1. Introduction
The 434 stainless steel tape is a ferritic stainless steel product, characterized by its good corrosion resistance, formability, and magnetic properties. With the addition of molybdenum, it offers enhanced performance compared to many other ferritic stainless steels, making it a popular choice for various industrial and consumer applications.
2. Key Properties
2.1 Corrosion Resistance
- General Corrosion: 434 stainless steel tape demonstrates excellent resistance to atmospheric corrosion, making it suitable for outdoor applications. It can withstand exposure to mild chemicals and moisture without significant degradation.
- Pitting and Crevice Corrosion: The inclusion of molybdenum improves its resistance to pitting and crevice corrosion, especially in chloride - containing environments. This makes it a reliable option for applications where such types of corrosion are a concern.
2.2 Mechanical Properties
- Tensile Strength: Typically ranges from 520 - 725 MPa (75,420 - 105,140 psi), providing good strength for structural and functional applications.
- Yield Strength: Around 205 - 275 MPa (29,730 - 39,880 psi) in the annealed condition, offering a balance between strength and formability.
- Elongation: Shows good ductility with an elongation of ≥20% in the annealed state, allowing for various bending, rolling, and shaping operations during manufacturing processes.
2.3 Chemical Composition
3. Fabrication and Formability
434 stainless steel tape can be easily processed using common metalworking techniques. It can be cut to specific widths and lengths with high precision, and formed into various shapes through processes like stamping, rolling, and coiling. The material responds well to cold working, allowing manufacturers to achieve the desired mechanical properties and dimensional accuracy. Welding is also possible, although proper precautions should be taken to avoid issues such as cracking and loss of corrosion resistance. Suitable welding methods include TIG and MIG welding with appropriate filler materials.
4. Applications
- Automotive Industry: Used for automotive trim, exhaust systems, and fuel tanks due to its corrosion resistance and formability. It can withstand the harsh conditions of the automotive environment, including exposure to road salts, moisture, and temperature variations.
- Appliance Manufacturing: Ideal for components in household appliances such as refrigerators, ovens, and washing machines. Its attractive appearance and corrosion - resistant properties make it suitable for both visible and internal parts.
- Architectural Applications: Employed for decorative trims, handrails, and building facades, especially in areas with moderate exposure to the elements. Its magnetic nature can also be utilized in certain architectural designs and installations.
- Electronics Industry: Used in the production of electronic enclosures and components, where its corrosion resistance and formability are valuable properties. It can protect internal electronics from environmental damage while being easily shaped to fit specific design requirements.
5. Surface Finishes
Available in a variety of surface finishes:
- Mill Finish: The as - rolled surface, which is smooth but has a dull appearance. It is often used as a base for further processing or in applications where the surface finish is not a critical factor.
- Bright Annealed Finish: Achieved by annealing the tape in a controlled atmosphere, resulting in a smooth, bright, and clean surface. This finish is commonly used in applications where aesthetics are important, such as in decorative trims and appliance components.
- Polished Finish: A highly reflective surface obtained through mechanical polishing. It is suitable for high - end decorative applications and where a more refined appearance is desired.
6. Standards and Certifications
434 stainless steel tape complies with international standards such as ASTM A240, EN 10088 - 2, and JIS G4305. These certifications ensure that the product meets strict quality and performance requirements, providing customers with confidence in its reliability and consistency.
7. Maintenance
Requires minimal maintenance. Regular cleaning with a soft cloth and mild detergent can remove surface dirt and stains, maintaining its appearance and corrosion - resistant properties. Avoid using abrasive cleaners or sharp tools that may scratch the surface, as scratches can potentially reduce its corrosion resistance over time.
8. Packaging and Delivery
The 434 stainless steel tape is carefully packaged to prevent damage during transportation. It is typically wound onto sturdy cores and wrapped in protective materials such as plastic films or paper. For large orders, additional packaging in wooden crates or metal containers can be provided. Delivery services are available worldwide, with options for express shipping or customized delivery schedules to meet customer needs.
