Cold Drawn Stainless Steel Wire In Coil or Ground Round Bar EN 1.4031 DIN X39Cr13
EN 1.4031, DIN X39Cr13, 13% chromium martensitic stainless steel
| Grade | C | Si | Mn | Cr |
| 1.4031, X39Cr13 | 0.36~0.42 | 1.00 max | 1.00 max | 12.50~14.50 |
Type 1.4031 is used in the quenched and tempered condition in a host of constructional applications
where moderate corrosion and abrasion resistance is required. Due to its higher carbon content,
1.4031 is more hardenable than 1.4028 and as such is suitable for use as a blade material.
As for other martensitic grades, optimal corrosion resistance is attained when the steel is in the
hardened condition and the surface is finely ground or polished.
| General properties |
| corrosion resistance | average |
| mechanical properities | very good |
| foreability | good |
| weldability | with care, not good |
| machinability | average |
1.4031 can be soft annealed by holding at a temperature in the range 750 °C to 850 °C followed
by slow cooling in an oven or air. In this condition, the following mechanical properties can be
expected:
