Stainless Steel Grade 304 Vs 316

As part of the five families of stainless steel 304 stainless steel and 316 stainless steel are austenitic grades that contain high levels of chromium and nickel.

Stainless steel grade 304 vs 316.

Stainless steel types can be found here. This has the following impact. 304 vs 316 stainless steel. The addition of molybdenum provides pitting resistance in phosphoric acid acetic acid and dilute chloride solutions and provides corrosion resistance in sulfurous acid.

316 stainless steel for a material to be considered stainless steel at least 10 5 of the make up must be chromium. The key difference between stainless steel grades 304 and 316 is the addition of molybdenum an alloy that drastically enhances corrosion resistance especially for more saline or chloride exposed environments. When it comes to applications with chlorinated solutions or exposure to salt grade 316 stainless steel is considered superior. Stainless steel equipment can be made out of all three types of stainless steel.

Typically 2 to 3 percent. Stainless 304 usually consists of 18 chromium and 8 nickel. Similar to 304 grade 316 stainless steel has high amounts of chromium and nickel. Additional alloys typically include nickel titanium aluminum copper nitrogen phosphorous selenium and molybdenum.

Though the stainless steel 304 alloy has a higher melting point grade 316 has a better resistance to chemicals and chlorides like salt than grade 304 stainless steel. Chromium increases tensile strength hardness hardenability toughness resistance to wear and abrasion resistance to corrosion and scaling at elevated temperatures. Stainless 316 is made up of 16 chromium 10 nickel and 2 molybdenum. The two most common austenitic stainless steel grades are 304 and 316.

Choose the correct grade of stainless steel to meet the environment and application. 316 also contains silicon manganese and carbon with the majority of the composition being iron. A major difference between 304 and 316 stainless steel is the chemical composition with 316 containing a significant amount of molybdenum. Outwardly 304 stainless steel and 316 stainless steel look very similar.

The main difference between 304 vs 316 stainless steel is the composition and corrosion resistance ss304 doesn t contain molybdenum while ss316 contains 2 3 molybdenum. 316 304 or 430. The two steel grades are comparable in appearance chemical makeup and characteristics. Stainless 316 contains more nickel than stainless 304 while 304 contains more chromium than 316.

The 304 stainless steel fasteners series is made up of approximately 18 chromium and 8 nickel 18 8. Last updated on july 1 2020 by marsh fasteners. Each of these stainless steel grades will resists corrosion are quite durable and are easily formed and fabricated.
