Introducing our exceptional stainless steel pipe, a versatile, hollow, cylindrical marvel designed to excel across a wide array of industries. From petroleum and chemical sectors to medical, food, light industry, and mechanical instrumentation, this pipe shines with its unrivaled strength in both bending and torsion. Despite its incredible durability, it boasts a lightweight nature, making it the ideal choice for crafting intricate mechanical parts, robust engineering structures, and even sophisticated furniture kitchenware.
According to its composition, our stainless steel can be elegantly categorized into the Cr series (400 series), the Cr-Ni series (300 series), the Cr-Mn-Ni series (200 series), heat-resistant chromium alloy steel (500 series), and the precipitation hardening series (600 series).
200 series: Crafted with chromium-manganese-nickel, offering a balanced blend of properties.
201,202, etc.: Ingeniously designed with manganese as a substitute for nickel, these variants offer economical solutions with moderate corrosion resistance, widely adopted as cost-effective alternatives to the 300 series in China.
300 series: Premium chromium-nickel austenitic stainless steel, celebrated for its exceptional qualities.
304: The quintessential model of 18/8 stainless steel, renowned for crafting corrosion-resistant containers, elegant tableware, sophisticated furniture, secure railings, and medical equipment. This non-magnetic stainless steel, with a standard composition of 18% chromium plus 8% nickel, remains unchanged by heat treatment, aligning with the GB grade 06Cr19Ni10.
304 L: Retains the admirable characteristics of 304, enhanced with low carbon for superior corrosion resistance and ease of heat treatment, though with slightly diminished mechanical properties. It excels in welding applications and products that are not heat treatable.
304 N: Mirroring 304's traits, this nitrogen-enriched variant elevates steel strength, making it a formidable choice.
309: Designed for enhanced temperature resistance, performing reliably up to 980°C.
309 S: Enriched with abundant chromium and nickel, showcasing outstanding heat and oxidation resistance, ideal for heat exchangers, boiler components, and jet engines.
310: Distinguished for superb high-temperature oxidation resistance, withstanding up to a remarkable 1200°C.
316: Second only to 304 in widespread use, predominantly in the food industry, luxury watch accessories, pharmaceuticals, and surgical equipment. Infused with molybdenum, it boasts a unique corrosion-resistant structure, excelling in chloride environments as "marine steel". SS316's reliability extends to nuclear fuel recovery devices, typically meeting the 18/10 grade stainless steel standards.
316 L: Featuring low carbon content, this variant offers enhanced corrosion resistance and ease in heat treatment, perfect for chemical processing equipment, nuclear power generators, and refrigerant storage tanks.
410: A martensitic marvel, this high-strength chromium steel shines with robust wear resistance, though with limited corrosion resistance.
420: Known as "tool-grade" martensitic steel, akin to Brinell high-chromium steel, this pioneering stainless steel variant is celebrated for surgical knives, delivering brilliant shine and resilience.
