X |
|
his product has superior resistance to white rust, and can be oiled either separately or after phosphate treatment. |
Home appliance |
Phosphated |
P |
|
This type of product is appropriate for the coating steel without pre-treatment. Processability could be decreased under the decline of the friction coefficient. |
Home appliance, construction material |
