Key Properties & Manufacturing Process
Our stainless steel rods are forged using advanced vacuum arc remelting (VAR) technology, followed by controlled heat treatments (quenching, tempering, and precipitation hardening) to enhance mechanical strength and thermal stability. Key attributes include:
- Tensile Strength:
- 304/316: 515–860 MPa (up to 1,200 MPa cold-worked).
- 310: 600–950 MPa (ideal for furnace components and exhaust systems).
- 17-4 PH: 1,100–1,400 MPa (heat-treated for aerospace and defense).
- Bending Strength: Resists deformation under load, with yield strengths ranging from 210 MPa (annealed 304) to 1,050 MPa (cold-drawn 316).
Identification & Marking
Each hexagonal rod stainless steel is traceable via laser-etched identifiers:
- AISI/SAE Codes: Grade labels (e.g., 316L, 310S).
- ISO Standards: Chemical composition markings (e.g., X5CrNi18-10 for 304).
- Batch Numbers: Compliant with ASTM A276 (bars) and ASME SB479 (welding rods).
Weight Calculation
Calculate the weight of a 3/8 stainless steel rod or hexagonal bars using the formula:
Example: A 3/8" (9.5mm) diameter, 6m-long 316 rod weighs 3.36 kg.
Why Does Stainless Steel Rust?
Although stainless steel is corrosion-resistant, specific conditions can compromise its integrity:
- Chloride Exposure: Saltwater or industrial chemicals degrade the chromium oxide layer.
- Low Chromium Content: Grades with <10.5% Cr (e.g., 430) lack sufficient passivation.
- Galvanic Corrosion: Contact with carbon steel or aluminum accelerates oxidation.
- Thermal Stress: Prolonged exposure above 800°C causes scaling and embrittlement.
- Surface Contamination: Iron particles from tools induce localized pitting.
To mitigate rust, use nitric acid passivation or electropolishing to restore the protective oxide layer.
Applications
- Hexagonal Rod Stainless Steel: Structural fasteners, valve stems, and marine hardware due to high torque resistance.
- Welding Solutions: what rod is used to weld stainless steel to metal? Use 309L or 312 stainless steel welding rods for dissimilar metal joints (e.g., stainless to carbon steel).
- High-Temperature Systems: Heat exchangers, furnace trays, and automotive exhaust components (310 grade).
