Our high-precision CNC connecting pins, custom-forged and turned
from 42CrMo steel, represent the apex of manufacturing excellence.
These precision-crafted pins are designed to meet the exacting
demands of various industrial applications, ensuring reliable and
efficient connections.
The use of 42CrMo steel, a high-strength alloy, guarantees
durability and resilience, even under extreme conditions. This
material's exceptional mechanical properties allow our connecting
pins to withstand heavy loads and maintain their integrity over
time.
The custom forging process ensures that the pins are shaped to
precise specifications, ensuring a perfect fit for the intended
application. The turning process further enhances the pins'
accuracy, ensuring smooth surfaces and tight tolerances.
Our advanced CNC machinery and skilled operators work in tandem to
achieve the highest levels of precision and repeatability. This
ensures that every pin we produce meets or exceeds the strictest
quality standards, delivering optimal performance and reliability.
Wh you need a single pin or a large batch, we have the capability
to produce high-precision CNC connecting pins with custom forging
and turning using 42CrMo steel. Our commitment to excellence and
customer satisfaction makes us the ideal choice for all your
precision machining needs.

42CrMo steel is ultra-high strength steel with high strength and
toughness, good hardenability, no obvious temper brittleness, high
fatigue limit and resistance to multiple impacts after quenching
and tempering, good low temperature impact toughness. The steel is
suitable for the manufacture of large and medium-sized plastic
molds that require a certain strength and toughness.
Applicable scope:
High strength, high hardenability, good toughness, low deformation
during quenching, high creep strength and long-lasting strength at
high temperatures. Forgings requiring higher strength and larger
quenching section than 35CrMo steel, such as locomotive traction
Gears, supercharger gears, pressure vessels, rear axles, for load,
for, for, for, and for, and, and
Material Characteristics:
42CrMo steel has high strength and toughness, good hardenability,
no obvious temper brittleness, small deformation during quenching,
high fatigue limit and resistance to multiple impacts after
quenching and tempering, good low temperature impact toughness,
High creep strength and long-lasting strength at high temperatures.
The steel usually has a quenched surface after quenching and
tempering as a heat treatment scheme.
