Key Features

1. Tensile & Bend Strength

Our stainless steel rod bar excels in mechanical performance. The tensile strength of SUS304 (520 MPa) ensures resistance to deformation under heavy loads, while its yield strength (205 MPa) guarantees structural integrity in dynamic environments. For bend strength, the formula $σ_{b} = \frac{M \cdot y}{I}$ applies, where $M$ is bending moment, $y$ is distance from the neutral axis, and $I$ is the moment of inertia. Our bars are tested to withstand bending angles up to 180° without cracking, making them ideal for architectural frameworks and machinery components.

2. Corrosion Resistance

The chromium-nickel alloy in SUS304 forms a passive oxide layer, preventing oxidation. However, stainless steel rust can occur due to:

Chloride exposure (e.g., coastal environments).
Mechanical damage (scratches or abrasions).
Contaminants (organic acids, salts).
Our china stainless steel rod bar uses 304L (low carbon) for enhanced weldability and reduced sensitization in corrosive settings.

3. Weight Calculation

Weight per meter (kg/m) for stainless steel round rod bar:
$Weight = \frac{π \times D ^{2}}{4} \times 7.93 (density in g/cm^{3}) \times 0.001$
For flat bars:
$Weight = Width \times Thickness \times 7.93 \times 0.001$

4. Identification & Marking

Bars are laser-marked with:

Grade (e.g., SUS304, 316L).
Batch number.
Standard compliance (ASTM, JIS, EN).
Certifications include Mill Test Reports (MTRs) and ISO 9001 compliance.
