Pros and cons of 304 and 316 stainless steel

Pros of 304 stainless steel

304 stainless steel is resistant to corrosion and intergranular corrosion. Strong corrosion resistance is found in oxidizing acids. These include concentrations below 65% of the boiling point for nitric. Good corrosion resistance is also found in most alkali solutions and organic and inorganic acids.

High-quality cold and hot forming processes and excellent performance. Can be processed plate, tube, line, strip, type products for manufacturing cold heading, deep punching, deep punching forming parts.

Better low-temperature performance. Under the condition of -180℃, the strength, elongation, and area reduction rate are good.

It has good weldability. We can often use welding methods before and without post-welding heat treatment.

Low price

Cons of 304 stainless steel

Large cross-sectional sizes of steel are sensitive to intergranular corrosion after welding.

Water containing C1 (including moist air) is susceptible to stress corrosion.

Low mechanical strength, such as poor cutting properties.

Pros of 316 stainless steel

Durability: 316 stainless steel is not only tough and versatile but at high temperatures can be maintained for a longer time than the 304 types.

Easy to process: 316 stainless steel has excellent weldability and machinability. Even at low temperatures, it also has excellent toughness. You can quickly process it into the products you want.

Corrosion resistance: 316 stainless steel added the chemical composition of molybdenum, making it more resistant to corrosion than 304 or other stainless steel alloys. 316’s resistance to corrosion makes it ideal for medical and pharmaceutical applications. This allows 316 steel to be used in highly acidic environments without causing any damage. It can also withstand strong disinfectants and the high temperatures needed to sterilize.

Cons of 316 stainless steel

High cost

Pros and Cons of Stainless 316

Pros: Stronger than 304 stainless. Cons: Requires the right tools to machine well.

Pros: Extremely corrosion resistant and performs well against pitting. Cons: More expensive than 304.

Pros: Resistant to salt water and caustic chemicals. Cons: Less formable and machinable than 304.
