Hastelloy Alloy C-4 Plate

1, Hastelloy from Hastelloy, began Hastelloy B alloy, used in aircraft rocket nozzles; subsequent Hastelloy C alloy in the chemical industry, petrochemicals, nuclear energy industry and the pharmaceutical industry to be applied and promoted; followed by Hastelloy X alloy showed excellent high temperature resistance, along with the rapid growth of the jet aircraft industry.
2, due to the early Hastelloy B, Hastelloy C, as well as Hastelloy X alloys need to be welded solid solution treatment, otherwise, the corrosion resistance of the weld heat-affected zone will be greatly reduced; so the above alloys have been gradually improved or no longer used;
3, affect the welding performance of the above materials is the key reason for C, Si content, due to the emergence of refining technology and improve, Hastelloy welding problems can be improved, so there are a lot of promotion of the use of improved Hastelloy B series, Hastelloy C series alloys, etc., it is very regrettable that a lot of production and promotion of Hastelloy alloys, but instead of Hastelloy alloys will be replaced by a Hastelloy alloys to improve the Hastelloy alloys later on. Not only does not reduce C, Si content, but back to the previous high Si, high C content; special steel business promotion is a long way to go.
4, reducing medium resistant Hastelloy B series alloys in the Hastelloy B grades on the basis of improvement, improvement focus including very low C, Si content to improve the performance of the welding region, further alloying ideas, the application of the idea of purification of the steel, etc., so that the Hastelloy B series Hastelloy B-2, Hastelloy B-3, Hastelloy B-4 alloys; of which the Hastelloy B-2 alloys to a certain extent to solve the welding Regional performance issues; Hastelloy B-3 to solve the Hastelloy B-2 easily precipitated Ni-Mo precipitation hardening shortcomings, greatly improving the hot and cold working performance.
5, reducing environment application materials Hashi B series improvement process; in the redox composite environment Hashi C series alloys are also continuing to improve, which Hashi C276 alloy due to lower C, Si content and to a certain extent improved the welding region performance problems, but still not very satisfactory, plus processing performance did not increase the improvement; and Hashi C22 materials more thoroughly solve the corrosion resistance of the welded areas Problems, processing performance problems, more mainly in the material cost does not increase on the basis of the solution, so Hashi C22 material is Hashi C series of the most cost-effective materials, the future will certainly be more high-volume applications; and the newly developed Hashi C2000 material in the alloy added Cu, which expands the Hashi C alloys in the corrosive ability in the reductive environment, for safer use, for a higher life expectancy of the equipment requirements, and for new process trials.
Hastelloy is ultra-low carbon type, Ni, Mo, Cr series of nickel-based, corrosion-resistant, high-temperature materials Hastelloy (Hastelloy), because it has excellent high-temperature resistance, oxidation resistance, weld-affected zone corrosion resistance, with very good long-term thermal stability and processability, in the agrochemical, nuclear facilities, biopharmaceuticals and other harsh industrial environments are used. It also has excellent resistance to corrosion, homogeneous corrosion and intergranular corrosion in wet oxygen, sulfite, acetic acid, formic acid and strong oxidising salts of the medium, so it is also widely used in the chemical industry. The electrical conductivity and thermal conductivity of Hop Hastelloy gold is much lower than that of mild steel, while the resistivity and expansion rate are much higher than that of mild steel, the molten pool has poor mobility, poor wettability, low penetration, and shallow melting depth.
