Description
TECHNICAL DATA SHEET - DIN 1.2739
MATERIAL CATEGORY: Cr0.65 - Mo0.4 - V0.1 series steel
MATERIAL SPECIFICATIONS - BS 4659-1989
CHEMICAL COMPOSITIONS (WEIGHT - %)
C (％): 0.37 ~ 0.43
Si (％): 1.30 ~ 1.60
Mn (％): 0.30 ~ 0.90
P (％)≤: 0.030
S (％)≤: 0.025
Cr (%): 0.50 ~ 0.80
Ni (%): 0.70 ~ 1.00
Mo (%): 0.30 ~ 0.45
V (%): 0.07 ~ 0.12
HEAT TREATMENT PRACTICE AND HARDNESS
Annealed hardness, ≤ HB: 255
Annealing temperature /℃: 820 ~ 850
Cooling medium: Oil or Air
MELTING PROCESS
This alloy is generally smelt in Non-vacuum furnace + ESR, Electric Arc Furnace (EAF).
For a purpose of superior quality, it should be smelt via technology of Electroslag remelting or vacuum refining or by agreement.
PRODUCT PROFILE AND AVAILABLE FORMS
Round bar (Diameter): 5.5 to 430mm
Steel strip: THK0.15 ~ 2.50 X W8.0 ~ 610mm
Length: Fixed length or random length or based on the customer's special requirement.
Other different shapes based on OEM.
