In addition, 410 stainless steel coil has a relatively low cost and is a cost-effective industrial material choice.

430 stainless steel coil is a ferritic stainless steel coil with good corrosion resistance, especially in oxidizing acid environment. It is relatively cheap, has a small thermal expansion coefficient and good thermal stability, and is suitable for manufacturing home appliance housings, kitchen utensils, architectural decorations and automotive exhaust system components. However, its strength and toughness are slightly lower than austenitic stainless steel, and it is suitable for scenes where strength requirements are not stringent.

439 stainless steel coil is a ferritic stainless steel coil with excellent corrosion resistance, especially suitable for environments sensitive to chloride stress corrosion cracking. This material has excellent formability and weldability, low thermal expansion coefficient and good thermal conductivity. It is suitable for automotive exhaust systems, water heater tanks and architectural decoration. It is an economical material choice that takes into account both performance and cost.

2507 stainless steel coil is a super duplex stainless steel coil with high chromium, high molybdenum and high nitrogen content, and has the advantages of austenite and ferrite duplex structure. Its yield strength exceeds 800MPa, pitting resistance equivalent (PREN) ≥40, and it has excellent corrosion resistance to chloride, sulfuric acid and seawater. It is suitable for extreme corrosive environments such as deep-sea oil and gas production, flue gas desulfurization equipment, and high-salt chemical equipment. It is an ideal choice for high-performance corrosion-resistant materials.

201 stainless steel wire is an economical chromium-manganese stainless steel wire, containing 16-18% chromium and 3.5-5.5% nickel, with moderate corrosion resistance and good formability. Its tensile strength reaches 700-900MPa, suitable for non-harsh environment applications such as interior decoration, hardware products, and ordinary springs. Compared with 304 stainless steel, it has lower cost, but slightly weaker corrosion resistance and is not suitable for long-term exposure to humid or corrosive environments.

202 stainless steel wire is a chromium-manganese-nickel austenitic stainless steel wire, containing 17-19% chromium, 4-6% nickel and 7.5-10% manganese, with better corrosion resistance and mechanical properties than 201 steel. Its tensile strength is 750-950MPa, suitable for moderately corrosive environments such as building decoration, home hardware, kitchenware accessories, etc. Its cost-effectiveness is between 201 and 304, but it still needs protective treatment for long-term outdoor use.

302 stainless steel wire is a basic type of austenitic stainless steel with 18% chromium and 8% nickel. It has excellent formability, weldability and moderate corrosion resistance. Its tensile strength after cold working can reach more than 1000MPa, which is suitable for industrial fields such as springs, medical equipment, and precision hardware. Compared with 304 stainless steel, it has a slightly higher carbon content, better hardness but slightly inferior corrosion resistance, and is not suitable for long-term use in strong corrosive environments.
