Introducing our premium stainless steel pipe, a marvel of engineering that embodies versatility and resilience. This hollow cylindrical steel stands as a pillar in numerous sectors, including petroleum, chemical processing, healthcare, food production, light industry, and mechanical instrumentation. Celebrated for its remarkable strength in both bending and torsion while maintaining a lightweight profile, it is the material of choice for crafting resilient mechanical parts, robust engineering structures, and aesthetically pleasing furniture kitchenware.
In the world of stainless steel, composition is key! Our products are expertly categorized into various series: Cr series (400 series), Cr-Ni series (300 series), Cr-Mn-Ni series (200 series), heat-resistant chromium alloy steel (500 series), and the cutting-edge precipitation hardening series (600 series), each tailored to meet the diverse needs of modern industry.
200 series: A sophisticated blend of chromium, manganese, and nickel.
201, 202, etc.: In this series, manganese takes the place of nickel, resulting in relatively lower corrosion resistance but offering a cost-effective alternative to the 300 series, especially popular in China.
300 series: Renowned chromium-nickel austenitic stainless steel, known for its exceptional performance.
304: The quintessential model, known as 18/8 stainless steel, serves a multitude of applications such as corrosion-resistant containers, tableware, furniture, railings, and medical equipment. It features a standard composition of 18% chromium and 8% nickel. This non-magnetic stainless steel retains its metallographic structure despite heat treatment. The GB grade is 06Cr19Ni10, marking its excellence.
304 L: Sharing the core attributes of 304, this variant offers enhanced corrosion resistance due to its lower carbon content, making it ideal for welding applications and products that do not require heat treatment, despite having less robust mechanical properties.
304 N: A nitrogen-infused version of 304, designed to bolster the steel's strength while maintaining its fundamental characteristics.
309: This variant surpasses 304 in temperature resistance, enduring up to a remarkable 980°C.
309 S: Fortified with substantial chromium and nickel, this stainless steel excels in heat and oxidation resistance, making it perfect for applications in heat exchangers, boiler components, and jet engines.
310: Known for outstanding high-temperature oxidation resistance, this variant performs exceptionally well with a maximum operating temperature reaching an impressive 1200°C.
316: A stellar performer following 304 in popularity, this grade is predominantly utilized in the food industry, watch accessories, pharmaceuticals, and surgical instruments. Enhanced with molybdenum, it offers superior corrosion resistance, especially against chlorides, earning its title as 'marine steel'. SS316 finds its purpose in nuclear fuel recovery systems, with the 18/10 grade meeting these high standards.
316 L: Featuring low carbon content, this variant enhances corrosion resistance and simplifies heat treatment. It is ideal for crafting chemical processing equipment, nuclear power generators, and refrigerant storage tanks.
410: A martensitic variant known for its high-strength chromium composition, this steel offers superb wear resistance, though its corrosion resistance is comparatively lower.
420: Dubbed 'Tool-grade' martensitic steel, it bears similarity to Brinell's high-chromium steel and stands as one of the earliest forms of stainless steel. It is famed for its application in surgical knives, polished to a brilliant shine.
