The stainless steel tube from Shandong Tata Iron and Steel Co., Ltd. is meticulously classified into several series to cater to diverse industrial needs. These classifications include the Cr system (400 series), Cr-Ni system (300 series), Cr-Mn-Ni system (200 series), and the precipitation hardening system (600 series). The 200 series is noted for its chrome-nickel-manganese austenitic stainless steel composition, while the 300 series features chrome-nickel austenitic stainless steel.
301-----301 stainless steel is renowned for its excellent extension properties, making it ideal for molding products. It also hardens through mechanical processing, offers good weldability, and boasts superior wear resistance and fatigue strength compared to 304 stainless steel.
302-----302 stainless steel shares similar corrosion resistance with 304, but its relatively higher carbon content provides enhanced strength.
303-----303 stainless steel is optimized for easy cutting by incorporating small amounts of sulfur and phosphorus, making it more machinable than 304.
304-----304 stainless steel, known as 18/8 stainless steel, corresponds to the GB grade 0Cr18Ni9. Additionally, 309 stainless steel offers better temperature resistance than 304.
316-----After 304, 316 is the second most widely used steel grade. It is predominantly used across the food and pharmaceutical industries, as well as in surgical equipment. The addition of molybdenum provides a unique structure highly resistant to corrosion.
321 - 321 stainless steel shares similar properties with 304, but the addition of titanium significantly reduces the risk of weld corrosion.
400 series - The 400 series encompasses ferritic and martensitic stainless steels.
408-408 stainless steel stands out with its excellent heat resistance and weak corrosion resistance, containing 11% Cr and 8% Ni.
409-409 stainless steel is the most economical model, frequently used in automotive exhaust systems. It is classified as ferritic stainless steel or chrome steel.
410-410 stainless steel is a martensitic high-strength chrome steel known for good wear resistance but limited corrosion resistance.
416-416 stainless steel benefits from the addition of sulfur, which enhances its processing properties.
420-420 stainless steel is known as 'cutting grade' martensitic steel and is akin to the earliest Brinell high-chromium steels. Commonly used for surgical knives, it can achieve a very bright finish.
430 -430 stainless steel is a ferritic type frequently used in decorative applications, such as automotive accessories. It offers good formability but limited temperature and corrosion resistance.
440-440 stainless steel is a high-strength cutting tool steel with a slightly higher carbon content. With appropriate heat treatment, it can achieve high yield strength and hardness up to 58HRC, making it one of the hardest stainless steels available. Common applications include razor blades, with three popular models: 440A, 440B, 440C, and the easy-to-process 440F.
500 series - This series includes heat-resistant chrome alloy steels.
600Series - The 600 series features martensitic precipitation-hardened stainless steel tubes.
