Nitrogen stainless steel plate 2205 alloy is nickel alloy consisting of duplex stainless steel. It has high strength, good impact toughness and good overall and local stress corrosion resistance, the advantage of duplex stainless steel, corrosion resistant properties of 2205 in most circumstances is better than 316 l and 317 l.
2205 alloy stainless steel and 316 l and 317 l austenitic x70 line pipe stainless steel, compared to 2205 alloy on the pitting corrosion and crevice corrosion resistance is superior, it has the very high corrosion resistance, compared with austenitic, its lower thermal expansion coefficient, thermal conductivity is higher, duplex stainless steel 2205 alloy compared with austenitic stainless steel, it is twice its compression strength, compared with 316 l and 317 l, designers can reduce the weight, also can be used to lower the temperature, on the high speed machine tools, the alloy feed rate and cutting speed and 316 l is the same. If the carbide tool, cutting speed and the performance of the machine and its parts play a key role here.
Stainless steel plate of the duplex microstructure helps to improve the ability of resistance to stress corrosion cracking of stainless steel. In a certain temperature, tension, the presence of oxygen and chlorine, austenitic stainless steel chloride stress corrosion will happen. As a result of these conditions is not easy to control, so the use of 304 l, 316 l and 317 l in this area is restricted, duplex stainless steel uns c68700 corrosion resistance is superior to the ordinary 316 l austenitic stainless steel, and some medium, such as acetic acid, formic acid and so on can even replace austenitic stainless steel, high alloy and corrosion resistant alloy.
Within the concentration range of pure phosphoric acid and its corrosion resistance is very good. In wet process of industrial phosphoric acid, impurity against corrosion has a strong influence. In all the various kinds of phosphate, 904 l stainless steel corrosion resistance is superior to the ordinary. In strong oxidizing nitrate, compared with the high alloying steel does not contain molybdenum, low corrosion resistance. In hydrochloric acid, used in low concentration. In this concentration range. Good corrosion resistance to the conventional stainless steel 904 l. 904 l steel has high corrosion resistance.
Stainless steel plate in the uns c70600 crevice corrosion resistance in chloride solution is also very good. 904 l high nickel content, reduced the hemp pit and the corrosion rate of gaps. Ordinary austenitic stainless steel when temperature is higher than 60 degrees Celsius, in a rich chloride environment sensitive to stress corrosion may be, by improving the nickel content of stainless steel, can reduce the sensitization. Because of the high content of nickel, 904 l in chloride solution, concentration of hydroxide solution and rich hydrogen sulfide environment, has the very high resistance to stress corrosion cracking ability.
