Types 309 Stainless Steel and 309S are austenitic chromium-nickel stainless steels that provide excellent corrosion resistance and heat resistance plus good strength at room and elevated temperatures.
They are essentially nonmagnetic as annealed and become lightly magnetic when cold worked.
| 309/309s Stainless Steel Plates Specification | ASTM A240 / ASME SA240 |
| 309/309s Stainless Steel Plates Manufacturing Process | Hot Rolled (HR) / Cold Rolled (CR) |
The 309 stainless steel has a higher corrosion resistance and strength compared to 304 stainless steel. This product is versatile and known for its high heat treatment capabilities.
