1.4401 316 Stainless Steel
Everything You Need to Know About Austenitic Stainless Steel X5CrNiMo17-12-2, 1.4401 316 According to EN 10088-1
What is 1.4401 316 Stainless Steel Quality?
1.4401 316 quality stainless steel is an austenitic stainless steel of high commercial importance. Stainless steel grade contains molybdenum in its chemical composition. This increases corrosion resistance. This is particularly important when it comes to crevice corrosion in chloride environments.
1.4401 316 quality stainless steel has the following features:
- Good corrosion resistance
- weldable
- Good resistance to oxidatio
Why use 1.4401 316 Stainless Steel?
1.4401 316 stainless steel grade has good machinability. While stainless steel quality cannot be hardened by heat treatment, it can be hardened by solution treatment. The good corrosion resistance exhibited by the 1.4401 316 stainless steel grade makes it marine grade stainless steel.
What is the chemical composition of 1.4401 316 stainless steel?
The chemical composition of 1.4401 316 stainless steel is as follows:
| 1.4401 316 steel chemical element | % present |
|---|---|
| Carbon (C) [Max] | 0.07% |
| Manganese (Mn) [Max] | 2.00% |
| Silicon (Si) [Max] | 1.00% |
| Chromium (Cr) | 16.5 to 18.5% |
| Nitrogen (N) [Max] | 0.11% |
| Molybdenum (Mo) [Max] | 2.00 – 2.50% |
| Nickel (Ni) | 10.0 to 13.0% |
| Phosphorus (P) [Max] | 0.045% |
| Sulphur (S) [Max] | 0.015% |
