Our stainless steel pipe, a versatile hollow cylindrical marvel, transcends traditional boundaries to shine in diverse industries such as petroleum, chemical, medical, food, light industry, and mechanical instrumentation. Celebrated for its robust ability to withstand bending and torsion while maintaining a lightweight profile, this essential component is the perfect choice for constructing mechanical parts, engineering structures, as well as stylish furniture and kitchenware.
According to its composition, stainless steel can be elegantly categorized into several series: the robust Cr series (400 series), the versatile Cr-Ni series (300 series), the adaptable Cr-Mn-Ni (200 series), the heat-defying chromium alloy steel (500 series), and the innovative precipitation hardening series (600 series).
200 series: A harmonious blend of chromium, manganese, and nickel.
201, 202, etc.: In these alloys, manganese takes the place of nickel, resulting in comparatively lower corrosion resistance. Nonetheless, they serve as cost-effective alternatives to the 300 series in the Chinese market.
300 series: Known for its chromium-nickel composition, this austenitic stainless steel stands as a hallmark of quality.
304: The quintessential stainless steel, often referred to as 18/8, is widely used in corrosion-resistant containers, elegant tableware, stylish furniture, sturdy railings, and medical equipment. Its standard composition, 18% chromium plus 8% nickel, is non-magnetic and immune to transformation through heat treatment. In the GB grade, it is recognized as 06Cr19Ni10.
304 L: Exhibiting the same magnificent characteristics as 304, this low-carbon variant offers enhanced corrosion resistance and adaptability to heat treatment, albeit with somewhat compromised mechanical properties. It excels in welding applications and is ideal for products that resist heat treatment.
304 N: Mirroring the characteristics of 304, this nitrogen-enhanced stainless steel boasts increased strength, thanks to its nitrogen content.
309: This variant triumphs over 304 with superior temperature resistance, enduring heat up to a remarkable 980°C.
309 S: Rich in chromium and nickel, this steel exhibits exceptional heat and oxidation resistance. It is ideal for high-performance products like heat exchangers, boiler components, and jet engines.
310: Renowned for its superior high-temperature oxidation resistance, this steel can withstand extreme conditions, with a maximum operating temperature reaching a staggering 1200°C.
316: Following the popular 304, 316 stands as the second most widely used steel, predominantly in the food industry, exquisite watch accessories, the pharmaceutical domain, and surgical instruments. Its composition is enhanced with molybdenum for exceptional corrosion resistance, especially against chlorides, earning it the moniker "marine steel." SS316 is a preferred choice for nuclear fuel recovery devices. The esteemed 18/10 grade often aligns with these rigorous applications.
316 L: A low-carbon variant offering superior corrosion resistance and ease of heat treatment. It finds its purpose in chemical processing equipment, nuclear power generators, and refrigerant storage tanks, showcasing its adaptability and resilience.
410: This martensitic stainless steel, infused with high-strength chromium, excels in wear resistance while exhibiting limited corrosion resistance.
420: Known as "tool-grade" martensitic steel, akin to Brinell high-chromium steel, it is the pioneering stainless steel. It is ideally suited for crafting surgical knives and can be polished to an impressive shine.

Application Requirements
Automobile Industry
Within the automotive industry, stainless steel plays a pivotal role, primarily enhancing exhaust systems, constituting over half of the stainless steel used in vehicles. Ferritic stainless steel reigns supreme, with components like mufflers and converters predominantly utilizing 409L and 436L stainless steel welded pipes. Approximately 1.5% of the total stainless steel pipe consumption is linked to the automotive sector, with a seamless-to-welded pipe usage ratio of about 2:1.
Petrochemical and Fertilizer Industry
The petrochemical industry exhibits a substantial appetite for stainless steel pipes, favoring the seamless variety. Popular specifications such as 304, 321, 316, 316L, 347, and 317L, with outer diameters ranging from 18mm to 610mm and wall thicknesses from 6mm to 50mm, are extensively utilized in applications like furnace tubes, material conveying tubes, and heat exchanger tubes, especially for medium and low-pressure pipelines.
Water and Gas Fluid Transport
Stainless steel pipes are the pinnacle choice for fluid transport systems, offering unmatched corrosion resistance. Compared to cast iron, carbon steel, and plastic alternatives, these pipes lead the charge as the most advanced water purification materials globally.
With stainless steel pipes, the water industry has found its ideal material. These pipes excel in water preparation, storage, transportation, purification, regeneration, and desalination. Annually, the demand reaches an impressive 25,000 tons.
