Hardness after annealing ≤HBW : 240
Quenching temperature ℃ ±10℃ : 950 ~ 980
Cooling medium: Oi, air
Tempering temperature ℃ ±10℃ : 960 (Austenitizing temperature)
Hardness value after tempering /≥ HRC: 325HB Max.
MELTING PROCESS
This alloy is generally smelt in electric arc furnace EAF LF VD / BEF + Electroslag remelting (ESR).
For a purpose of higher quality, it should be smelt via technology of vacuum refining.
TYPICAL APPLICATIONS
Alloy tool steel is widely used to produce the cutting tool, cold / heat distortion mould and measuring implements, and further to manufacture the piston, valve, valve seat of fuel pump of diesel engine.
Cutlery for medical equipments.
Cutting tools, Mechanical parts, Air hammer tools, Piercing tools.
PROFILE AND DIMENSIONS
Round bar & Dics (diameter): 5.5mm to 650mm
Square bar / Flat bar: 10mm to 800mm
Length: random length, fixed length or based on the customer's special requirement.
Heavy/middle plate via hot rolled: T60 - 400mm X W60 - 1000mm X L1000 - 5000mm
Forging piece: stepped shafts, and other different shapes based on OEM.
