Description of ASTM 347 Stainless Steel Coils

ASTM 347 Stainless Steel Coils are a high-temperature austenitic stainless steel that has excellent resistance to intergranular corrosion. It is often used in applications where temperatures exceed 800°F (427°C). ASTM 347 Stainless Steel Coils are a common form of this material, and they are manufactured to meet the standards set by ASTM International.

The ASTM 347 Stainless Steel Coils are made using a variety of methods, including hot-rolling, cold-rolling, and annealing. Hot-rolling is the most common method and involves passing a heated slab of steel through a series of rollers to form the desired thickness. Cold-rolling, on the other hand, involves passing the steel through a series of rollers at room temperature, which results in a smoother surface finish. Annealing is a heat treatment process that involves heating the steel to a high temperature and then cooling it slowly to relieve internal stresses and improve its ductility.

ASTM 347 Stainless Steel Coils are used in a variety of applications, including chemical processing, oil and gas refining, and aerospace applications. They are also commonly used in the manufacturing of heat exchangers, boilers, and pressure vessels. In addition, they are often used in high-temperature environments, such as furnaces, ovens, and kilns. ASTM Stainless Steel 347 Coils are equivalent to EN 1.4550 Stainless Steel Coils, X6CrNiNb18-10 Stainless Steel Coils, S34700 Stainless Steel Coils, and X04Cr18Ni10Nb Stainless Steel Coils

ASTM 347 SS Coils have several beneficial properties that make them an attractive material for various applications. One of the primary advantages of this material is its high resistance to intergranular corrosion. This is due to the addition of niobium to the alloy, which helps to stabilize the material and prevent the formation of chromium carbide precipitation along the grain boundaries.

Another important property of ASTM Stainless Steel 347 Coils is their high-temperature strength. This material can withstand temperatures up to 1600°F (871°C) and maintain its strength and ductility, making it an excellent choice for high-temperature applications. Additionally, ASTM 347 stainless steel has good weldability, which makes it easy to join together with other materials.

ASTM 347 SS Coils are also highly resistant to oxidation and scaling at high temperatures. This property makes them suitable for use in environments where exposure to high temperatures and corrosive gases is common, such as in petrochemical and power generation industries. Moreover, this material also has good formability and can be easily fabricated into various shapes and sizes.

To ensure that ASTM SS 347 Coils meet the required specifications, they must undergo rigorous testing and inspection procedures. These tests include chemical composition analysis, mechanical testing, and non-destructive testing, among others. Additionally, the coils must be certified to comply with the ASTM International standards.

In summary, ASTM 347 Stainless Steel Coils are a highly durable and corrosion-resistant material that can withstand high temperatures and harsh environments. Their excellent properties, including high-temperature strength, weldability, and formability, make them an ideal material for various applications in industries such as chemical processing, power generation, and aerospace.

When it comes to the manufacturing process of ASTM 347 Stainless Steel Coils, the selection of raw materials and the production process plays a crucial role in ensuring the material's quality and performance. The starting material used in the production of ASTM 347 Stainless Steel Coils is typically a high-quality stainless steel scrap that meets the required chemical composition and purity standards.

After the raw material selection, the manufacturing process starts with melting the steel in an electric arc furnace or a vacuum induction furnace. The melted steel is then poured into a continuous casting machine, where it is solidified into a semi-finished product called a billet. The billet is then hot-rolled into a thin strip of steel that is further processed into ASTM 347 Stainless Steel Coils.

During the rolling process, the steel undergoes various treatments, such as annealing and pickling, to improve its properties and surface finish. Annealing is a heat treatment process that involves heating the steel to a high temperature and then slowly cooling it to relieve internal stresses and improve its ductility. Pickling is a chemical process that removes any surface impurities, such as oxides and rust, from the steel.

The final step in the manufacturing process of ASTM Stainless Steel 347 Coils is the inspection and testing of the finished product. This ensures that the coils meet the required specifications for chemical composition, mechanical properties, and surface finish. ASTM International sets the standards for the testing and inspection procedures of stainless steel coils, which include chemical composition analysis, mechanical testing, non-destructive testing, and surface finish inspection.

ASTM SS 347 is a stabilized austenitic stainless steel that contains niobium, which enhances its corrosion resistance and high-temperature strength. Niobium forms carbides with carbon, which prevents the formation of chromium carbide and protects the grain boundaries from intergranular corrosion. The addition of niobium also improves the steel's resistance to pitting and crevice corrosion.

ASTM 347 Stainless Steel Coils also have excellent weldability, which makes them easy to join together with other materials. This property is particularly useful in applications such as piping systems, where the coils need to be welded to other components to form a complete system.

Another important property of ASTM 347 Stainless Steel Coils is their formability. This material can be easily formed into various shapes and sizes using standard forming techniques such as bending, stamping, and deep drawing. This makes it suitable for use in a range of applications, including automotive parts, kitchen appliances, and architectural components.

In summary, ASTM SS 347 Coils are a versatile and durable material with excellent properties, including high-temperature strength, corrosion resistance, weldability, and formability. The manufacturing process involves careful selection of raw materials, strict quality control procedures, and a range of treatments to improve the steel's properties and surface finish.
