Typical applications for EN31 steel include taps,
gauges, swaging dies, ejector pins, balls, and roller bearings. It is good
quality steel for wear-resisting machine parts and for press tools that do
not merit a more complex quality.
We have advanced precision machining gadgets, according to the requirements
of customers machining.
A good way to acquire maximum happiness with the person’s requirements.
Forging.
- Forge at 1000°/1051°C.
- Heat lightly, allowing sufficient time at the forging temperature for
the steel to be thoroughly soaked through.
- Re-heat as often as necessary to keep the temperature above 850°C.
- After forging cool very slowly, preferably in a furnace.
The hardening process of EN 31 Alloy steel.
- Heat uniformly to 800/821°C until heated through.
- Allow 30 minutes per inch of the ruling section and quench
immediately in oil.
Stress Relieving process of EN 31 Alloy steel.
- If machining operations have been heavy or if the tool has an
unbalanced section.
- Remove stresses before hardening by heating up to 700°C,
equalizing, then cooling slowly.
Annealing of the EN 31 Alloy steel.
- Heat uniformly to 801°C, equalize, then the furnace cools.
(Hardness about 230 Brinell).
MECHANICAL PROPERTIES.
- En31 alloy metallic mechanical properties, our manufacturing is
completely in step with the en31 alloy steel standards to satisfy the
en31 alloy steel mechanical performance.
- Also can be in line with the consumer request, to fulfill the
requirements of customers of en31 alloy steel mechanical properties.
