DIN EN 10028-2 of High temperature Steel P235GH Round bar, Plate, P235GH Forging Bar Technical specifications Melting, ESR & VAR technique
DIN P235GH - MATERIAL DATA SHEET
MATERIAL CATEGORY - High temperature structural steel
TYPICAL APPLICATIONS
Mechanical gears, gear shaft, main axis, valve rod.
Mechanical parts - connecting rod, bolt and nut.
Multidiameter shaft. Pressure vessel.
PRODUCT DESCRIPTION
The alloy is usually produced by EAF /VD /LF followed by electroslag refining (ESR) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied bright in the softened condition.
Final heat treatment - heat treatment / QT
