What is the difference between 304 and 316 stainless steel fittings?

The key difference between 304 and 316 stainless steel that makes them different is the addition of molybdenum, an alloy that drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments. 316 stainless steel contains molybdenum, but 304 does not.

 

Is 304 or 316 stainless steel better?

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. When it comes to applications with chlorinated solutions or exposure to salt, grade 316 stainless steel is considered superior.

 

Can 304 and 316 stainless be used together?

While mixing these two grades can be practical in certain scenarios, such as using 304 for less critical components and 316 for those exposed to harsh conditions, careful attention must be paid to welding practices and potential corrosion issues at the joints.

 

Does 304 rust in water?

Corrosion resistance
It is considered resistant to pitting corrosion in water with up to about 400 mg/L chlorides at ambient temperatures, reducing to about 150 mg/L at 60 °C.

 

What is the equivalent material of 304 and stainless steel 304L?

Stainless steel 304 and stainless steel 304L are also known as 1.4301 and 1.4307
