When they are required, the following ductility tests shall be carried out: reverse bending test, tensile strength test

40、 on knotted wire or wrapping test. The parties shall agree upon the required ductility tests and on the minimum required results. 5.4 Magnetic permeability When the grade X4CrNi18-12 (1.4303) is required with a very low permeability (non-magnetic), the magnetic permeability shall be less than 1,05.

41、The grade X4CrNiMo17-12-2 (1.4401) may also be requested with low permeability.

42、e The diameter of the wire shall be measured with a micrometer with an accuracy of at least 0,001 mm for dimensions below 0,65 mm. For larger wire, an accuracy of 0,01 mm is acceptable. 6.3 Tensile test The tensile test shall be carried out in accordance with EN 10264-1. 6.4 Reverse bend test The re

43、verse bend test shall be carried out in accordance with EN 10218-1. 6.5 Wrapping test When coiled for 8 turns around a mandrel of equal diameter to the wire, the wire shall show no signs of breaking; the test shall be carried out in accordance with EN 10218-1.

44、 6.6 Tensile test on knotted wire For diameters 0,50 mm, the tensile test on knotted wire shall be carried out in accordance with EN 10218-1. The strength is then measured on a wire in which 1 simple knot has been made. This strength is expressed as a percentage of the tensile strength of the unknot

45、ted wire. 6.7 Magnetic permeability Magnetic permeability shall be measured in accordance with ASTM A342 method 4 in a field of 500 to 1 000 Oersted.
