Product Description
MOLYKOTE P-37 Antiseize Paste is a high-purity mineral-oil and solid-lubricant paste for bolted joints exposed to extreme heat. Its solid-lubricant system has a temperature resistance from -30 to 1,400 deg C, while the typical four-ball weld load is 5,500 N. Low seepage supports use where cleanliness is required, and sulfur content is limited to 250 ppm with total halogen content limited to 200 ppm. The paste is applied to cleaned, fully coated screws, nuts, and bolts made from heat-resistant alloys, including bolted joints used in gas and steam turbines.
Key features
- Extreme-Heat Threaded Joints: Solid-lubricant temperature resistance ranges from -30 to 1,400 deg C.
- Four-Ball Weld Load: Typical four-ball weld load is 5,500 N at 1,450 rpm for 1 minute.
- Controlled Trace Content: Total halogen content is 200 ppm maximum and sulfur content is 250 ppm maximum.
Applications
Screws, nuts, and bolts made from heat-resistant alloys, including high-temperature threaded connections in gas and steam turbines.
