Our distinguished stainless steel pipe is an exceptionally adaptable hollow cylindrical steel, serving a myriad of industries. Its applications span from the robust world of petroleum and the innovative realm of chemicals to the precise fields of medicine and food production. Also embraced by the light industry and mechanical instrumentation sectors, it is celebrated for its remarkable strength in both bending and torsion, while maintaining a feather-light feel. This makes it impeccably perfect for crafting mechanical parts and engineering structures, and lends an elegant touch to furniture and kitchenware.
By examining its composition, this versatile material can be categorized into a variety of series: the Cr series (400 series), known for its durable qualities; the Cr-Ni series (300 series), offering enhanced properties; the Cr-Mn-Ni series (200 series), providing a unique blend of elements; the heat-resistant chromium alloy steel (500 series), designed for high-temperature applications; and the advanced precipitation hardening series (600 series), crafted for superior strength.
200 series: An innovative blend of chromium-manganese-nickel.
201,202, etc.: In these varieties, manganese elegantly takes the place of nickel. Despite offering relatively lower corrosion resistance, they are widely utilized as affordable alternatives to the premium 300 series within the expansive Chinese market.
300 series: Renowned chromium-nickel austenitic stainless steel, a symbol of quality and resilience.
304: A versatile general model, often referred to as 18/8 stainless steel, celebrated for its corrosion-resistant properties. It finds applications in a diverse array of products, including durable containers, elegant tableware, chic furniture, sturdy railings, and advanced medical equipment. The standard composition is a harmonious blend of 18% chromium and 8% nickel. Notably, it is a non-magnetic stainless steel, whose metallographic structure remains unchanged through heat treatment. The GB grade is 06Cr19Ni10, a marker of excellence.
304 L: Retaining the beloved characteristics of 304, this low-carbon version offers enhanced corrosion resistance and ease of heat treatment. Although its mechanical properties are slightly compromised, it excels in applications requiring welding and scenarios where heat treatment is challenging.
304 N: Sharing the familiar traits of 304, this variant includes nitrogen for heightened strength, making it a robust choice in demanding applications.
309: Pioneering in temperature resistance, this variant performs exceptionally up to a remarkable 980°C, surpassing the capabilities of 304.
309 S: Enriched with substantial chromium and nickel content, this variant offers superb heat resistance and oxidation resilience. It is ideally suited for high-demanding products such as heat exchangers, boiler components, and the advanced domain of jet engines.
310: Mastering high-temperature oxidation resistance, this variant stands out with an impressive maximum operating temperature of 1200°C, a testament to its advanced engineering.
316: Standing just behind 304 in popularity, this exceptional steel grade is a cornerstone in the food industry, essential for watch accessories, and integral to the pharmaceutical and surgical equipment sectors. The addition of molybdenum provides a unique corrosion-resistant structure, offering superior chloride corrosion resistance than 304. As 'marine steel', SS316 is a robust choice for demanding environments, and it prevails in nuclear fuel recovery devices. The esteemed 18/10 grade stainless steel often meets these high standards.
316 L: This low-carbon marvel offers greater corrosion resistance and heat-treatment flexibility. It excels in applications like chemical processing equipment, nuclear power generators, and refrigerant storage tanks, embodying strength and adaptability.
410: A robust martensitic high-strength chromium steel, known for excellent wear resistance. However, its corrosion resistance is less remarkable, making it suitable for specific applications.
420: Heralded as 'Tool-grade', this martensitic steel resembles Brinell high-chromium steel and holds the distinction of being the earliest stainless steel. It finds use in precision instruments like surgical knives and can achieve a highly polished finish, reflecting its versatile nature.
