DIN P250GH - 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, seamless pipe
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 black in the softened condition.
Final heat treatment - QT.
MATERIAL SPECIFICATIONS - DIN EN 10028-2 (2003), DIN 17755 (1983)
AVAILABLE SHAPES
Black bar /Flat bar / Square bar /Pipe, /Steel strip, /sheet
Bright - peeled + polishing, centerless grinding
Forged - ring, tube, pipe casing, discs, shaft
Alloy structural steels are widely used in the filed of ship, vehicle, airplane, guided missile, weapons, railway, bridges, pressure vessel, machine tools, mechanical components with a bigger sectional size and so on.
