EN 1.4313 ( DIN X3CrNiMo13-4 ) , F6NM , S41500 hot rolled stainless steel plate
W.-nr. 1.4313 ( DIN X3CrNiMo13-4 ) a 13% Cr-4% Ni-0.5% Mo a low–carbon martensitic stainless steel with basic corrosion resistance, good strength, good toughness and much better weldability than most martensitic grades of stainless steel.
Its nickel content, associated with low carbon ensures better weldability, ductility, impact and fatigue resistance than 13 Cr martensitic grades (410, 420).
The alloy has good corrosion resistance to fresh water and performs well in abrasive conditions.
It combines high mechanical properties, excellent toughness and weldability.
It is commonly used in turbines and flow control systems in the hydropower industries.

W.-nr. 1.4313 ( DIN X3CrNiMo13-4 ) grade is specially designed for applications requiring high strength, high toughness and medium corrosion resistance properties.
The chromium, nickel and molybdenum additions make the alloy resistant to corrosion in fresh water.
Typical applications are hydroelectric turbines and systems (blades, runners, gates, rings, shield plates,…), hydropter wings to fight cavitation by high speed water.
