1.0425
P265GH
The 1.0425 (P265GH) is a pressure vessel steel: tough, easy to weld, and approved for internal pressure per DIN EN 10028. The "P" stands for Pressure, the number for the [[glossary:streckgrenze|yield strength]]. Typical analysis: 0.16 % C, 1 % Mn, 0.25 % Si. For higher [[glossary:verschleissschutz|wear protection]], three hard-facing options are available: S Fe 1 (martensitic, approx. 300–400 HB, machinable), S Fe 2 (wear-resistant and tough, approx. 50–55 HRC, conditionally machinable) and S Fe 15 ([[glossary:karbid|carbide]]-rich, approx. 55–65+ HRC, not machinable).
