309/309S Stainless Steel Bar Description
309 stainless steel bar is made of an austenitic stainless steel containing substantial chromium and nickel content. 309 stainless steel bars are highly resistant to various corrosive media, including acid, alkali, salt and other solutions, as well as organic solvents. They can still show outstanding corrosion resistance at high temperatures and can work stably for a long time in high-temperature environments. So high-temperature equipment in aviation, chemical industry is where they are often adopted. 309 stainless steel bars can be formed and welded through various processing methods due to its outstanding processing performance. Lastly, 309 stainless steel bars are non-magnetic and suitable as manufacturing parts and components without magnetic requirements.
