (0.1–5mm) in electronics and medical devices.
Waterjet Cutting: Cuts thick plates (up to 30mm) without heat-affected zones, preserving material properties for aerospace and defense components.
Shearing/Plasma Cutting: Cost-effective solutions for large-scale production, ensuring straight edges and tight width tolerances.
Forming & Fabrication
Press Bending: High-precision CNC press brakes form plates into channels, angles, or custom profiles with minimal springback, suitable for structural frames and machine enclosures.
Welding: TIG/MIG welding services for austenitic and duplex grades, with post-weld heat treatment (when required) to maintain dimensional stability and corrosion resistance.
Surface Finishing
Polishing (2B, BA, Mirror): Enhances aesthetic appeal and hygiene for food processing or architectural applications.
Passivation/Pickling: Removes surface contaminants and strengthens the protective oxide layer, improving corrosion resistance for marine or chemical environments.
Embossing/Pattern Rolling: Adds anti-slip textures or decorative patterns for flooring, stair treads, and signage.
Key Advantages
Ultra-Tight Tolerances: Thickness tolerances as low as ±0.01mm (for thin plates) and ±0.1% (for thick plates), meeting ISO 683-13 and ASME BPVC Section II requirements for critical applications.
Material Versatility: Available in 20+ grades, covering corrosion resistance, high-temperature stability, and extreme strength needs across industries.
Surface Quality: Cold-rolled plates offer superior flatness (≤2mm/m) and surface roughness (Ra ≤1.6μm), reducing post-processing efforts for precision components.
Inventory Flexibility: Wide stock of standard widths and thicknesses, with quick turnaround for custom orders to minimize project delays.
Traceability & Certification: Full material traceability from mill to delivery, with mill test reports (MTR), PMI certificates, and NDT (ultrasonic/eddy current) reports available upon request.
Applications
Aerospace & Defense
Wing ribs, fuselage panels, and engine components (321/347 for heat resistance; 2205 for lightweight strength).
Armor plating and missile parts requiring high impact resistance and dimensional precision.
Medical & Biotechnology
Surgical instrument trays (316L for biocompatibility), diagnostic equipment enclosures, and implantable device components (polished surface for hygiene).
Electronics & Semiconductors
Precision shims, heat sinks, and circuit board frames (0.1–1mm thickness with ±0.02mm tolerance for microelectronics).
Cleanroom-compatible panels resistant to chemical cleaning agents.
Industrial Equipment
Heat exchanger plates (316L/2205 for corrosion resistance), pump casings, and robotic arm components (420 for wear resistance).
Precision machine bases and guides requiring minimal thermal expansion.
Architectural & Decorative
High-gloss facade panels (mirror-finished 304), structural glass supports, and interior cladding with tight width tolerances for seamless installation.
Energy & Renewables
Solar panel frames (430 for cost-effective corrosion resistance), wind turbine hub components (2507 for offshore durability), and nuclear reactor internals (347 for radiation resistance).
Quality Assurance
Every plate undergoes rigorous testing:
Dimensional Inspection: Laser scanning and caliper measurements to verify thickness, width, and flatness against target tolerances.
Mechanical Testing: Tensile, yield, and impact tests to ensure compliance with grade-specific property requirements.
Corrosion Testing: Salt spray (ASTM B117) and intergranular corrosion (ASTM A262 Practice E) tests for critical environments.
