430S15、430S17、 430S18、Z8C17

characteristic

430S15 stainless steel can not resist the oxidation caused by chemicals in the air. Due to the increasing number of acidic chemicals in the air, 430S15 stainless steel will still be oxidized (rusted) due to unnatural factors after being used for a period of time. .

 

use

1) Decorative materials and outdoor publicity advertising columns;

2) For products with anti-stress corrosion requirements;

3) Electronics, tableware, bolts, nuts, screens and burners.
