OKS 210 - High-Temperature Screw Paste, for high-alloy steels

Areas of application

Assembly lubrication of high-alloy bolted connections exposed to high temperatures, or corrosive or chemically aggressive influences
Lubrication of materials prone to galling or corroding, such as V2A, V4A and other high-alloy steels
Such as those on gas and steam turbines in the power station sector
In combustion engines
Screwed connections on pipe fittings, flange joints and fittings in superheated steam lines
Screwed connections on exhaust pipes, in combustion chambers and similar

Advantages and benefits

Minimises chromium(VI) forming on steels with a chromium content when exposed to high temperatures
Metal-free (as per recipe)
Less than 500 ppm of flourides, chlorides and sulphides
Prevents galling of high-alloy bolted connections during assembly
Allows non-destructive dismantling after a long period of use and under aggressive operating conditions
Good water resistance
Wide operating temperature range
Constant coefficient of friction
MOSH/MOAH-free (as per recipe)
NSF H1 registered

Technical specifications

lower operating temperature: -40 °C
upper operating temperature: 1000 °C (separation)
breakaway torque: < 2.5 x tightening torque (M10 A4, 40 Nm, 400 °C, 100 h)
UFI: 5XJC-G0H8-E00X-R928

Applications

For best adhesion, clean the threads and sliding surfaces from dirt and other lubricants. Best way is to clean mechanically first and then with OKS 2610 or OKS 2611 universal cleaner. Apply paste evenly in sufficient amount onto head/nut support and thread or onto the sliding areas with brush, spatula, etc. Paste also takes over sealing properties. Do not use paste instead of grease and mix with appropriate lubricants only.
