The stainless steel fasteners are widely used in the industrial fastener industry due to their high strength, corrosion resistance and durability. There are various grades available; SS 304 and SS 316 are the two most popular fasteners for use in different industry segments, including construction, marine, chemical processing, oil & gas and food processing.
There are different types of fasteners, however, many buyers and engineers often ask; what is the difference between SS 304 and SS 316 fasteners? By knowing their properties, composition and uses, industries can choose the material to ensure long-term performance and cost effectiveness.
Jaysteelcorporation is one of the leading trusted SS 316 fasteners suppliers and SS 304 fasteners Exporters in India that offer high-quality stainless steel fasteners that adhere to international industrial standards.
It is important to understand stainless steel fasteners.Knowing about stainless steel fasteners is essential.
Bolts, nuts, screws, washers, threaded rods and studs are all fasteners made of stainless steel alloys. These fasteners are preferred due to the following advantages:
- High corrosion resistance
- Excellent tensile strength
- Long service life
- Attractive finish
- Heat resistant and chemical resistant.
Of all the stainless steel grades, SS 304 and SS 316 are the most popular grades because of their versatility and reliability.
What is SS 304 Fasteners?
The fasteners made of SS 304 are made from austenitic stainless steel, which is a chromium and nickel alloy. This grade is frequently referred to as the 18/8 stainless steel grade, as it contains around:
- 18% Chromium
- 8% Nickel
SS 304 fasteners are also very corrosion resistant and have good mechanical properties, making them widely used in general industrial applications.
Jaysteelcorporation is a prominent SS 304 fasteners Exporter in India that provides superior grade SS 304 bolts, nuts, washers and SS 304 screws to several industry applications.
Key Features of SS 304 Fasteners
- Resists oxidation very well
- Excellent formability and weldability
- Strong mechanical properties
- Cost-effective solution
- Can be used in mild indoor and outdoor conditions.
What are SS 316 Fasteners?
SS 316 fasteners are a better grade of SS 304 fasteners. The main difference lies in the chemical composition which includes molybdenum.
Typical composition includes:
- 16–18% Chromium
- 10–14% Nickel
- 2–3% Molybdenum
Mo is added for a substantial increase in chlorides, salt water and severe chemical resistance.
As a trustworthy SS 316 fasteners supplier, Jaysteelcorporation supplies high quality stainless steel fasteners that are highly effective in corrosive and marine applications.
Key Features of SS 316 Fasteners.
- Superior corrosion resistance
- Very resistant to pitting and crevice corrosion.
- Improved performance in chlorides
- Excellent resistance to marine and chemical wear.
- Appropriate for high temperature uses
Main Difference Between SS 304 and SS 316 Fasteners:
1. Chemical Composition
The main difference is that molybdenum is present in the material of SS 316.
SS 304 Composition
- Chromium: 18%
- Nickel: 8%
- No molybdenum
- SS 316 Composition
- Chromium: 16–18%
- Nickel: 10–14%
- Molybdenum: 2–3%
Molybdenum enhances corrosion resistance, especially against chlorides and industrial chemicals.
2. Corrosion Resistance
One of the most critical parameters to consider when choosing fasteners is corrosion resistance.
- SS 304 Fasteners
Ss 304 fasteners are highly resistant to moisture, oxidation and mild chemicals. They can however corrode to rust or pit in saline or chloride laden atmospheres.
- SS 316 Fasteners
Molybdenum enhances resistance to chloride corrosion, which accounts for the significantly better performance of SS 316 fasteners in marine, coastal and chemical environments.
This is the reason why industries that operate close to seawater prefer to obtain products from an experienced supplier of SS 316 fasteners.
3. Strength and Durability:
Excellent strength and durability in both grades.
SS 304
- High tensile strength
- Good impact resistance
- Able to be used in general industry applications.
- SS 316
- Somewhat stronger at higher temperatures
- Improved corrosion resistance in the long term
- Improved stress corrosion cracking (SCC) resistance
- SS 316 is typically used for challenging applications.
4. Temperature Resistance
Due to their excellent high-temperature properties, both SS 304 and SS 316 fasteners are suitable for high-temperature use.
However:
- For higher temperatures, SS 316 fasteners are better at resisting “creep”.
- Fasteners made from SS 304 can be used for moderate heat applications.
- SS 316 is generally used in industries that use heat exchangers, boilers and chemical plants.
5. Cost Difference
Another critical part to material selection is the cost.
SS 304 Fasteners
- More affordable
- Widely available
- Affordable in the regular industrial applications.
- SS 316 Fasteners
- These have higher cost because of the molybdenum content.
- High performance investment in severe conditions.
- While more costly, SS 316 fasteners in corrosive applications provide lower maintenance and replacement expenses.

Which is Better: SS 304 or SS 316 Fasteners?
This is subjective and depends on the needs of the application.
If you choose SS 304 Fasteners, you should consider the following:
- A cost-effective solution is required.
- The temperature of the environment is mild or non-corrosive.
- The application is for indoor or general purpose use.
- Have SS 316 Fasteners If:
- It is in a salt water or chlorides environment.
- High exposure to chemicals
- The long term corrosion resistance is needed
When using from an economic point of view, the marine and chemical industries would definitely be better served with the SS 316 option, even though it is more expensive.
