Our Damascus steel is hand-forged out of steel sheets of grade AISI 1075 and AISI 4340.
AISI 1075 is a high carbon steel that contains around 0.75% carbon. It is widely used to produce various types of springs and cutting tools.
AISI 4340 is a low carbon and high nickel steel alloy. It contains 1.65% – 2% Nickel, 0.7% - 0.9% Chromium and 0.3% to 0.4% Carbon.
Number of Layers:
Initially a stack of 11 sheets of AISI 1075 & AISI 4340 is formed. The stack is then heated and hammer forged. The heating and beating process is repeated 4 to 5 times to get 176 + layers of high quality Damascus steel.
Each blade is carefully heated to 1560 degree Fahrenheit, where after; it is oil quenched and tempered to achieve hardness above 58 to 60 on the Rockwell scale.
