AISI 5140 steel 1.7035 structural alloy steel
Description
5140 steel has good comprehensive mechanical properties and is one
of the most widely used steel types, used for manufacturing parts
of medium speed and medium load, such as machine tool gear, shaft,
worm, spline shaft and so on. The tensile strength, yield strength
and hardenability of 5140 alloy steel are higher than 1045 steel,
with higher fatigue strength and good toughness, normalizing or
tempering machinability are very good, annealing machinability is
also good, generally used after tempering treatment.
Form of Supply
AISI 5140 steel, we can supply the round bar, steel flat bar,
plate, hexagonal steel bar and steel square block. DIN W N-R 1.7035
steel Round bar can be sawn to your required lengths as one offs or
multiple cut pieces. 1.7035 alloy steel Rectangular pieces can be
sawn from flat bar or plate to your specific sizes. Ground tool
steel bar can be supplied, providing a quality precision finished
bar to tight tolerances.
