BS ISO 1835:2018 pdf free.Round steel short link chains for lifting purposes一Medium tolerance sling chains – Grade 4, stainless steel. The bases for calculation of the values for the dimensions listed in Table 1 are given in Annex A. The bases for calculation of the values for the mass per metre listed in Table B.1 are given in Annex B. The nominal diameter, dn, of the sling chain corresponds to the nominal diameter of the steel wire as presented in ISO 16124, or bar as presented in ISO 1035-1, from which the sling chain is made.Preferred nominal diameters are given in Table 1 column 1. Other nominal diameters may be used, provided the corresponding dimensions and tolerances are calculated in accordance with Annex A. The sling chain shall comply with the requirements of ISO 1834 as well as those of this document. 5.2 Material The steel used shall be austenitic stainless steels with molybdenum and shall be resistant against intergranular corrosion, for example the steel with the ISO name X6CrNiMoTi17-12-2 and the ISO number 4571-316-35-I according to ISO 15510. After solution annealing intergranular corrosion is unlikely at a service temperature of +400 °C and with an extra low carbon content…
