RS-2 alloy has the following characteristics:
This is a sulfuric acid-resistant austenitic stainless steel with lower alloy content and better corrosion resistance.
Applications of RS-2:
The plate heat exchanger, wire mesh defoamer and acid-resistant pump castings made of this material are widely used in sulphuric acid, phosphoric acid and phosphate fertilizer industries.
