1.Overview.
1.7075 stainless steel is a high-quality chromium-nickel stainless steel with good corrosion resistance, high strength and toughness. As a special alloy, 17075 stainless steel is widely used in many fields such as chemical, pharmaceutical, food and beverage, medical device and aerospace. This article will go into more detail about 1Corrosion resistance performance parameters, chemical composition, and summary uses of 7075 stainless steel.
2.Corrosion resistance parameters.
2.1 Corrosion test.
1.In the sulfuric acid-copper sulfate corrosion test of 7075 stainless steel, the corrosion rate of the specimen within 24 hours is only 225 mm year, showing extremely high corrosion resistance. In the salt spray test, the corrosion area of the specimen increased by only 125 mm², showing excellent corrosion resistance.
2.2 Antioxidant properties.
1.7075 stainless steel has good oxidation resistance at high temperatures and is not easy to produce oxidative corrosion. In the thermal stability test, the sample remained stable at high temperature, and there was no obvious change on the surface, which proved its good oxidation resistance.
2.3 High temperature intensity.
1.7075 stainless steel retains high strength at high temperatures. In the high-temperature strength test, the tensile strength of the specimen at 600 can reach more than 450MPa, which is much higher than that of ordinary stainless steel. This makes 17075 stainless steel has good compressive resistance in high-temperature applications.
