Stainless Steel Bolts and Fasteners
Stainless Steel Bolting
All grades of austenitic (A1-A5) and martensitic (C1-C4) stainless steel bolting can be produced, from class 50 through to 100.
When compared to Carbon steel, the additional Chromium content in stainless steel helps to protect against corrosion.
Â
Properties and Grades of Stainless Steel
Stainless steel fasteners are available in several grades.
Â
304 (A2 or B8) stainless is one of the most popular grades of stainless steel and is classed as commercial grade stainless. With a chemical composition of 18% chromium and 8% nickel, the high chromium percentage offers excellent corrosion resistance.
Â
316 (A4 or B8M) takes things further. The addition of molybdenum provides further resistance against corrosion. 316 stainless also tends to include more nickel.
Â
Although the mechanical properties of grades 304 and 316 stainless steel are broadly comparable, the addition of molybdenum alongside increased nickel content in 316 stainless makes for greater resistance to chemicals including acids and chlorides. This makes 316 ideal for chemical, medical and marine applications.
Â
We use the following specifications and grades of stainless steel in the manufacture of our bolts and fasteners.
| Materials | Grades | |
|---|---|---|
| Stainless Steel | 303, 304, 310, 316, 317, 321, 347, 410, 420, 431, 904L | A2-50, A2-70, A2-80, A4-50, A4-70, A4-80, A4-100, A193 / A320 B8, B8M |

Industries
Applications
Stainless steel fasteners and bolts are in use across a wide array of industries worldwide.
Stainless Steel fasteners are extremely versatile and have many useful applications:
Commercial grade A2 stainless is generally used in the following environments:
- Household
- Dairy
- Food production
Due to the increased corrosion resistance from the addition of Molybdenum, 316 stainless steel fasteners are commonly used in the following industries:
- Chemical processing
- Medical
- Marine
- oil and gas components
- hot water tanks
- manifolds
- heat exchangers
- connectors
- water heaters
- pipework and flanges
