Shear Blades and Machine Knives find application in all
types of industries dealing with
steel/ non ferrous alloys, cellulose, fiber boards, paper and plastic etc.
Following parameters are of prime importance to Blades and Knives.
a. Hardness
b. Compression Strength
c. Wear Resistance
d. Long Cutting Life
e. Toughness
f. Shock Resistance
g. Close Tolerance
While selecting the most appropriate combination of the above parameters,
the manufacture
of shear blades needs to know the following details regarding the material
to be sheared.
1. The type of material i.e. whether it is ferrous or non ferrous.
2. The thickness of material.
3. The temperature of the material whether it is to be sheared hot or at
room
temperature.
4. Type of service continuous or intermittent.
5. The metallurgical properties of material including its tensile strength,
ultimate and
yield strength.
These details are extremely important to select suitable raw material and
heat treatment
process to achieve perfect combination of all the seven required qualities
of shear
blades and knives.
Shear Blades are essentially made out of various types of alloy steels and
each type of
alloy steel has its own characteristic dimensional changes in the heat
treatment.

Raw material before taking in to process should be tested in respect of
chemical
composition, metallographic analysis and ultrasonic testing. And in the
final stage of
inspection, blades & knives should be thoroughly checked in respect of
hardness and
dimensional accuracy.
