Austenitic Stainless Seamless Steel Tubing 6mm ASMT 301 For Handrail Rolling
ASTM A301 is not a recognized standard for stainless steel pipes. The ASTM A301 specification does not exist, and there is no specific ASTM standard dedicated to stainless steel pipes labeled as ASTM 301.
However, there is a widely used stainless steel grade known as AISI 301, which is governed by the American Iron and Steel Institute (AISI) and not ASTM. AISI 301 is an austenitic stainless steel that offers good corrosion resistance, high strength, and excellent formability. It is commonly used in various applications, including stainless steel pipes.
Here is a description of AISI 301 stainless steel pipes:
Austenitic stainless steel: AISI 301 is an austenitic stainless steel grade that belongs to the 300 series stainless steels. Austenitic stainless steels are known for their excellent corrosion resistance, high ductility, and good mechanical properties.
Corrosion resistance: AISI 301 stainless steel pipes provide good corrosion resistance in mild environments. They offer resistance to atmospheric corrosion, general food processing environments, and mildly corrosive chemicals. However, they may not exhibit the same level of corrosion resistance as more corrosion-resistant stainless steel grades like 304 or 316.
High strength: AISI 301 stainless steel pipes have high tensile strength and yield strength compared to many other stainless steel grades. This high strength makes them suitable for applications that require structural integrity and load-bearing capabilities.
Formability: AISI 301 stainless steel pipes exhibit good formability, allowing for easy fabrication, bending, and forming operations. They can be readily shaped into various configurations, making them suitable for applications that require complex shapes or precise manufacturing.
Applications: AISI 301 stainless steel pipes are used in a wide range of applications, including automotive components, chemical processing equipment, food processing equipment, springs, fasteners, and architectural structures. They are suitable for both structural and decorative purposes.
When considering AISI 301 stainless steel pipes for a specific application, it is important to evaluate the environmental conditions, corrosion resistance requirements, and mechanical properties needed to ensure the suitability and optimal performance of the pipes.
According to different uses, the requirements for various properties of stainless steel pipes are different, such as acid and alkali corrosion resistance, intergranular corrosion resistance and stress corrosion cracking performance, pitting resistance, climate corrosion resistance, high temperature and oxidation resistance. For use in high temperature environment, it is also required to have satisfactory high temperature persistent strength, durable plasticity, creep resistance and aging stability.
Stainless steel pipe is mainly used for auxiliary exchanger pipe, water heater pipe, main pipe, cooling water pipe and other pipes. Electricity, as the basis of national economic development, national economy and people's livelihood. The inner wall of the stainless steel pipe is smooth, the water transmission resistance is small, can withstand the erosion of high water flow rate, after solution treatment, the mechanical properties of the pipe and the matrix, the corrosion resistance is basically the same, the performance is excellent, and it is widely used in heaters, boilers, heat exchangers, condensers.
China's production of seamless stainless steel pipes is mainly concentrated in Inner Mongolia Baotou Steel, Shanghai Five Steel (Group) Co., LTD., Great Wall Special Steel Co., LTD., Dalian Steel Plant, Fushun Steel Plant, Daye Special Steel Co., LTD., Chengdu Seamless Steel Plant, although the specific process equipment of each production facility is different. However, its production process is mainly divided into hot-rolled seamless stainless steel pipe production process, cold-working seamless stainless steel pipe production process and hot-extruded seamless stainless steel pipe production process.
