WARTSILA AB FINLAND

Hello, for a ship gas pressure vessel reparation, we are very interesting if any one known a equivalent steel specified originally as:
RAEX 34 SLT
It seems that this specification is related with FINLAND standards.
These pressure vessels was bult by WARTSILA AB FINLAND.

This pressure vessel was built on 1985 and the design was made in 1982 or 1983.

Thanks in advance

You are correct in this being a Finnish steel. Produced by Rautaruukki (now Ruukki) http://www.ruukki.com/www/corporate.nsf?OpenDatabase&lang=1 RAEX is still one of their trade names. I am not sure about the exact designation you gave but 34S was classed as NV4-4 (low temperature carbon pressure vessel steel). I suggest you contact them via their home page to verify the other letters.
