Stainless steel wire is a variety of different sizes and types of stainless steel wire products that are generally round or flat in cross-section. Good corrosion resistance. It can be divided into stainless steel wire for springs, stainless steel wire for rope making, stainless steel wire for welding, stainless steel wire for braiding, etc. Stainless steel wire for different purposes has different requirements in terms of diameter, strength, toughness, etc..

Type 201 stainless steel is a low-cost alternative to traditional chromium-nickel stainless steels such as 301 and 304, where the nickel is replaced by added manganese and nitrogen.Type 201 is essentially non-magnetic in the annealed condition, but becomes magnetic after cold working and can achieve high tensile strengths.Type 201 can be used as a replacement for Type 301 in many applications. It is used primarily for decorative piping, industrial piping, and some shallow drawn products.

302 stainless steel is an austenitic stainless steel containing 18% chromium and 8% nickel. This alloy is the most common and most commonly used alloy in the stainless steel family. 302 is a slightly higher carbon version of 304 and is usually available in strip and wire form. It is a tough steel with high corrosion resistance, non-magnetic and has high fabrication and formability. Common 302 stainless steel wire diameters typically range from 0.033cm (0.013 inches) to 1.5875cm (0.625 inches) in different sizes such as 0.0356cm, 0.0381cm, 0.0399cm, etc., although it can be customized to meet specific needs.

Grade 303 stainless steel, also known as 1.4305 stainless steel, has a high sulphur content making it one of the easiest of all the austenitic stainless steels to work with. 303 stainless steel has a lower corrosion resistance than 304 stainless steel but its toughness is still as good as any other austenitic stainless steel.
303 stainless steel wire is available in a wide range of sizes, usually from 0.08mm - 10.0mm in diameter, depending on the application and processing requirements. Commonly available are 0.1mm, 0.2mm, 0.3mm, 0.5mm, 1.0mm, 2.0mm, etc. Non-standard specifications of stainless steel wire can also be customized according to the special needs of customers.

304 stainless steel is a general-purpose stainless steel material with better rust resistance than 200 series stainless steel materials. High temperature resistance is also better, up to 1000-1200 degrees.304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance, high strength and toughness, smooth and beautiful surface, easy to process. It is mainly used in building decoration, kitchenware and tableware, food processing equipment, medical equipment, chemical equipment, automobile parts and so on.

Compared with 304 stainless steel, 316 stainless steel has a molybdenum content of 2-3%, which makes it more resistant to corrosion by acids, alkalis, salts and other chemicals, and is especially resistant to chlorides, which makes it suitable for a variety of harsh corrosive environments. It is usually used in pulp and paper equipment, heat exchangers, dyeing equipment, film processing equipment, pipelines, building exterior materials in coastal areas, and bracelets and cases of high-grade watches.
