304 Stainless Steel vs 316
304 stainless steel is widely used, offering excellent corrosion resistance and heat resistance. It is also readily welded. Another variation, 304L, is extra low carbon and prevents harmful carbide precipitation during welding. Both grades offer excellent corrosion resistance, but 304L has slightly lower mechanical properties. 304 Stainless Steel vs 316, Which is better? In some applications, 316 steel is a better choice, as it offers better heat and oxidation resistance.
304 Stainless Steel vs 316 Chemical Composition
304 stainless steel and 316 stainless steel are similar in their chemical composition, with the difference being in their nickel and molybdenum content. Both contain chromium, which makes them corrosion-resistant. Both types are highly tensile, but 316 has a longer life expectancy.
Stainless steel grade 316 is more resistant to corrosive substances than 304, which makes it more suitable for marine equipment. However, 304 stainless steel is cheaper and more practical in many applications. The two grades are interchangeable. As long as you know the temperature you plan to use your product, you can use either one.
Grade 316 is a higher quality steel, containing higher concentrations of chromium and nickel. It also contains trace amounts of molybdenum, which gives it a higher level of corrosion resistance. 316 is also more expensive per ounce because of its higher nickel and molybdenum content.
