PH 13-8Mo, 1.4534, X3CrNiMoAl13-8-2 - specification and application

13-8Mo is acid resistant special steel with martensitic structure, subjected to precipitation hardening, showing excellent mechanical properties - high hardness, strength and relatively high corrosion resistance, dynamic loads and cracking resistive.

Compared to other high alloyed grades exhibiting corrosion resistance, 13-8Mo steel has much more limited acceptability of sulfur and phosphorus in its chemical composition, which demonstrates a relatively difficult manufacturing process and high purity and quality of steel.

In aggressive environments (excluding moisture resistance) the species exhibits very good resistance to NaCl, Nitric Acid, and Sodium Hydroxide.

The PH13-8Mo is mainly used in the aerospace, nuclear, and petrochemical industries for parts and components subject to corrosion and heavy loads.
