Detailed Technical Insights
Tensile & Bending Strength
Stainless steel square bar rod excels in both tensile and bending strength, making it ideal for load-bearing structures. Grade 304, with a tensile strength of ≥520 MPa, is widely used in industrial frameworks where resistance to deformation is critical. Its high ductility (≥40% elongation) allows for cold bending and welding without cracking.
For variety stainless steel round rods bar for DIY craft, Grade 201 offers a balance of affordability and strength (≥520 MPa tensile strength), suitable for decorative projects like garden sculptures or custom furniture. Grade 316, enhanced with 2–3% molybdenum, maintains structural integrity even in chloride-rich environments like coastal areas.
Weight Calculation
Use the formula to estimate the weight of stainless steel round bar steel rod:
For a round rod:
Example: A 10mm diameter × 1m rod weighs 0.63 kg (density = 7.93 g/cm³).
Identification & Marking
- Laser Etching: Permanent markings include ASTM grade (e.g., "304"), manufacturer code, and batch number.
- Color Coding: Red for 201, blue for 304, and yellow for 316 to simplify inventory management.
Why Stainless Steel Rusts
While stainless steel is corrosion-resistant, rust can occur under specific conditions:
- Chloride Exposure: Coastal or industrial environments degrade the passive chromium oxide layer. Grade 316 mitigates this risk due to its molybdenum content.
- Mechanical Damage: Scratches during fabrication expose raw steel. Always use nylon tools and protective films during handling.
- Galvanic Corrosion: Contact with carbon steel or aluminum in moist environments. Insulate metals with dielectric barriers.
- Low Chromium Content: Grade 201 (16% Cr) is less resistant than Grade 304 (18% Cr).
