ISO DIS 1835

Description / Abstract: This International Standard specifies the requirements for medium tolerance sling chains of grade 4 from stainless steel for use preferably in chain slings of grade 4 from stainless steel or for other lifting purposes.

The range of nominal diameter d_n covered by this International Standard is from 4 mm to 22 mm.

These sling chains are round steel short link chains with a nominal pitch pn = 3×d_n electrically welded, heat treated and tested. They are for use in the temperature range –100 °C to +400 °C.

The sling chain is solution-annealed in the finished condition and can therefore be used without restrictions with regard to the corrosion resistance of the steels according to clause 5.2.

NOTE 1 Higher grades of stainless steel chains are achieved by cold drawing of the wire prior to the chain manufacturing. Therefore, solution annealing is not possible without reduction of strength. The weld seam, in particular, represents a critical area with regard to the corrosion resistance.

NOTE 2 Resistance butt welding and flash welding are listed in ISO 4063.

They comply with the general conditions of acceptance of ISO 1834.
