Description

Material GX3CrNi13-4 is equivalent to trademark G-X 3 CrNi 13 4 acc. to SEW 685-89. It combines high strength and very good cryogenic properties. It is used at low temperatures in refrigerator construction up to approx. -120 °C. Material G-X 5 CrNi 13 4, material number 1.4313 is acc. to VdTÜV-material specification 452 applicable for pressure vessels acc. to TRB 100 (and AD-data sheets W5 and W10) from -120 to 20 °C. Further application for blade and guide wheels for pumps, compressors and turbines as well as for pump casings and machine components in hydraulic installations from -120 to 20 °C. Further application in the nuclear power engineering if the relevant specifications allow the application at -120 to 20 °C. The welding suitability of the steel cast is examined for the welding methods TIG-welding, metal arc welding and submerged welding. After the welding the material have to cool down under 80 deg. for an following heat-treatment. An double tempering or stress relieve annealing is possible. After the double tempering an decrease of the strength should considered. The cooling rate until below 300 °C should not exceed 80 K/h. By the welding in the production of thin-walled parts its possible to abandon the pre-heating, tempering or stress relieve annealing if appropriate verification was done.
