WELDABILITY AND FRACTURE TOUGHNESS OF 5% NI STEEL PART 2: WIDE PLATE TESTING

This paper describes the results of wide plate tensile tests on 25 mm thick welded 5% Ni steel plates in double normalized and tempered condition. The test specimens were welded using the manual metal arc process with either a modified austenitic stainless steel electrode of a Ni-alloy electrode, or using the semiautomatic MIG-process with a Ni-alloy wire. The base metal and welded test specimens containing 6 to 30 mm long through-thickness notches were tested at temperatures ranging from -90 deg to -165 deg C. The test results indicate that welded 5% Ni-steel components can safely be used in the temperature range of -90 deg C to -165 deg C, whereby the lowest application temperature depends on the choice of the consumable. Indeed, a higher fracture toughness is obtained for specimens welded with Ni-alloy consumable than for specimens welded with a modified austenitic stainless steel consumable.
