410 410 Vs 316 Stainless Steel: Features And Advantages Comparison

The main differences between 410 stainless steel and 316 stainless steel are as follows:

I. Chemical composition

- The main components are iron, chromium and carbon. The chromium content is generally between 11.5% and 13.5%.

- The carbon content is relatively high, which makes 410 stainless steel have higher hardness and strength, but relatively weaker corrosion resistance.

- The main components include iron, chromium, nickel and molybdenum. The chromium content is about 16% - 18%, the nickel content is about 10% - 14%, and it contains 2% - 3% molybdenum.

- The presence of nickel and molybdenum greatly improves its corrosion resistance, especially in terms of resistance to chloride ion corrosion.

2.Physical properties

1. Hardness:

- 410 stainless steel is generally harder than 316 stainless steel. This makes 410 stainless steel more advantageous in some applications that require high hardness and wear resistance, such as tool manufacturing.

- 316 stainless steel is relatively soft, but its toughness is good.
2. Density:
- The density of the two is not much different, but due to the slight difference in composition, the density of 316 stainless steel may be slightly higher than that of 410 stainless steel.

3. Corrosion resistance
1. General corrosion:
- 316 stainless steel has excellent corrosion resistance and can maintain good stability in most environments. It can resist the erosion of a variety of corrosive media such as oxidation, acid, and alkali.
- 410 stainless steel has relatively weak corrosion resistance and is prone to rust in humid or corrosive environments.
2. Special corrosion:
- 316 stainless steel has strong resistance to chloride ion corrosion, so it is widely used in marine environments and chemical industries.
- 410 stainless steel is prone to pitting and crevice corrosion in chloride ion environments.

4.Application areas
1. 410 stainless steel:
- Commonly used in the manufacture of mechanical parts, knives, valves, etc. Due to its relatively low cost and high hardness, it is widely used in some industrial fields that do not require high corrosion resistance.
- It can also be used for some decorative applications, such as stainless steel accessories.
2. 316 stainless steel:
- It is mainly used in chemical industry, marine engineering, medical equipment, food processing and other fields with extremely high requirements for corrosion resistance.
