Our stainless steel pipe represents a marvel of engineering-an adaptable, hollow cylindrical steel that serves as a cornerstone across diverse sectors including petroleum, chemical, medical, food, light industry, and mechanical instrumentation. Celebrated for its formidable strength in bending and torsion while maintaining a lightweight profile, it is the perfect choice for crafting mechanical parts, engineering structures, and even furniture kitchenware. Its versatility and strength make it a go-to material for innovative builders and designers.
Stainless steel, a dynamic material, can be classified based on composition into distinct series: Cr series (400 series), Cr-Ni series (300 series), Cr-Mn-Ni (200 series), heat-resistant chromium alloy steel (500 series), and the precipitation hardening series (600 series). Each series offers unique characteristics tailored to specific industrial needs, ensuring optimal performance across various applications.
200 series: chromium-manganese-nickel-a versatile blend offering affordability with performance.
201, 202, etc.: Within this series, manganese substitutes nickel, leading to a lower corrosion resistance profile. Widely embraced in China as a cost-effective alternative to the 300 series, it offers a practical solution for budget-conscious projects.
300 series: chromium-nickel austenitic stainless steel-a benchmark in quality and performance, renowned for its robust properties.
304: Known as the general model, this 18/8 stainless steel variant is a staple in products such as corrosion-resistant containers, tableware, furniture, railings, and medical equipment. With a standard composition of 18% chromium plus 8% nickel, this non-magnetic stainless steel's metallographic structure is immune to alterations by heat treatment. Identified by the GB grade as 06Cr19Ni10, it stands as a symbol of reliability.
304 L: Mirrors the traits of 304 but boasts a low carbon content, enhancing corrosion resistance and ease of heat treatment. Although its mechanical properties are less robust, it excels in applications requiring welding and those that defy heat treatment.
304 N: Similar properties to 304, yet enriched with nitrogen to boost steel strength-an innovation in stainless steel development.
309: Distinguished by superior temperature resistance compared to 304, it withstands heat up to 980°C, offering exceptional performance in high-temperature environments.
309 S: Its high chromium and nickel content endows it with excellent heat and oxidation resistance. This makes it ideal for products such as heat exchangers, boiler components, and jet engines-where durability under extreme conditions is paramount.
310: Exhibits excellent high-temperature oxidation resistance, with a formidable maximum operating temperature of 1200°C, making it indispensable in heat-intensive applications.
316: Following 304, this grade is highly utilized, predominantly in the food industry, watch accessories, pharmaceutical equipment, and surgical instruments. The addition of molybdenum bestows a unique corrosion-resistant structure, surpassing 304 in chloride resistance, earning it the moniker 'marine steel'. SS316 is favored in nuclear fuel recovery devices, meeting the rigorous demands of 18/10 grade stainless steel applications.
316 L: With its low carbon profile, this variant enhances corrosion resistance and simplifies heat treatment, making it ideal for chemical processing equipment, nuclear power generators, and refrigerant storage tanks-a testament to its adaptability and reliability in critical applications.
410: A martensitic, high-strength chromium steel offering commendable wear resistance, though its corrosion resistance is limited, making it suited for applications where strength is prioritized over corrosion resistance.
420: Known as 'tool-grade' martensitic steel, akin to Brinell high-chromium steel, it's the pioneer of stainless steels. Renowned for crafting surgical knives, it can be polished to a bright finish, exemplifying its versatility and precision.
