PRODUCT INFORMATION
Hasco Forge FO4-328B
OIL BASED FORGING LUBRICANT
Product Description
Hasco FO4-328 B is a heavy duty, lead free forging lubricant formulated with high levels of lubricity additives and a high viscosity to help improve die life and increase production on parts with difficult geometries. FO4-328B minimizes heavy die build up and produces low levels of smoke.
Applications
- FO4-328B is designed for the hot forging of aluminum alloys for the automotive and aerospace industries where die temperatures are typically between 670°F and 770°F.
- Certain applications and conditions may allow the product
to be used at temperatures outside of this range. - FO4-328B was designed for near-net aluminum applications, FO4-328B has been found to perform well in heavy-duty titanium applications.
- FO4-328B can be used as received or cut back with 20 – 30% with a light viscosity oil for lighter duty applications.
Features
- Excellent lubricity prevents excessive die wear and reduces scrap High flash point promotes fire safety.
- Minimizes heavy die build up
- Suspends graphite to reduce packing and lessens the need for agitation
- FO4-328B must be applied by swab or brush when used neat.
- If cut back with a light viscosity oil as described, high pressure spray equipment can be used.
- Agitation is recommended before and during use to ensure even distribution of the graphite.
