Compared with industrial stainless steel, medical stainless steel has more strict requirements on chemical composition because of its main properties of reducing metal ion dissolution and avoiding local corrosion such as intergranular corrosion and stress corrosion. The content of alloy elements such as Ni and Cr is higher than that of ordinary stainless steel (usually […]
Stainless steel has become a widely used metal material for its excellent corrosion resistance, good mechanical properties and machining properties. Different processing methods and cold rolling after processing, stainless steel surface can have different levels of surface finish, grain and color. The surface processing of cold-rolled stainless steel plate has 2D, 2B, No.3, No.4, 240, […]
Because of its unique corrosion resistance, good processing performance and exquisite surface appearance, stainless steel has been widely used in many fields such as aerospace, energy, military, construction, petrochemical and so on. Polishing is an important part of the stainless steel plate in the decoration industry, its purpose is to get the final mirror (8K) […]
Generally speaking, some low alloy steels can meet the requirements for corrosive oil and gas environment containing H2S, but the corrosive environment containing CO2 or H2S, CO2, Cl – coexistence where the Martensitic stainless steel need, duplex stainless steel or even nickel-based alloy. The 1988 version of API 5CT added corrosion-resistant tubing steel grades, specified […]
Chemical composition has a great influence on the microstructure, mechanical properties, physical properties and corrosion resistance of steel. Chromium, molybdenum, nickel and other alloying elements can replace the vertex Angle of the austenite lattice and the center of the six sides of the cube iron, carbon and nitrogen are located in the gap between the […]
Many types of tools are used to clean and care for teeth, including probes, mirrors, scrapers, dental burnishers and pressors. Mirrors help examine the patient’s mouth, and scrapers scrape to remove plaque and tartar. The polisher gives a final finish to the fill, smoothing out scratches left by other tools. The probe is used to […]
