What Is Stainless Steel 316L Pipe Fittings?
The versatility of stainless steel grades is their ability to be modified to achieve certain characteristics. The modification procedure majorly focuses on the element that has been dealt with. In the case of Stainless Steel 316L Pipe Fittings, the change made by manufacturers is the content of carbon on its alloy. There are various types of A403 Gr WP316L fittings such as elbows, tees, reducers, stub end and pipe cap etc.
316L Equivalent Grades:
| STANDARD | WERKSTOFF NR. | UNS | JIS | BS | GOST | AFNOR | EN |
| WP316L | 1.4404 | S31603 | SUS 316L | 316S11 / 316S13 | 03Ch17N14M3 / 03Ch17N14M2 | Z3CND17‐11‐02 / Z3CND18‐14‐03 | X2CrNiMo17-12-2 / X2CrNiMo18-14-3 |
Chemical Composition of 316L:
| GRADE | | C | MN | SI | P | S | CR | MO | NI | N |
| 316L | Min | – | – | – | – | – | 16.0 | 2.00 | 10.0 | – |
| Max | 0.03 | 2.0 | 0.75 | 0.045 | 0.03 | 18.0 | 3.00 | 14.0 | 0.10 |
Stainless Steel A403 WP316L contains higher chromium and low carbon content.
Lower carbon means less chromium carbide precipitation due to welding. This steel type contains as low as 0.03% of carbon content and thus reduces its susceptibility to intergranular corrosion. This kind of steel can be continuously exposed to temperatures of about 1500°F without appreciable scaling.
