304ステンレス鋼は医療グレードですか？

2021年8月12日 カテゴリ: /作成者:

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 the upper limit of ordinary stainless steel), while the content of impurity elements such as S and P is lower than that of ordinary stainless steel. For years, medical stainless steel has been the preferred material for surgical applications, especially in critical care and surgery situations. The element Ni and Cr feature higher corrosion-resisting, which […]

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, 320, No.7, No.8, HL, BA, TR hard state, embossed surface grade. It can be further applied to electroplating, electropolishing, undirected hairline, etching, shot peening, coloring, coating and other deep-processing surfaces based on the cold-rolled stainless steel. Stainless steel cold rolled sheet is widely used in construction, decoration, home appliances, rail transportation, automobile, elevator, container, solar […]

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) stainless steel. 8K surface (No.8) is the mirror-polished surface, high reflectivity, clear reflection image, usually with resolution and surface defect rate to measure the quality of mirror stainless steel, general visual assessment: level 1 is the surface bright as a mirror, can clearly see the human features and eyebrows; Level 2 is the surface is […]

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 the C75 steel grade with Martensitic stainless steel grades of 9Cr and 13Cr   High strength Martensitic stainless steel pipe for oil well  In the wet environment with CO2 as the main gas, local corrosion damage of oil well pipe often occurs, such as pitting corrosion and intergranular corrosion, etc. If Cl – exists, the local […]

合金元素はステンレス鋼にどのような影響を与えますか？

2021年8月9日 カテゴリ: /作成者:

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 lattice atoms (gap position) due to small volume, produce huge strain in the lattice, so become effective hardening elements. Different alloying elements have different effects on the properties of steel, sometimes beneficial and sometimes harmful. The main alloying elements of Austenitic stainless steel have the following effects:   Cr Chromium is an alloying element that […]

歯科用器具はなぜステンレス鋼で作られているのですか？

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 find the cavity and pressure area of the tooth so that the restorative material can be placed. They have a variety of angles and pointed shapes, so the dentist can freely reach all sides of the teeth. A variety of materials are available to manufacture dental instruments, including stainless steel, carbon steel, titanium, and plastics. […]
