Corrosion Resistant Roller Chains Stainless Steel Chain Selection and Rated Working Loads Stainless steel chains may be selected by calculating chain tension and multiplying this calculated value by a set of factors given in the tables below. The factors will "derate" the chains based on impact conditions, operating temperatures, chain speed, corrosion circumstance, and the lubrication condition. To calculate chain tension please see page 41 "Slow Speed Selection" for drives and pages 104-105 for conveyors. The Rated Working load given in the chain dimensional tables should be greater than or equal to the calculated chain tension multiplied by the appropriate factors. Rated Working Load > T x SF x TF x SC x CF x LF Where: Rated Working Load is found on pages 59 - 61 T = Calculated Chain Tension SF = Service Factor TF = Temperature Factor SC = Speed Coef cient CF = Corrosion Factor LF = Lubrication Factor Service Factor Speed Coef cient Impact Loading SF Chain Spe e d (ft/min) SC Smooth Ope ration 1.0 0 - 50 1.0 Mode rate Impact 1.2 50 - 100 1.2 Large Impact Loads 1.5 100 - 150 1.4 150 - 250 1.6 Corrosion Factor Temperature Factor Te mpe rature (F) 304SS Me ga 600SS 6000SS 316SS Chain Corrosion Rating CF 1 1.00 -250 to -50 F 1.0 X 1.0 1.0 2 1.23 -50 to 140 F 1.0 1.0 1.0 1.0 3 1.44 140 to 300 F 1.0 1.0 1.2 1.0 4 Do Not Use 300 to 750 F 1.0 1.0 1.4 1.0 750 to 950 F 1.2 1.8 1.8 1.0 950 to 1100 F 1.5 X 2.1 1.2 1100 to 1300 F 1.8 X X 1.5 1300 to 1500 F X X X 2.0 X = Not Recommended See Corrosion Ratings on pages 64 - 65 Lubrication Factor LF Chain will be lubricate d 1.00 No lubrication 66 Lubrication 1.44
