420 stainless steel plate is a martensitic stainless steel, containing 12-14% chromium and a relatively high carbon content (0.15-0.40%), and is known for its excellent hardness (HRC50+) and wear resistance. After heat treatment, it has excellent edge retention and is widely used in surgical instruments, knives, bearings and other precision parts. Although its corrosion resistance is slightly inferior to 304, its surface corrosion resistance can be significantly improved through polishing or plating, making it one of the preferred materials in the medical and tool industries.

430 stainless steel plate is a typical ferritic stainless steel, containing 16-18% chromium, with good corrosion resistance, formability and thermal conductivity. Although it does not contain nickel, its corrosion resistance is slightly inferior to 304, but it is cheaper and has excellent stress corrosion resistance. It is widely used in fields with high requirements for surface beauty, such as home appliance panels, kitchen utensils, architectural decoration and automotive accessories, and presents excellent decorative effects after surface treatment.

2205 stainless steel plate is a representative type of duplex stainless steel, containing 22% chromium, 5% nickel and 3% molybdenum, and has both austenite and ferrite characteristics. It has ultra-high strength (twice that of 304) and excellent resistance to chloride stress corrosion, and is suitable for harsh environments such as chemical equipment, offshore platforms, and oil pipelines. Its welding performance and pitting resistance are significantly better than ordinary stainless steel, and it is a special material in the high-end industrial field.

304 Stainless Steel Seamless Pipe is a high-performance tubular product manufactured through hot extrusion or cold drawing processes without any welding seams. Made from premium 304 stainless steel (18% Cr, 8% Ni), it offers excellent corrosion resistance, high strength (tensile strength ≥515MPa), and superior pressure-bearing capacity. With smooth inner/outer surfaces (Ra≤0.6μm) and precise dimensional tolerance (±0.1mm), it's widely used in chemical processing, food & pharmaceutical industries, heat exchangers, and high-pressure fluid systems. Its -196°C~800°C temperature range and ASTM/ASME compliance ensure reliability in demanding applications.

304L Stainless Steel Seamless Pipe is a low-carbon variant (0.03% max C) of 304, offering superior weldability and corrosion resistance. Manufactured through hot/cold forming processes, it maintains excellent mechanical properties (T.S.≥485MPa) while resisting intergranular corrosion. Ideal for chemical processing, LNG systems, and welded components requiring post-weld annealing. Complies with ASTM A312/A358 standards.

316 stainless steel seamless pipe is a premium corrosion-resistant tubular product manufactured through hot extrusion or cold drawing processes. With its 2-3% molybdenum content (16-18% Cr, 10-14% Ni), it delivers exceptional resistance to chlorides, acids, and marine environments, outperforming 304 grades. These pipes feature high tensile strength (≥515MPa), excellent surface finish (Ra≤0.6μm), and reliable performance across extreme temperatures (-196°C to 800°C). They're widely used in chemical processing, offshore platforms, pharmaceutical equipment, and high-purity applications where superior durability is required.

316L stainless steel seamless pipe is a low-carbon variant (0.03% max C) of 316 grade, offering superior weldability and enhanced resistance to intergranular corrosion. Manufactured through precision hot/cold forming processes, it maintains 2-3% molybdenum content (16-18% Cr, 10-14% Ni) for exceptional pitting and chloride resistance. With tensile strength ≥485MPa and polished surfaces (Ra≤0.6μm), it's ideal for chemical processing, marine environments, pharmaceutical systems, and welded applications requiring post-fabrication stability.

2205 stainless steel seamless pipe is a duplex-grade material combining austenitic and ferritic structures, delivering exceptional strength (T.S. ≥620MPa) and superior corrosion resistance. With 22% Cr, 5% Ni, and 3% Mo content, it offers twice the yield strength of 316L while maintaining outstanding resistance to chloride stress corrosion and pitting. Manufactured through controlled hot-working processes, these pipes are ideal for offshore oil/gasystems, chemical processing, and high-pressure applications in aggressive environments.

201 stainless steel seamless pipe is a cost-effective chromium-manganese-nickel alloy (16-18% Cr, 3.5-5.5% Ni, 5.5-7.5% Mn) offering moderate corrosion resistance and high strength (T.S. ≥515MPa). Manufactured through precision cold drawing, it provides better mechanical properties than welded alternatives while maintaining good formability. Suitable for decorative applications, low-corrosion environments, and structural components where 304-grade performance isn't required.

202 stainless steel seamless pipe is a chromium-nickel-manganese austenitic alloy (17-19% Cr, 4-6% Ni, 7.5-10% Mn) that balances cost and performance. Delivering higher corrosion resistance than 201 grade (but less than 304), it features tensile strength ≥515MPa and good oxidation resistance up to 850°C. Manufactured through cold-drawn processes, these precision pipes offer smooth surfaces (Ra≤0.8μm) and improved mechanical properties versus welded alternatives. Ideal for decorative architecture, kitchen equipment, and non-marine applications where moderate corrosion resistance suffices.

310S stainless steel seamless pipe is a high-temperature austenitic alloy (25% Cr, 20% Ni) with exceptional oxidation resistance up to 1100°C. Manufactured through precision hot extrusion, it maintains superior creep strength and thermal stability in extreme environments.
