2205 in chromium, molybdenum and nitrogen content of corrosive and acidic solution, corrosion rust and cracks with a strong resistance. In sulfuric acid solution containing 2000ppm chloride medium corrosion curves 4 mpy (0.1 mm / yr) Resistance to stress corrosion the duplex microstructure of stainless steel cufflinks help to improve its corrosion resistance to stress cracks. A certain temperature, pressure, oxygen and chloride in the presence of chloride stress corrosion phenomena occur. The cufflinksare not high grade but very unique and chic. Because these conditions should not control. 304L, 316L and 317L use is limited in this regard.
2205 alloy, high strength and corrosion resistance to provide excellent resistance to corrosion fatigue strength. Mainly used in the environment has a strong corrosive. The AvestaPolarit erosion battery measured in 1M NaCl erosion of the critical temperature. 2205 The chemical composition after 1040 ° / 1080 ° C solid solution annealing treatment, the ideal microscopic structure of 50 α / 50 of γ. If the heat treatment temperature above 2000 ° F may cause the increase of the ferrite component. Mens cufflinks are not necessarily expensive, but must be unique and have personality. Like other duplex stainless steel cufflinks, 2205 is vulnerable to the impact of intermetallic phase precipitation. Precipitation of intermetallic phases between 1300 ° F and 1800 ° F, the temperature of 1600 ° F, precipitation fastest.
Therefore, we need the 2205 test, the test reference ASTM A 923. We recommend forming should be below 600 ° F temperature. During the hot forming process, the entire workpiece should be the overall heat in the 1750 ° F to 2250 ° F temperature range, 2205 is very soft at this temperature. If the temperature is too high, the 2205 alloy to hot tearing. Below this temperature, the austenite will break. Lower than 1700 ° F, due to the influence of temperature and deformation, meet soon to form intermetallic. There are more and more opportunities for the modern men like Mr. Ma to attend various types of formal occasions wearing cufflinks. Hot forming is done, should prompt a minimum temperature of 1900 ° F anneal and quench to restore phase balance, toughness and corrosion resistance. We do not recommend for stress relieving, but if you have to do it, the material should be a minimum temperature of 1900 ° F anneal, and then rapidly cooled by water quenching.
2205 alloy cutting and cold forming. However, due to the 2205 high strength and hardness, it is more than the austenitic steel the need for cold forming, also because of its high strength, taking fully into account springback. 2205 alloy should be a minimum of 1900 ° F temperature annealing, and then rapidly cooled by water quenching. Along with this are the rising and strict requirements for the cufflinks. This treatment applies to both solution annealing and stress relieving. Stress relieving treatments at temperatures below 1900 ° F, easily lead to the precipitation of harmful metals or non-metallic phase.
In the high-speed machine tool, feed rate and cutting speed of 2205 alloy and 316L is the same. When carbide tooling, cutting speed is reduced by about 20% compared to 316L, the performance of machinery and equipment and their components plays a key role in this. Welding of 2205 alloy is very good. Part of the 2205 alloy to achieve the performance of the weld metal and heat deterioration remains of the base metal corrosion resistance, strength and toughness. Welding of 2205 is not difficult, but need to design welding procedures, so that welding can maintain good phase equilibrium, to avoid the precipitation of harmful metals or nonmetallic phases. mens cufflinks seem to be one of the essential accessories.
