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.

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.
