304 stainless steel wire is a widely - used material. It is made of austenitic stainless steel. Composed mainly of iron, chromium (about 18%) and nickel (about 8%), this composition gives it excellent corrosion resistance. It can withstand exposure to various environments, including moisture and mild chemicals.

309S stainless steel wire is an important type of stainless steel wire. It contains a relatively high amount of chromium (around 22 - 24%) and nickel (about 12 - 15%).
This composition endows it with remarkable properties. It has excellent heat resistance, which enables it to withstand high - temperature environments without significant deformation or degradation. It also shows good corrosion resistance, especially in moderately corrosive conditions.

316 Stainless Steel Wire is a highly versatile and corrosion-resistant material widely used across various industries due to its exceptional properties. This type of stainless steel wire is composed primarily of chromium, nickel, and molybdenum, which contribute significantly to its outstanding performance in harsh environments.

420 Stainless Steel Wire, also known as UNS S42000, is a martensitic stainless steel grade renowned for its exceptional hardness, moderate corrosion resistance, and good wear resistance. It is a chromium-based alloy with a minimum of 12% chromium content, which gives it the ability to withstand certain corrosive environments, albeit to a lesser extent compared to austenitic grades like 304 or 316.
