INTRODUCTION
● 309 stainless steel coil
1) 309 stainless steel coil has better corrosion resistance and heat resistance than 304, can withstand repeated heating below 980 °C, and has higher high temperature strength, oxidation resistance and carburization resistance.
2) 309 stainless steel coil is a free-cutting stainless steel containing sulfur, which is used in applications where free-cutting and high surface finish are mainly required.
3) 309 stainless steel coil- S30908 (American AISI, ASTM) The corresponding Chinese grade of 309 is 0Cr23Ni13.
