Shanghai Bolaisheng Metal Group Co., Ltd. proudly presents its exceptional offering, the versatile 200 Series Seamless Stainless Steel Pipe, designed to excel in the chemical industry. This hollow cylindrical marvel of engineering serves a multitude of industries, stretching from petroleum and chemical to medical, food, light industry, and mechanical instrumentation. Celebrated for its impressive strength in both bending and torsion, while maintaining a lightweight profile, it stands as an ideal choice for crafting precision mechanical parts, robust engineering structures, and even chic furniture and kitchenware.
Delve into the elegant complexity of our stainless steel offerings, meticulously categorized by composition: from the classic Cr series (400 series) to the sophisticated Cr-Ni series (300 series), and innovative Cr-Mn-Ni (200 series), not forgetting the resilient heat-resistant chromium alloy steel (500 series) and the advanced precipitation hardening series (600 series). Each variant is crafted to meet the unique demands of diverse industrial applications.
200 Series: Embodying the cutting-edge of chromium-manganese-nickel alloy technology, the 200 Series presents an innovative blend that enhances versatility and application.
201, 202, etc.: With ingenuity, manganese takes the place of nickel, offering a cost-effective alternative with relative corrosion resistance. This series is prevalent as an economical substitute for the 300 series within China, catering to price-sensitive markets.
300 Series: Experience the sophistication of chromium-nickel austenitic stainless steel, renowned for its premium quality and exceptional applications across a variety of industries.
304: This iconic general model represents the hallmark of 18/8 stainless steel, revolutionizing products like corrosion-resistant containers, elegant tableware, modern furniture, sturdy railings, and precise medical equipment. With a standard composition of 18% chromium and 8% nickel, 304 is a non-magnetic marvel whose metallurgical structure remains unchanged even under heat treatment. Known in the GB grade as 06Cr19Ni10, it exemplifies unmatched quality.
304 L: This variant mirrors the esteemed 304 but with reduced carbon content, enhancing its resistance to corrosion and ease of heat treatment, while maintaining excellent weldability. It is the go-to choice for applications requiring welding and those less amenable to heat treatment.
304 N: Sharing the attributes of the renowned 304, this nitrogen-fortified stainless steel elevates strength, showcasing the innovative synergy between alloy components.
309: Offering superior temperature resilience compared to the 304, the 309 variant shines under intense heat, enduring temperatures up to 980°C with remarkable reliability.
309 S: Enriched with abundant chromium and nickel, this variant boasts exceptional heat and oxidation resistance, making it ideal for demanding applications such as heat exchangers, boiler components, and jet engines.
310: This extraordinary stainless steel showcases excellent high-temperature oxidation resistance, boasting a formidable maximum operating temperature of 1200°C, redefining expectations.
316: Following the esteemed 304, the 316 grade enjoys widespread usage, especially within the food industry, watch accessories, pharmaceutical sector, and surgical equipment. The addition of molybdenum confers a unique corrosion-resistant structure, particularly effective against chloride. Known as 'marine steel,' SS316 finds applications in nuclear fuel recovery, exemplifying the 18/10 grade stainless steel standards.
316 L: With its low carbon content, this variant enhances corrosion resistance and ease of heat treatment, making it ideal for chemical processing equipment, nuclear power generators, and refrigerant storage tanks.
410: Step into the realm of martensitic (high-strength chromium steel) with excellent wear resistance, albeit with limited corrosion resistance, perfect for specific high-demand applications.
420: Known as 'tool-grade' martensitic steel, akin to Brinell high-chromium steel, 420 is celebrated as the earliest stainless steel, adept for surgical knives, capable of achieving a lustrous finish.
