MATERIAL DATA SHEET - Grade 1.0425
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
MATERIAL SPECIFICATIONS - DIN EN 10028-2 (2003), DIN 17755 (1983)
PRODUCT PROFILE
Round bar / Wire rod (Diameter): 5.5mm to 800mm
Square bar / Flat bar: 3mm to 1000mm
Plate / Sheet steel / Steel strip: 0.1mm to 1000mm
Width: 8mm to 1000mm
Length: random length or based on the customer's special requirement.
Forged steel shape: stepped shafts with flanks / discs /tubes /slugs /donuts /cubes /other different shapes based on OEM.
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.
