New ejector pins from Hasco America, Arden, N.C., are said to last longer under “dry-running” conditions than most others on the market. The Z412 pins are H11 steel whose surface is first nitrided to 68 Rc hardness. Then they receive two more coatings of molybdenum disulfide and a black oxide. Wear capabilities can be further enhanced with a specially formulated grease from Hasco. A very thin layer of grease is said to provide wear life similar to hard chrome The grease can withstand temperatures up to 2500 F.
