Construction Machinery Attachments, good quality excavator bucket pins and bushings
1. High temperature resistance
The strength keeps stable up to 800℃ and it can even momentarily used at 1200℃.
2. Wear resistance
Due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a
CoCr alloy matrix, it has exceptional wear and galling resistance.
3. Corrosion resistance
This exellent and lovely property allows this kind of material parts to be used in oil&gas, slurry,
acid liquid and any other mediums.
4. Production process
Powder metallurgy pocess. It has better strength than casting parts, better granule structure and
avoiding the troubles caused by casting defects.
Production Process:
The raw materials
We strictly control the procurement of raw materials,Strict requirement for required steel must meet all property standards of 45# and 40Cr steel. Ensure quality at the source of production.
Roughing
Adopt double blanking of lathe, manual marking of production, multiple precision, running the material, ensure the follow-up production of material preparation on the premise of precision.
Lathe
The advanced digitized lathe, manually detects 100% of the product to ensure the standard of scientific data of subsequent processing
Drilling
To realize the normalization, standardization and conformity of drilling program data.
Heat treatment
In terms of product hardness, in order to guarantee product quality, there is no quality product with blasting lines or hidden cracks inside or outside. The hardness depth reaches 3-8mm, which makes it stronger and more durable.
Polishing
Manual supervision, measurement and adjustment are made for many times, so that the finished product can have a more refined appearance.
