Our company has the ability to forge, quench and temper, process,
surface quench and carbonize high precision soft/ hard-surfaced
gear or gear shaft. The main specification is
withinΦ***0mm,
Mn≤*0mm.
Our company can produce ***0 tons gears and gear shafts annually,
and we also produce different products according to our customers'
requirements.
The main technical
parameters of gear
1. Standard of materials:
GB/T********9
2. The
grade of materials: *5, *0Cr, *0Cr , *5Cr Mo , *2Cr Mo, *0CrMnMo,
*0CrMnTi, *7CrNiMo6, *0CrNi2Mo, etc
3. Standard
of production: ISO********5
4. Smelting
method: electric arc furnace + refining furnace
5. Precision
accuracy: according to GB/T*******8 standard, within five
grade.
6. Hardness:
****0 HRC is the hardest; ****5 HRC is the average hardness; below
*8 HRC is the soft
7. Detection
methods and the implementation of standards
Samples are from
the same furnace
Tensile test is
done according to GB/T*******2 standard
Hardness test is
done according to GB/T**1.*****2 standard
8. Standard
of ultrasonic flaw detection
All forging pieces
must go through the JB/T********6 standard ultrasonic flaw
detection, grade two. If the forging pieces are within ***0 kgs,
they can reach the JB/T********6 standard, grade one
9. Magnetic
particle testing
Every product must
be tested after the surface quenching and machining.
Method: magnetic
particle testing
Satisfying
products: no crack, scab, white dot or fold. Repair welding is not
allowed.
Statistics above are for
reference. We can produce it according to different
requirements.
