DESIGN GUIDELINES FOR STAINLESS STEEL IN PIPING
Sulfuric acid Type 304 can be used at room temperature for concentrations over 80 . Type 316 can be used in contact with sulfuric acid up to 10 at termpera- tures up to 120ºF (50ºC) if the solutions are aerated the attack is greater in airfree solutions. Type 317 may be used at temperatures as high as 150ºF (65ºC) with up to 5 concentration.

• Sulfuric acid can create a highly flammable hydrogen gas if it is spilled on metals. • Skin and other bodily burns from sulfuric acid can be more serious than burns from other strong acids. Sulfuric acid dehydrates whatever it touches and the heat caused by that reaction with water can create secondary thermal damage.

Sulfuric Acid ENVIRONMENT SAFETY HEALTH AND QUALITY
Concentrated sulfuric acid is a strong oxidant and reacts violently with combustible and reducing materials. The substance is a strong acid it reacts violently with bases and is corrosive to most common metals forming a flammable/explosive hydrogen gas. Sulfuric acid reacts violently with water and organic materials with evolution of heat.
