316 and 316L stainless steels are molybdenum-containing grades. The molybdenum content in 316L stainless steel is slightly higher than that in 316 stainless steel. Due to the molybdenum in the steel, this grade offers superior overall performance compared to 310 and 304 stainless steels. Under high-temperature conditions, 316 stainless steel is widely used when the concentration is below 15% and above 85%. 316 stainless steel also boasts excellent chloride corrosion resistance, making it suitable for marine environments. 316L stainless steel's Carbon content: 0.03%, suitable for welding applications where annealing is not possible and required For high corrosion-resistant applications.
Corrosion-resistant
316 stainless steel offers superior corrosion resistance compared to 304 stainless steel, demonstrating excellent corrosion resistance during the pulp and paper production process. Additionally, 316 stainless steel is resistant to erosion from marine and corrosive industrial atmospheres.
Generally, there is little difference in the resistance to chemical corrosion between 304 and 316 stainless steel, although there are distinctions in certain specific media.
The initial stainless steel developed is grade 304. In certain conditions, this material is more susceptible to pitting corrosion. Adding an additional 2-3% molybdenum can reduce this sensitivity, giving rise to grade 316. Moreover, these extra molybdenum elements can also decrease certain thermal organic corruptions.
