Please find hereafter a selection of our grease fittings which we provide in the galvanized steel variant, in brass and also - as standard - in stainless steel.
The stainless steel grades we most commonly use are 1.4305 = 303 (V2A) and 1.4404 = 316L (V4A). Other models and materials can, of course, be supplied. Do ask us about the types wanted and sizes !
What is the origin of the "V2A steel" and "V4A steel" names?
Austenite is the name for a chrome/nickel steel which cannot be hardened by heat treatment and is, as a rule, non-magnetiseable.
In particular, more and more enquiries are being made about V4A stainless steel. What makes this material so special ?
