SUS316L yarn and SUS316L sewing thread are made of 316L stainless steel fiber, so the yarn has good heat resistance characteristics, and can be used to sew fire blankets.
SUS316L is a kind of stainless steel containing molybdenum. Due to the molybdenum in the steel, the overall performance of this steel is better than 310 and 304 stainless steel. At high temperature, when the concentration of sulfuric acid is less than 15% or higher than 85%, 316L stainless steel has a wide range of uses. 316L stainless steel thread also has good resistance to chloride corrosion, so it is usually used in marine environment.
The melting point of 316L stainless steel is 1375-1450C degrees, which can work in a high temperature environment of 650-700C degrees for a long time and still has good performance.
