321 Stainless Sheet

321 stainless steel sheet is a type of high-quality stainless steel sheet that is widely used in many industries. It has excellent corrosion resistance, high strength, and good heat resistance. The addition of titanium in its chemical composition enhances its overall performance, which makes it ideal for applications where extreme temperatures and corrosive environments are factors.

One of the advantages of 321 stainless steel sheet is its ability to withstand extreme temperatures. This makes it a popular choice for use in high-temperature applications such as aerospace components, heat exchangers, and exhaust systems. Additionally, it has excellent weldability and can be easily fabricated, making it a cost-effective material for many industrial applications.

Another benefit of 321 stainless steel sheet is its resistance to corrosion. It is highly resistant to intergranular corrosion and is less susceptible to stress corrosion cracking than many other grades of stainless steel. This makes it a preferred material for use in harsh environments such as chemical processing plants, paper mills, and offshore oil and gas production facilities.

Specifications

• Chemical composition: 321 stainless sheet has a minimum of 17% chromium and 9% nickel, making it very durable and resistant to corrosion.
• Heat-resistant: This material can withstand temperatures up to 930°C (1700°F) without losing its strength or durability.
• Weldability: excellent welding capabilities and is easy to join with other materials.
• Formability: It can be easily formed into complex shapes and structures, making it ideal for a range of applications.
• Strength: can withstand heavy loads without deformation.

Characteristics

• Good corrosion resistance.  is known for its excellent corrosion resistance in the industry. It can work at extreme high temperatures for a long time without loss of performance, and is very suitable for parts and materials production in high temperature and high pH working environments.
• Excellent antioxidant properties. Due to the addition of titanium, the oxidation resistance of 321 stainless steel plate is very good, and the stability of the material can be maintained under high temperature and pressure.
• Remarkable processing performance.  economical and practical and has outstanding processing performance. Compared with 304 stainless steel plate, its weldability and processability are better, which can meet the processing needs of different industries.
• Good mechanical properties. good mechanical properties at high temperature, high temperature hardness can still remain stable, has a very good tensile strength and compressive strength.
• Wide range of application. widely used in aerospace, chemical, petroleum, electricity, food and other fields. Not only that, it is also widely used in ordinary life fields such as restaurants, families, and kitchens, and its multi-field application scope also shows its excellent performance.

Productive Process

• Raw material selection: high-quality stainless steel material is the basis to ensure the quality of 321 stainless steel plate. In the production process, the selection of high-quality 316L stainless steel as raw materials.
• Processing: Through multiple processing processes, including cold drawing, pickling, passivation, etc., the surface of 321 stainless steel plate is smoother and smoother, while improving its corrosion resistance.
• Heat treatment: Solution treatment and aging treatment at high temperatures are essential steps for the production of high-quality 321 stainless steel plates. These steps can improve the properties of the steel and increase the toughness and strength of the material.
• Surface treatment: In order to prevent oxidative rust, the surface of 321 stainless steel plate needs to be polished and sandblasted during the production process, and coated with a protective film to maintain its good surface finish.
• Strict quality inspection: In the production process of stainless steel plate, it is necessary to carry out a variety of strict inspection work, such as chemical composition analysis, mechanical properties testing, surface finish testing, etc., to ensure that the production of stainless steel plate has excellent quality characteristics.
