Product Detail Page: Premium Stainless Steel Weight Plates | 201/304/316L & Super Duplex Grades
Product Overview
Our stainless steel weight plates are engineered for unparalleled durability and precision, crafted from 201/304/316L and super duplex grades (S32750/S32760). These plates meet ASTM, EN, and JIS standards, making them ideal for gym equipment, industrial machinery, and specialized applications like stainless steel induction plates for electromagnetic systems and stainless steel switch plates for electrical enclosures. With customizable thicknesses (2–50mm) and finishes, they combine corrosion resistance, high strength, and aesthetic versatility.

Technical Attributes
Tensile & Bend Strength
- 201 Grade: With a tensile strength of 520 MPa, these plates are cost-effective for stainless steel switch plates in mild environments. Bend strength reaches 780 MPa, suitable for decorative applications.
- 304 Grade: Offers 520 MPa tensile strength and 780 MPa bend strength, ideal for stainless steel induction plates in food processing or medical equipment due to its hygienic 2B/BA finishes.
- 316L Grade: Enhanced by 2–3% molybdenum, it achieves 515 MPa tensile strength and 772.5 MPa bend strength, perfect for marine-grade stainless steel weight plates exposed to chlorides.
- Super Duplex S32750: Delivers 800 MPa tensile strength and 1200 MPa bend strength, designed for extreme environments like offshore oil rigs or chemical reactors.
Weight Calculation
Weight per unit (kg) = Thickness (mm) × Width (m) × Length (m) × Density (g/cm³).
Example: A 304 stainless steel plate (10mm thick, 1m × 1m) weighs 79.3 kg (10 × 1 × 1 × 7.93).
Identification Marking
Each plate is laser-etched with Grade (201/304/316L/S32750), ASTM/EN Standard, Heat Number, and Supplier Code for full traceability.
Why Stainless Steel Rusts? Key Causes & Solutions
Even high-grade stainless steel can corrode under specific conditions:
- Chloride Exposure: Prolonged contact with seawater or de-icing salts causes pitting in 304/201 grades. 316L/S32750 plates resist this due to molybdenum and nitrogen content.
- Mechanical Damage: Scratches from abrasive tools disrupt the chromium oxide layer. Use polished finishes like BA or mirror for stainless steel switch plates to minimize surface damage.
- Galvanic Corrosion: Contact with carbon steel in humid environments accelerates rusting. Isolate stainless steel components with non-conductive materials.
- High-Temperature Oxidation: Temperatures above 800°C deplete chromium. Super Duplex S32750 retains strength up to 300°C.
- Chemical Contamination: Residual acids or alkalis degrade passive films. Clean surfaces with pH-neutral detergents for stainless steel induction plates.
Applications
- Fitness & Gym Equipment: Stainless steel weight plates with high tensile strength for durability in humid gym environments.
- Electromagnetic Systems: Precision stainless steel induction plates for MRI machines or industrial heaters.
- Electrical Enclosures: Corrosion-resistant stainless steel switch plates for outdoor or marine electrical systems.
