EN 10204-3.1 Certificated 321F Stainless Steel Grinding Bar / Stainless Steel Rod in 6m Length

Introduction to EN 10204-3.1 Certificated 321F Stainless Steel Grinding Bar / Stainless Steel Rod

The EN 10204-3.1 Certificated 321F Stainless Steel Grinding Bar is a high-performance material designed for applications that require high resistance to oxidation, intergranular corrosion, and mechanical stress. The 321F grade is a titanium-stabilized version of stainless steel, primarily used in environments exposed to elevated temperatures and corrosive substances. Manufactured in 6-meter lengths, this stainless steel rod is precision ground to achieve superior surface finishes and dimensional accuracy, making it ideal for high-precision machining applications.

This EN 10204-3.1 certification guarantees that the material complies with the strictest standards of quality control, offering end-users a certified verification of the chemical composition, mechanical properties, and testing conducted during production. Such certification is essential for industries that require traceability and reliability in their materials, such as aerospace, petrochemical, and power generation.

In this product description, we will explore the key features, specifications, applications, and benefits of EN 10204-3.1 Certificated 321F Stainless Steel Grinding Bars and rods in 6-meter lengths.

Key Features of EN 10204-3.1 Certificated 321F Stainless Steel Grinding Bar

  1. Titanium Stabilization: The titanium content in the 321F stainless steel enhances the material's resistance to sensitization and intergranular corrosion, which occurs at elevated temperatures, particularly during welding.

  2. EN 10204-3.1 Certification: This certificate ensures that the material has been tested and meets the required standards, with an official report confirming the chemical and mechanical properties.

  3. Precision Grinding: The rods are precision ground to ensure minimal dimensional tolerance, providing smooth, accurate surfaces and consistent diameter for demanding applications.

  4. 6-Meter Length: The bars come in a standard length of 6 meters, which can be easily cut into shorter lengths to meet specific requirements, ensuring versatility in manufacturing processes.

Chemical Composition of 321F Stainless Steel

The 321F stainless steel alloy is specially designed for use in high-temperature applications, offering excellent resistance to oxidation and corrosion. Below is the typical chemical composition of 321F stainless steel:

Element Content
Chromium (Cr) 17.0 - 19.0%
Nickel (Ni) 9.0 - 12.0%
Titanium (Ti) 5xC min.
Manganese (Mn) 2.0% max.
Silicon (Si) 1.0% max.
Carbon (C) 0.08% max.
Phosphorus (P) 0.045% max.
Sulfur (S) 0.030% max.

The addition of titanium (Ti) to the composition stabilizes the material and prevents the formation of chromium carbide precipitates during welding, which could lead to intergranular corrosion. This gives 321F stainless steel superior performance in high-temperature and welded applications, making it ideal for industries requiring such material qualities.

Mechanical Properties of 321F Stainless Steel

321F stainless steel offers excellent mechanical properties, making it ideal for use in high-stress and high-temperature environments. The material’s strength, ductility, and toughness are key factors in its suitability for demanding industrial applications.

Property Value
Tensile Strength 515 - 690 MPa (75,000 – 100,000 psi)
Yield Strength 205 - 350 MPa (30,000 – 50,000 psi)
Elongation 40% min (in 50 mm)
Hardness Rockwell B (HRB) 90 max
Modulus of Elasticity 200 GPa (29 x 10³ ksi)

These properties ensure that 321F stainless steel rods provide high mechanical performance under both static and dynamic loading conditions. The material can be subjected to high tensile and yield strength demands, as well as harsh environmental conditions, while maintaining its structural integrity.

Thermal and Corrosion Resistance of 321F Stainless Steel

321F stainless steel is specifically formulated to resist oxidation and other forms of corrosion, especially in high-temperature environments. The material’s resistance to corrosion and oxidation is a key feature that makes it ideal for use in applications that involve contact with high-temperature gases, acids, or aggressive chemicals.

Property Value
Maximum Service Temperature 870°C (1600°F)
Thermal Conductivity 15.1 W/m·K at 100°C
Specific Heat Capacity 500 J/kg·K at 25°C
Coefficient of Thermal Expansion 17.3 µm/m·K at 20–100°C

The alloy’s ability to withstand oxidation at high temperatures (up to 870°C) makes it ideal for use in industries such as aerospace, power generation, and petrochemical processing, where components are exposed to high heat or corrosive substances.

EN 10204-3.1 Certification for Traceability

The EN 10204-3.1 certificate provides traceability and assurance of quality, ensuring that each batch of 321F stainless steel bars has undergone thorough testing and inspection. The certification provides the following:

  1. Chemical Composition Report: Ensures that the material meets the specific chemical requirements for Alloy 321F.

  2. Mechanical Properties Report: Confirms that the material exhibits the expected mechanical strength, yield strength, and elongation values.

  3. Testing and Inspection: Includes reports from authorized third-party testing bodies confirming the material’s conformity with the relevant EN standards.

This certificate is often required by industries where quality control, compliance, and traceability are critical for the manufacturing process.
