Performance Attributes

Tensile & Bending Strength

Our stainless steel round rod bar in AISI 304 delivers tensile strength up to 750 MPa, ideal for structural components requiring both corrosion resistance and load-bearing capacity, such as stainless steel bare welding filler rod in marine or chemical environments. AISI 201 (650–750 MPa) offers a cost-effective alternative for indoor applications like decorative frameworks, while AISI 430 (450–600 MPa) excels in mildly corrosive settings like automotive exhaust systems.

Identification & Traceability

Each stainless steel round rod bar is laser-etched with a unique identifier (e.g., "304-Ø20x6M") that includes grade, diameter, and batch number. This aligns with ASTM/JIS standards and simplifies quality control for projects requiring precision, such as double bar MG9-7 engraved stainless steel rods scribe for tool calibration.

Weight Calculation

Calculate the weight of a stainless steel round rod bar using:
$Weight (kg/m) = \frac{π \times ( Diameter/2 ) ^{2} \times Density}{1000}$

AISI 304/201: Density = 7.93 g/cm³ → A 20 mm rod weighs 2.48 kg/m.
AISI 430: Density = 7.70 g/cm³ → A 20 mm rod weighs 2.41 kg/m.

Why Stainless Steel Can Rust

Despite its corrosion resistance, stainless steel round rod bar may rust under specific conditions:

Chloride Exposure: Prolonged contact with seawater or de-icing salts can degrade the passive chromium oxide layer, particularly in AISI 430 (lower nickel content).
Galvanic Corrosion: Direct contact with carbon steel in humid environments accelerates oxidation. Use insulating materials for stainless steel bare welding filler rod in mixed-metal assemblies.
Surface Contamination: Iron particles from machining tools can embed into stainless steel, causing localized rust. Passivation (nitric acid treatment) restores corrosion resistance.

Manufacturing & Processing

Cold Drawing: Precision cold drawing ensures ±0.05 mm tolerance for double bar MG9-7 engraved stainless steel rods scribe, optimized for CNC machining.
Heat Treatment: AISI 304 undergoes solution annealing (1,050–1,100°C) to eliminate sensitization and enhance intergranular corrosion resistance.
Surface Finishing: Electropolishing (for AISI 304) reduces surface roughness (Ra ≤0.4 μm), minimizing bacterial adhesion in food processing.

Applications

Precision Tooling: Double bar MG9-7 engraved stainless steel rods scribe for measurement instruments and industrial scribers.
Welding & Fabrication: Stainless steel bare welding filler rod (AISI 309L) for joining dissimilar metals like 304L and 439 stainless steels.
Architectural Frameworks: Custom stainless steel round rod bar (AISI 201) for cost-effective indoor railings and decorative structures.
