stainless steel coil, as a low carbon 304 steel, 304L Stainless Steel Coil, in general, the corrosion resistance is similar to 304, but after welding or after stress relief, its resistance to grain boundary corrosion is excellent.
The important elements in stainless steel coils are Ni and Cr, but they are not limited to these two elements. Specific requirements are specified by product standards. The common judgment situation in the industry is that as long as the Ni content is greater than 8%, the Cr content is greater than 18%, and the C content is less than or equal to 0.03%, it can be considered as stainless steel. This is why the industry calls this type of stainless steel 18/8 stainless steel. In fact, the relevant product standards have very clear regulations for , and these product standards have some differences for different shapes of stainless steel. Below are some common product standards and tests.
Tensile strength σb (MPa)≥520 Conditional yield strength σ0.2 (MPa)≥205 Elongation δ5 (%)≥40 Area shrinkage ψ (%)≥60 Hardness: ≤187HB;≤90HRB;≤200HV

stainless steel coil has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. Corrosion resistance in the atmosphere, if it is an industrial atmosphere or heavily polluted area, it needs to be cleaned in time to avoid corrosion. stainless steel coil has good processability and weldability, suitable for food processing, storage and transportation. It is often used in plate heat exchangers, corrugated pipes, household products, building materials, chemicals, food industries and other industries. stainless steel coil is nationally recognized food grade stainless steel.
