Corrosion Resistance
- The stainless steel rod rack utilizes 201/303-grade alloys with 16-18% chromium and 1% nickel, offering balanced resistance to mild acids, alkalis, and atmospheric corrosion.
- Ideal for storing welding rods for stainless steel in humid environments (e.g., marine workshops).
Cold-Drawn Precision
- Cold drawing reduces surface roughness (Ra ≤0.8μm) and enhances dimensional accuracy (±0.1mm), ensuring seamless compatibility with stainless steel closet rod systems.
Modular Design
- Interlocking grooves and bolt-free assembly enable rapid reconfiguration for diverse applications (e.g., vertical storage for stainless steel closet rod or horizontal racks for welding rods).

Tensile Strength (620 MPa) exceeds standard 201-grade bars (520 MPa) due to cold work hardening during drawing.
Bend Strength (320 MPa) allows the rack to withstand repeated loading without permanent deformation, critical for heavy welding rods for stainless steel storage.

Formula: Weight (kg/m) = (Diameter² × Density) / 162
- Density of 201/303: 7.8 g/cm³
- Example: 20mm rod = (20² × 7.8) / 162 ≈ 19.2 kg/m

Laser-etched grade labels (e.g., "303") and QR codes for traceability (compliant with ASTM A484).

While the stainless steel rod rack resists rust, improper use can lead to localized corrosion:

Chloride Exposure: Coastal environments accelerate pitting; periodic cleaning with pH-neutral detergents is recommended.
Mechanical Scratches: Surface damage disrupts the passive chromium oxide layer, necessitating passivation for racks storing abrasive welding rods for stainless steel.
Galvanic Corrosion: Avoid direct contact with carbon steel components.

Cold Drawing: Bars are drawn through tungsten carbide dies at room temperature to achieve precise dimensions and surface polish.
Solution Annealing: Heated to 1010-1120°C and water-quenched to relieve stresses and restore ductility.
Surface Treatment: Electrolytic polishing for bright finish or bead blasting for matte textures.

Welding Workshops: Organize welding rods for stainless steel (10mm/20mm) with labeled slots to reduce material waste.
Industrial Closets: Customizable stainless steel closet rod systems for heavy tool storage.
Automotive Assembly: Corrosion-resistant racks for exhaust components and fasteners.

Superior Durability
- Cold-drawn 201/303 alloys offer 30% higher fatigue life compared to hot-rolled alternatives.
Customization
