    Corrosion is a serious threat to the industrial cost of business. The importance in using the correct quality of fasteners such as banding, screws, and/or blind rivets plays a decisive role. In the United States, stainless steel fittings are mainly used with AISI 410 martensitic stainless steel self-drilling screws paired with a conventional neoprene or EPDM washer. Due to the low PRE value 10-12, the occurrence of corrosion is significantly more probable. GOEBEL Group’s newly developed screws and sealing CUP rivets with HNBR sealing washer are made from high-quality Duplex AISI 318LN (PRE 36) as well as Stainless steel AISI316L (PRE 23-28). The technical difference of the newly developed blue HNBR / duplex sealing washer proves itself in the considerably higher temperature resistance of about -30C to +160C. The resistance to weathering and aggressive compounds versus neoprene/EPDM (UV Radiation, Ozone, Mineral Oils and Acidic Gases) is higher as well.
