Technical Features

Tensile & Bend Strength

Stainless steel welding rods exhibit exceptional tensile strength, with grades like 316L and ER309LMo achieving up to 1,380 MPa, ensuring reliable performance in structural and high-stress applications. Bend strength is optimized through advanced cold-rolled processing, reaching 950 MPa for critical uses such as stainless steel earth rods in grounding systems.

Identification Standards

Our rods comply with global certifications:

AWS A5.9/A5.22 (TIG and MIG Welding Standards)
ISO 14343 (Stainless Steel Filler Metals)
ASME SFA-5.9 (Chemical Composition Requirements).
Each rod is laser-etched with grade markings (e.g., 316L, 309L) and batch codes for traceability.

Weight Calculation Formula

Calculate weight (kg/m) for stainless steel welding rods:
$Weight = \frac{Diameter ^{2} ( mm ) \times 0.00623}{1 , 000}$
Example: A 3.2mm diameter rod weighs 0.063 kg/m.

Why Stainless Steel Rusts?

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

Chloride Exposure: Coastal or chemical environments degrade the chromium oxide layer, especially in grades with <12% chromium (e.g., 430).
Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel) in humid conditions.
Mechanical Damage: Scratches or improper welding techniques (e.g., using incompatible tig welding stainless steel filler rod).
Low Chromium Content: Grades like 201 lack sufficient corrosion resistance for harsh applications.

Applications

Industrial Welding: Structural frameworks, stainless steel earth rods, and machinery components.
Marine & Chemical: Corrosion-resistant tig welding stainless steel filler rod for pipelines and offshore platforms.
Construction: Custom rods for architectural supports, handrails, and sanitary systems.
