PH 13-8 Mo (1.4534) Stainless Steel -> AMS 5629, AMS 2300, AMS 2315

PH 13-8 Mo or 13-8 Mo stainless steel is a PH (precipitation hardened) stainless steel grade which is also known as 1.4534 grade. This grade is written as 1.4534 or X3CrNiMoAl13-8-2 according to EN norm and it is written as UNS S13800 according to UNS norm. PH 13-8 Mo stainless steel grade is used mainly on aircraft landing parts, landing gears and other aircraft parts. This grade is better then 17-4 PH and 15-5 PH in many applications. PH 13-8 Mo is hard to produce and vacuum melting is required. Because of this production method, this grade is really expencive. PH 13-8 Mo is usually produced according to AMS 5629 standart. 1.4534 grade stainless steel is good for corrosion resistance and this grade have very strong mechanical properties. Yield strenght of this grade is about 1400 MPA and corrosion resistance of this grade is better then 316L in many applications. PH 13-8 Mo is magnetic and it is not so easy to machine this grade. Here are some of the other details about PH 13-8 Mo grade material.
