321 Stainless steel Sheet description

A 321 stainless steel sheet is an austenitic stainless steel alloy that offers excellent high-temperature strength, good corrosion resistance, and enhanced resistance to intergranular corrosion. Here is a description of a 321 stainless steel sheet:

1. Composition: 321 stainless steel primarily consists of iron, chromium (17-19%), nickel (9-12%), and a small amount of titanium (0.6-0.75%). The addition of titanium stabilizes the alloy against sensitization and prevents the formation of chromium carbide precipitation at high temperatures.

2. High-temperature strength: One of the key advantages of 321 stainless steel is its exceptional strength and structural stability at elevated temperatures. It retains its mechanical properties and resistance to creep and oxidation even in high-temperature applications, typically up to 900-1500°C (1652-2732°F). This makes it suitable for use in heat exchangers, furnace parts, and other high-temperature environments.

3. Corrosion resistance: 321 stainless steel offers good general corrosion resistance in a wide range of environments. It is highly resistant to corrosion from atmospheric conditions, fresh water, and many organic and inorganic chemicals. The addition of titanium provides improved resistance to intergranular corrosion, making it suitable for applications where exposure to high temperatures or sensitizing environments is a concern.

4. Weldability: 321 stainless steel is easily weldable using common welding methods, including TIG (tungsten inert gas) and MIG (metal inert gas) welding techniques. It exhibits good weldability and can be readily fabricated without post-weld annealing, reducing the risk of sensitization and intergranular corrosion.

5. Applications: 321 stainless steel sheets find applications in various industries and applications, including:

   • Aerospace and aviation components
   • Heat exchangers and furnace parts
   • Exhaust systems
   • Chemical processing equipment
   • Food processing and storage equipment
   • Pharmaceutical equipment
   • Automotive components
   • Architectural and decorative applications

6. Availability: 321 stainless steel sheets are available in various thicknesses, widths, and lengths. They can be supplied with different surface finishes, including mill finish, brushed finish, or polished finish.

Please note that the specific properties, availability, and standards for 321 stainless steel sheets may vary depending on the supplier and the specific manufacturing process. It is advisable to consult with the supplier or review the relevant specifications to ensure the desired properties and specifications are met for your specific application.

Unique properties of 317L stainless steel

321 stainless steel is a popular material that possesses unique and impressive properties. One of its most notable features is its exceptional corrosion resistance, which makes it resistant to rust and other forms of deterioration caused by environmental factors. It is also highly resistant to heat and oxidation, making it suitable for use in high-temperature environments.

Additionally, 321 stainless steel has excellent machinability properties, allowing it to be easily shaped into various forms without losing its structural strength. Its superior toughness and ductility make it an ideal choice for manufacturing equipment that requires durability and reliability.

Another characteristic of 321 stainless steel is its low magnetic permeability, which makes it useful in applications where magnetic interference must be avoided. This property enables the material to resist magnetization when subjected to intense electromagnetic fields or radiation.

Due to its cost-effectiveness compared with other types of alloys used in similar applications, 321 stainless steel offers manufacturers significant savings while providing desirable mechanical properties.

These unique properties make 321 stainless steel an attractive option for various industrial applications such as automotive parts manufacturing, kitchen equipment production, construction materials fabrication among others.

What shapes can 321 stainless steel be made into?

321 stainless steel can be formed into different grades of stainless steel plate using various methods. The most common method is to use a press brake with appropriate dies to form the desired shape. Other methods include using dies, stamping or hydroforming.

321 stainless steel stainless steel sheet can be made into many different shapes,

We can make a suitable shape according to your needs.

Why choose 321 stainless steel?

When it comes to selecting the right material for your project, there are a plethora of options available. However, 321 stainless steel has become an increasingly popular choice amongst many industries in recent years. Here’s why.

Its excellent corrosion resistance properties make it suitable for use in harsh environments such as marine and chemical applications. This is due to the addition of manganese which enhances its overall performance.

Secondly, 321 stainless steel exhibits exceptional wear and tear resistance making it ideal for products that require high durability such as kitchen appliances and automotive parts.

This type of steel has good heat resistance properties and can withstand temperatures up to 870°C without losing strength or becoming brittle.

Fourthly, unlike other types of stainless steel that contain nickel which can cause allergic reactions in some people, 321 stainless steel is nickel-free making it a safer option for those with sensitive skin.

Compared to other grades of stainless steel like 310S or 321, 321 stainless steel is more cost-effective while still providing similar benefits making it an attractive option from both economic and performance perspectives.

Surface Finish

Stainless steel not only has corrosion resistance, but also has the advantages of heat resistance, processability, strength, appearance and so on. Stainless steel manufacturers take advantage of the properties of stainless steel to improve quality through various surface treatments. Jin Ruiheng Stainless Steel offers BA, 2B, 2D, 2K, 4K, 6K, 8K, NO.4, HL, SB, Embossed and other different types of stainless steel surface treatment processes.
