304 vs 316: Which Stainless Steel Fits Your Needs?

 

How do their compositions differ?​

304 has 18% Cr, 8% Ni; 316 adds 2-3% molybdenum, boosting chloride resistance. 316 also has slightly more nickel for extra toughness.​

 

 

Which performs better in corrosive environments?​

316 excels in saltwater, chemicals, or marine settings thanks to molybdenum. 304 works well indoors or in mild outdoor conditions.​

 

 

Are there cost differences?​

316 is 20-30% pricier than 304 due to molybdenum and higher nickel. Choose 304 for budget projects with low corrosion risks.​

 

 

How do they handle high temperatures?​

Both tolerate heat, but 316 stays stable up to 1600°F (870°C), outperforming 304 in prolonged high-heat industrial tasks.​

 

 

Which is easier to fabricate?​

304 is slightly more ductile, making it easier to weld or form. 316 needs more precise welding techniques but remains workable.
