Martensitic 1.4418 X4CrNiMo16-5-1 Stainless Steel Round Bar
Grade EN 1.4418, DIN X4CrNiMo16-5-1 with low carbon content is popular with fabricators
as they are easier to weld than standard stainless martensitic steels.
Martensitic 1.4418, X4CrNiMo16-5-1 achieve a strength level comparable in some cases
to engineering steels, with a corrosion resistance that is close to that of well known stainless EN 1.4301, AISI 304.
| Grade | C | Cr | Ni | Mo |
| 1.4418, X4CrNiMo16-5-1 | 0.04 | 16.00 | 5.00 | 1.00 |
Stainless EN 1.4418 grade combines the following characteristics:
- Best pitting corrosion resistance of all martensitic stainless steel grades approaching that of 304
- Good strength. 700 MPa 0.2%PS, 900 MPa UTS at room temperature
- Excellent toughness, 80 J at room temperature. 40 J at -20°C
- Good weldability, especially for a martensitic stainless steel. No preheating required.
- Post weld tempering recommended
- Good wet abrasion resistance
EN 1.4418 stainless grade is designed to achieve a good balance of corrosion resistant and mechanical properties.
The chromium and molybdenum provides corrosion resistance.
The low carbon and increased nickel content provides a high strength martensitic structure but with good toughness.
There are also significant amounts of austenite and ferrite in the steel.
This structure also gives a much improved weldability compared to normal higher carbon martensitic grades.
It is proving to be a replacement for stainless grade 431 (1.4057, X17CrNi16-2) in some applications.
Applications which illustrate these features include:
Mining, cement plants, hydrofoil legs, anti-seismic applications, helicopter landing grids, penstocks, hydroelectric
turbine blades, hardboard and chipboard press plate, propeller shafting, pulp and paper.
