Velocity Steel India is a trustworthy supplier with an extensive variety of stainless steel grades and nickel high alloys. Owing to their comprehensive product range of sheets, plates, coils, round bars, square bars, wires, welded and seamless tubes, and washers, bolts, nuts and special pieces in the form of fasteners, they are the preferred supplier for numerous industrial applications.
The characteristic of SS321 is the addition of titanium, forming stable titanium carbides that combine with carbon rather than chromium, thus ensuring corrosion resistance over a long period even at high temperatures. Consequently, SS321 is particularly suitable for high-temperature service, particularly for continuous service in the 800 to 1600°F (427 to 870°C) range.
Applications needing high-temperature strength and corrosion and oxidation resistance frequently use stainless steel SS321. Because titanium stabilizes the substance, it can be utilized in ways that other stainless steels cannot. Here are some typical uses for SS321:
| Grade | C | Mn | Si | P | S | Cr | Mo | Ni | N | Other | |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 321 | min. | - | 2 | 0.75 | 0.045 | 0.03 | 17 | - | 9 | 0.1 | Ti=5(C+N) |
| max | 0.08 | 19 | 12 | 0.7 |
Stainless Steel SS321 is one of the strongest and most versatile of the alloys, renowned for its excellent oxidation resistance at high temperatures, intergranular corrosion, and overall high-temperature strength. Titanium addition stabilizes the alloy, and this stops the precipitation of chromium carbide and offers better performance where other stainless steel will degrade.
SS321, with its unique properties, is used in many industries including aerospace, chemical processing, power generation, and petrochemicals, where the components are subjected to corrosive atmospheres and high temperatures. It is particularly well suited to sensitive applications such as exhaust systems, heat exchangers, gas turbines, and chemical reactors, due to its capability to remain strong and oxidation resistant.
