Applications 316L
Food processing, chemical and petrochemical equipment, brewery equipment, laboratory equipments, heat exchangers, chemical transportation containers.
Corrosion Resistance 316L
These grade exhibits excellent resistance to wide range of atmoshpere and corrosive media like petroleum, food, pharmaceutical, textile..etc.
Applications 316Ti
Its excellent for coastal architectual paneling and mining screens.
Corrosion Resistance 316Ti
316Ti has much better Corrossion resistence, having titanium the Stainless Steel is harder having super corrosive resistence.
Structural Fire Resistance 316Ti
For example, the titanium-stabilized Supra 316Ti/4571 has higher strength values at elevated temperatures than other stainless steep products.
Uniform Corrosion
Uniform corrosion is characterized by uniform attack on the steel surface in contact with a corrosive medium. The Corrosion resistance is generally considered good if the corrosion rate is less than 0.1 mm/year (0.004 in/year)
316L / 316Ti
have good resistance to uniform corrosion in many organic and inorganic chemicals. The addition of molybdenum enhances the alloy's corrosion resistance in many acidic environments. Austenitic stainless steels that contain molydenum are therefore sometimes denoted as "acid-proof grades."
Pitting and crevice corrosion
Pitting and crevice corrosion typically occur in acidic or neutral chloride solutions. This rangeof products provide excellent resistance to pitting and crevice corrosion. Resistance to these types of corrosion is enhanced by increasing the steel's chromium, molybdenum and nitrogen content. Nickel reduces the pitting propagation rate and faciities rate and facilities repassivation after pitting corrosion has started.
Atmospheric Corrosion
Austenitic stainless steels offer good resistance to atmospheric corrosion in applications where superficial surface staining from incipient pitting or crevice is usually undesirable. These products can noramally be used in moderately agressive industrial and coastal areas.
