316 Stainless Steel Alloy

316 Stainless Steel Alloy

316 Stainless Steel Alloy, a molybdenum bearing steel, can resist pitting with solutions that contain chlorides and halides. In extreme temperatures, this stainless steel series alloy has tensile, creep, and stress rupture strength. This durable alloy is also resistant to dilute solutions of 1-5% of sulfuric acid, as high as 120 degrees Fahrenheit.

When exposed to temperatures ranging from 800-1500 degrees Fahrenheit, 316 Stainless Steel is prone to carbon precipitation; as a result, the alloy is also prone to intergranular corrosion in the as-welded state. After the welding process, annealing will help improve the alloy’s resistance to corrosion.

Type 316L has the same composition as regular 316 Stainless Steel, with the exception of the carbon content, which is below 0.03%. Physical properties and corrosion resistance are similar between both types; on the other hand, 316L provides protection against intergranular corrosion in the welded condition. When in temperatures between 800-1500 degrees Fahrenheit, this alloy also can resist intergranular corrosion.

It is advisable to apply 316L when presence in the carbide precipitation range cannot be avoided or when annealing after the welding process is impractical.  When exposed to the carbide precipitation range for too long, the material may become damaged and intergranular attack may be more likely to take place.  Under the previous circumstances, it is recommended to use stabilized alloys such as 321, 347, or 348.

Scaling resistance in continuous service methods allows for a maximum temperature of 1650 degrees Fahrenheit, while intermittent service allows for 1500 degrees Fahrenheit. Both 316 type alloys are typically used in bellows, instrument diaphragms, filters, and more.
