Stainless Steel Coil is a rolled metal product made from stainless steel, renowned for its excellent corrosion resistance, high strength, and aesthetic appeal. It comes in various grades like 304, 316, etc., and finishes such as 2B, BA, or mirror. Widely used in construction, automotive, appliances, and more, it offers durability and easy fabrication, making it ideal for diverse industrial and decorative applications.

304 stainless steel coil is a classic grade of austenitic stainless steel, containing 18% chromium (Cr) and 8% nickel (Ni), with both corrosion resistance and processing performance. It is non-magnetic (weak after cold working) and has excellent ductility. It can be stamped, bent, and welded to meet the needs of multiple scenarios. The surface can be processed into 2B matte, BA bright surface or brushed texture, which is both beautiful and practical. It is widely used in food equipment, building curtain walls, home appliance housings, medical equipment and chemical pipelines, and is an industrial basic material with outstanding cost performance.

304L stainless steel coil is a low-carbon austenitic stainless steel with a chemical composition similar to 304 (Cr18%, Ni8%), but the carbon content is ≤0.03%, which significantly reduces the risk of intergranular corrosion in the heat-affected zone of welding. Its corrosion resistance, ductility and deep drawing performance are comparable to 304, but its low-temperature toughness is better (it still maintains plasticity at -196℃), and no solution treatment is required after welding. It is widely used in chemical storage tanks, pressure vessels, food-grade pipelines and coastal building structures, especially suitable for harsh corrosive environments that require welding processing. It is an engineering material of choice that takes into account both economy and reliability.

316 stainless steel coil is a high-performance metal material with an austenite structure and 2%-3% molybdenum (Mo) added. With its super strong resistance to chloride ion corrosion, it has become the preferred material in the fields of marine engineering, chemical equipment, medical equipment and food processing. The addition of molybdenum forms a dense passivation film on the metal surface, which can effectively resist the erosion of seawater, acidic solutions and high-salt fog environments. The corrosion resistance is 2-3 times higher than that of 304 stainless steel, and the mechanical properties are stable in a wide temperature range of -196℃ to 850℃. It has both low-temperature toughness and high-temperature strength, and is suitable for complex process scenarios.

316L stainless steel coil is a low-carbon (≤0.03% C) variant of 316 austenitic alloy, engineered to eliminate welding-induced corrosion risks while delivering unmatched durability in harsh environments. Its molybdenum (2%-3% Mo) content, paired with ultra-low carbon, ensures resistance to pitting, crevice, and intergranular attack in chlorinated media (seawater, saline spray) and aggressive chemicals (acids, alkalis). Withstanding cryogenic (-196°C) brittleness and thermal stability (up to 850°C), it excels in marine equipment, biopharmaceutical reactors, cryogenic vessels, and chemical pipelines where flawless weld integrity and corrosion-free longevity are critical, outlasting 304L by 2-3x in service life.

321 stainless steel coil is an austenitic alloy fortified with titanium (Ti) stabilization (0.3-0.7% Ti) to combat carbide precipitation during welding and high-temperature exposure, making it ideal for thermal-cyclic and corrosive-heat environments. By anchoring carbon via titanium, it retains corrosion resistance in oxidizing media (e.g., nitric acid, steam) while preventing intergranular corrosion at 550–900°C, outperforming 304 in heat-affected zones.

310S stainless steel coil is a high chromium-nickel austenitic heat-resistant stainless steel, containing 25% chromium and 20% nickel, with excellent oxidation resistance and high temperature strength, and can be used continuously below 1150°C. Its low carbon content (≤0.08%) effectively prevents intergranular corrosion, and the stable austenitic structure ensures dimensional stability at high temperatures. The material has good processing performance, is easy to weld and form, and is widely used in heat-resistant parts such as heat treatment furnace tubes, burners, and high-temperature heat exchangers. It is an ideal choice for high-temperature equipment in petrochemical, electric power, metallurgy and other industries.

430 stainless steel coil is an economical ferritic stainless steel containing 16-18% chromium, with good corrosion resistance and formability. This material is magnetic and has better oxidation resistance than 304 stainless steel, but is slightly weaker in acid and alkali resistance. 430 stainless steel coil has excellent processing performance and is suitable for deep drawing, bending and other processes. It is widely used in cost-sensitive fields such as home appliance panels, building decoration, and automobile exhaust pipes. Its surface can be polished, brushed and other treatments to obtain good decorative effects, making it an economical alternative to 304 stainless steel.

439 stainless steel coil is a titanium stabilized ferritic stainless steel. Titanium (Ti≥0.15%) is added to 430 to improve weldability and intergranular corrosion resistance. The material contains 17-19% chromium, has excellent high temperature oxidation resistance and stress corrosion cracking resistance, and the working temperature can reach 800℃. Its formability and weldability are better than ordinary ferritic stainless steel. It is widely used in automotive exhaust systems, water heater liner, kitchen utensils and other fields that require heat resistance and corrosion resistance. It is an environmentally friendly stainless steel material with excellent cost performance.

444 stainless steel coil is a molybdenum-containing ferritic stainless steel with 18-20% chromium and 2% molybdenum. It has excellent resistance to chloride ion corrosion and pitting corrosion. The corrosion resistance of this material is close to that of 316L stainless steel, and its thermal conductivity is better than that of austenitic steel. It is particularly suitable for humid environments such as water treatment equipment and water heater tanks. It has a small thermal expansion coefficient and good welding performance. After stabilization treatment, it can also be used in automobile exhaust systems. It is an environmentally friendly material that is both corrosion-resistant and economical.

2205 stainless steel coil is a typical duplex stainless steel, composed of about 50% austenite and 50% ferrite, containing 22% chromium, 5% nickel and 3% molybdenum. This unique duplex structure gives it excellent mechanical properties and corrosion resistance. Its tensile strength can reach 2 times that of ordinary austenitic stainless steel, and it also has excellent resistance to stress corrosion cracking. It is widely used in harsh environments such as marine engineering, petrochemicals, and desulfurization equipment. Its good weldability and processing properties make it an ideal material choice that takes into account both strength and corrosion resistance.

2507 stainless steel coil is a super-duplex alloy (25% Cr, 7% Ni, 4% Mo, 0.3% N) engineered for extreme corrosion and mechanical demands, blending the strength of ferrite with the toughness of austenite. Its dual-phase structure and high molybdenum/nitrogen content deliver 4x pitting resistance of 316L, thriving in chlorinated seawater, acidic oilfield brines, and pulp bleach solutions while resisting stress corrosion cracking (SCC).
