Product Description

Our stainless steel pipe stands as a marvel of industrial prowess-a versatile, hollow cylindrical marvel of steel-exemplifying its prowess across a myriad of industries. From the realms of petroleum and chemical domains to the intricate worlds of medical, food, and light industries, and even mechanical instrumentation, it is a paragon of strength. Renowned for its exceptional capacity to withstand bending and torsion forces while maintaining a lightweight profile, this steel pipe emerges as an indispensable ally in the crafting of mechanical parts and engineering marvels, as well as in the creation of sophisticated furniture and kitchenware.
The composition of our stainless steel marvels allows them to be elegantly classified into distinct series, each with its own unique attributes. Revel in the Cr series (400 series), the Cr-Ni series (300 series), Cr-Mn-Ni (200 series), the heat-resistant chromium alloy steel (500 series), and the innovative precipitation hardening series (600 series), each crafted to meet the specific demands of modern engineering and design.
200 series: Featuring chromium-manganese-nickel, this series shines with its unique blend of elements, engineered for specialized applications.
201, 202, etc.: Within this series, manganese artfully replaces nickel, offering a budget-friendly alternative with relatively limited corrosion resistance. It stands as a widely used economic substitute for the 300 series in China.
300 series: Embrace the excellence of chromium-nickel austenitic stainless steel, a hallmark of durability and innovation in the world of stainless solutions.
304: The quintessential general model, known as 18/8 stainless steel, finds its place in a multitude of applications including corrosion-resistant containers, elegant tableware, stylish furniture, sturdy railings, and advanced medical equipment. With a standard composition of 18% chromium and 8% nickel, this non-magnetic stainless steel maintains its metallographic structure without heat treatment. Its GB grade is 06Cr19Ni10.
304 L: Sharing the same magnificent characteristics as 304, this variant boasts low carbon content, enhancing its corrosion resistance and ease of heat treatment. However, its mechanical properties are modest, making it ideal for welding and products that resist heat treatment.
304 N: Mirroring the characteristics of 304, this nitrogen-infused variant elevates the strength of the stainless steel, opening new avenues for innovation and strength.
309: When it comes to temperature resistance, 309 outshines 304, withstanding temperatures up to 980°C, thus catering to more demanding applications.
309 S: Enhanced with generous amounts of chromium and nickel, this variant excels in heat resistance and oxidation resistance, ideal for products such as heat exchangers, boiler components, and the rigorous environments of jet engines.
310: This elite variant boasts exceptional high-temperature oxidation resistance, operating at impressive temperatures up to 1200°C, making it the choice for extreme conditions.
316: As the second most utilized steel grade following 304, 316 asserts its dominance in the food industry, watch accessory realm, pharmaceutical industry, and surgical equipment. The inclusion of molybdenum forms a special corrosion-resistant structure, notably surpassing 304 in chloride corrosion resistance, earning its reputation as 'marine steel.' SS316 finds its niche in nuclear fuel recovery devices, with 18/10 grade stainless steel meeting these stringent application levels.
316 L: With its low carbon content, this variant not only enhances corrosion resistance but also facilitates heat treatment, becoming an indispensable component in chemical processing equipment, nuclear power generation, and refrigerant storage tanks.
410: Known for its martensitic structure, this high-strength chromium steel boasts excellent wear resistance, though its corrosion resistance is modest.
420: Celebrated as 'tool-grade' martensitic steel, akin to Brinell high-chromium steel, this pioneer in stainless steel history finds its application in surgical knives, capable of attaining remarkable brightness.
