SS 321 Plates
SS 321 Plates
Renam Alloys Inc. – Leading Manufacturer and Supplier of SS 321 Plates
Renam Alloys Inc. is a globally recognized manufacturer, exporter, and supplier of high-quality SS 321 plates. These plates are offered in various sizes, thicknesses, and types (including seamless, welded, and fabricated) to meet diverse customer requirements. Custom-made specifications are also available on request, along with competitive pricing and excellent after-sales services.
SS 321 is a highly durable and resistant alloy, widely used for applications in high-temperature environments due to its outstanding resistance to oxidation and corrosion.
Overview of SS 321 Alloy
Stainless Steel 321 is an austenitic, non-magnetic stainless steel that is stabilized with titanium. The titanium helps to prevent the formation of chromium carbide, which can occur in high-temperature applications and lead to intergranular corrosion. SS 321 is known for its excellent resistance to oxidation and corrosion in high-temperature environments (up to 900°C) and is ideal for applications where high strength and resistance to oxidation are critical.
This alloy also exhibits excellent weldability, making it an ideal material for structural applications in harsh environments.
Salient Features of SS 321 Plates
- Excellent High-Temperature Resistance: SS 321 offers outstanding resistance to oxidation and corrosion, even at high temperatures.
- Enhanced Strength: The alloy provides high tensile strength and is capable of withstanding high-stress applications.
- Corrosion Resistance: SS 321 is resistant to both general corrosion and localized corrosion, including pitting and crevice corrosion.
- Weldability: SS 321 has excellent weldability and can be welded using conventional welding techniques.
- Non-Magnetic Properties: The alloy maintains its non-magnetic properties even after being exposed to elevated temperatures.
- Durability and Longevity: SS 321 is highly durable and can withstand demanding environments for extended periods.
Manufacturing of SS 321 Plates
At Renam Alloys Inc., SS 321 plates are fabricated using high-quality raw materials sourced from reliable market vendors. Before manufacturing, all materials are thoroughly tested for purity and quality assurance. The plates are produced using advanced technology and modern machinery, ensuring that the end product meets both national and international quality standards.
The production process is carefully supervised by a team of skilled professionals to maintain the highest quality standards throughout. This ensures that the final product is durable, reliable, and suitable for a wide range of applications.
Testing of SS 321 Plates
Renam Alloys Inc. conducts rigorous testing during the manufacturing process to ensure that every batch of SS 321 plates meets the highest standards of quality. Some of the tests performed include:
- Positive Material Identification Test
- Mechanical Test
- Hardness Test
- Intergranular Corrosion Test
- Pitting Resistance Test
- Flattening Test
- Flaring Test
- Chemical Composition Test
Mill Test Certificates (MTC) are provided in accordance with EN 10204/3.1B, along with third-party inspection reports, radiography test reports, and raw material certificates.
Packaging and Shipping
To ensure that SS 321 plates reach their destination without damage, Renam Alloys Inc. uses high-quality packaging methods. The plates are wrapped in poly bags and securely packed in wooden cases, crates, or pallets that are free from fumigation and impurities.
All necessary shipping documents, including a packaging list, commercial invoice, raw material test report, and guarantee letter, are provided with each order. Fast and reliable shipping is guaranteed, ensuring timely delivery to global customers.
