Technical Features

Tensile & Bend Strength

Stainless steel rod holders manufactured from grades like 316 and 17-4PH Type 630 exhibit exceptional tensile strength, ranging from 515 MPa to 1,380 MPa, ensuring structural integrity under extreme loads. Bend strength is optimized through precision cold-rolled processing, achieving up to 950 MPa for applications requiring resistance to deformation, such as welding rods for stainless steel frameworks.

Identification Standards

Our products comply with:

ASTM A564 (Precipitation-Hardening Stainless Steel)
ISO 3506 (Mechanical Properties of Corrosion-Resistant Fasteners)
DIN 17440 (European Standards for Stainless Steel)
Each rod holder is laser-marked with grade identification (e.g., 316, 17-4PH) and batch codes for traceability.

Weight Calculation Formula

Calculate weight (kg/m) for stainless steel rod holders:
$Weight = \frac{Diameter ^{2} ( mm ) \times 0.00623}{1 , 000}$
Example: A 6mm diameter rod weighs 0.224 kg/m.

Why Stainless Steel Rusts?

Despite its corrosion resistance, rust in stainless steel can occur due to:

Chloride Exposure: Common in coastal areas or chemical plants, chloride ions penetrate the chromium oxide layer.
Low Chromium Content: Grades like 430 (<12% chromium) lack sufficient corrosion resistance.
Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel) in humid environments.
Mechanical Damage: Scratches or improper welding (e.g., using incompatible welding rods for stainless steel) compromise surface integrity.

Applications

Industrial: Structural supports, machinery components, and welding rods for stainless steel frameworks.
Marine: Corrosion-resistant stainless steel rod holders for shipbuilding and offshore platforms.
Architectural: Custom-sized rods for handrails, curtain systems, and decorative installations.
