M30NW - 1.4472 - ASTM F1586
Description
The 1.4472 grade has superior corrosion resistance and mechanical properties to the 1.4441 (316LVM) grade. The mastery of its EAF/AOD production method followed by ESR remelting gives it a high level of cleanliness and homogeneity, which are essential to guarantee high fatigue resistance and quality processing.
Stainless has a number of qualified European sources in stock as well as different formats or product states to suit your processing needs. This product can also be made to measure or cut into slabs by our service centres.
Each material is delivered with its producer’s certificate of origin to guarantee total transparency and traceability.
Main applications
Due to its recognised biocompatibility in the medical field, the grade is mainly used in the manufacture of implants obtained by forging and/or machining. The material is available in the annealed state but also in the hardened state for smaller dimensions.
Metallurgy
The elaboration processes associated with the transformation processes make it possible to obtain a homogeneous microstructure with a fine grain of at least index 5
The microstructure consists of austenitic grains and does not show delta ferrite or Chi phase under standard observation conditions (X 100).
Machinability
Forgeability
The grade can be hot forged in the temperature range 1000/1150°C.
Polishability
The high level of inclusionary cleanliness and the homogeneity of the microstructure of this grade allows optimum polishing.
Typical Heat Treatments
Annealing at 1050-1080°C followed by rapid quenching can be carried out after forging to restore corrosion resistance, but no heat treatment is used to harden the grade.
Corrosion resistance
The grade is highly resistant to general and pitting corrosion due to its high molybdenum and nitrogen content combined with its low inclusion rate.
Standard Sizes
Round bars annealed, medium-hard or hard depending on the diameter – Surface ground or peeled.
