Our premium 304L Stainless Steel Pipe, a marvel of versatile engineering, is meticulously crafted to meet the demands of diverse industries such as petroleum, chemical, medical, food, light industry, and mechanical instrumentation. This hollow cylindrical steel is celebrated for its unparalleled strength in bending and torsion, yet maintains a lightweight profile, making it an ideal choice for the creation of intricate mechanical parts, robust engineering structures, and even elegant furniture and kitchenware.
According to its sophisticated composition, this stainless steel can be classified into several distinctive series: Cr series (400 series), Cr-Ni series (300 series), Cr-Mn-Ni series (200 series), heat-resistant chromium alloy steel (500 series), and precipitation hardening series (600 series). Each series offers unique attributes tailored to specific industrial applications.
200 series: A robust combination of chromium, manganese, and nickel, this series is renowned for its specialized composition, providing strength and versatility.
201, 202, etc.: In these grades, manganese artfully replaces nickel, offering a budget-friendly alternative with relatively lower corrosion resistance-widely embraced across China as a cost-effective substitute for the more premium 300 series.
300 series: Encompassing chromium-nickel austenitic stainless steel, this series is esteemed for its superior corrosion resistance and versatility across various applications.
304: This general model, often referred to as 18/8 stainless steel, is indispensable for crafting corrosion-resistant containers, tableware, furniture, railings, and medical equipment. Boasting a solid metallographic structure of 18% chromium and 8% nickel, it remains non-magnetic and immune to heat treatment alterations. The GB grade is 06Cr19Ni10.
304L: Bearing the same impressive characteristics as 304, this low-carbon variant enhances corrosion resistance and is easily heat-treated, simplifying welding and making it perfect for projects where heat treatment is challenging.
304N: Elevating the strengths of 304, this nitrogen-infused stainless steel is designed to deliver enhanced durability and robustness, thanks to its increased nitrogen content.
309: This grade excels in temperature resistance, effortlessly withstanding extreme conditions up to 980°C, making it ideal for high-heat applications.
309S: With an abundance of chromium and nickel, this variant offers remarkable heat and oxidation resistance, perfect for components such as heat exchangers, boiler parts, and jet engines.
310: Celebrated for its exceptional high-temperature oxidation resistance, this grade is engineered to perform optimally at soaring temperatures of up to 1200°C.
316: Second only to 304 in popularity, 316 is predominantly utilized in the food industry, watchmaking, pharmaceuticals, and surgical equipment. The addition of molybdenum enriches its structure, providing exceptional resistance to chloride corrosion, earning it the title of "marine steel". SS316 is extensively trusted in nuclear fuel recovery devices, with the 18/10 grade meeting stringent applications.
316L: This low-carbon variant boasts superior corrosion resistance and can be effortlessly heat-treated, ideal for advanced chemical processing equipment, nuclear power generators, and refrigerant storage tanks.
410: A martensitic marvel, this high-strength chromium steel is renowned for its excellent wear resistance, though its corrosion resistance may be limited.
420: Known as "tool-grade" martensitic steel, this variant mirrors Brinell high-chromium steel and stands as one of the earliest forms of stainless steel, perfect for surgical knives with its high-shine finish.
