Austenite, also known as gamma-phase iron (γ-Fe), is a metallic, non-magnetic allotrope of iron or a solid solution of iron with an alloying element. [1] In plain-carbon steel, austenite exists above the critical eutectoid temperature of 1000 K (727 °C); …

Austenite: It is a solid solution of iron-carbon which is stable only within a particular range of composition and temperature, and is non-magnetic. On cooling below 700°C it is completely transformed into ferrite which is magnetic and cementite to form the eutectoid pearlite, together with free ferrite or free cementite, depending on whether ...

Austenitic stainless steel is one of the five families of stainless steel (along with ferritic, martensitic, duplex and precipitation hardened). [1] Its primary crystalline structure is austenite (face-centered cubic). Such steels are not hardenable by heat treatment and are essentially non-magnetic. [2] This structure is achieved by adding ...

2021年10月22日 · Austenitic stainless steel is the most commonly used stainless steel type due to its excellent mechanical properties and aesthetic appearance. The steel has high corrosion resistance thanks to its high chromium content. This makes austenitic stainless steel suitable for harsh operating conditions.

2024年8月8日 · Austenitic stainless steel is one of the five major classes of stainless steel defined by crystalline structure with a face-centered cubic (FCC) crystalline structure, primarily composed of 15-32% chromium and 8-37% nickel, with a balance of …

2024年7月19日 · Austenitic steel is a type of stainless steel that contains austenite. It contains a high percentage of nickel and chromium, enhancing its ability to be formed and welded easily into any shape along with providing great strength and resistance to corrosion.

2021年3月27日 · The main difference between austenitic and ferritic stainless steel is that the former features a crystalline structure, whereas the latter contains a higher concentration of chromium. Another difference between these two types of …

2024年10月24日 · Austenitic stainless steel has a well-rounded set of properties, particularly outstanding resistance to oxidizing acids. It can resist corrosion from sulfuric acid, phosphoric acid, formic acid, acetic acid, and urea.

2023年9月3日 · Austenitic stainless steel is a type of steel alloy that is renowned for its exceptional corrosion resistance and versatility. It derives its name from its crystalline structure, which is predominantly austenite.

What is Austenitic Stainless Steel? Stainless steel, including austenitic stainless steel, is popular for its strength, durability, and corrosion resistance. It's aesthetically pleasing, easy to produce, clean, and maintain, and environmentally friendly, making it a top choice for components for architecture, automobiles, and many other products.

Austenite is a key metallurgical phase that forms in iron and steel alloys under specific thermal conditions. It typically forms at temperatures above 723°C, a point known as the eutectoid temperature.

2018年5月12日 · Austenite is a non-magnetic allotrope of iron. It is named for Sir William Chandler Roberts-Austen, an English metallurgist known for his studies of metal physical properties. Also Known As: gamma-phase iron or γ-Fe or austenitic steel. Example: The most common type of stainless steel used for food service equipment is austenitic steel.

2023年8月19日 · Austenite, with its unique face-centered cubic structure, plays a crucial role in metallurgy. This article delves into the formation, properties, and applications of austenite, explaining how its behavior impacts everything from toughness to corrosion resistance.

Austenitic stainless steels contain austenite, a form of iron which can absorb more carbon than ferrite. Austenite is created by heating ferrite to 912 degrees C, at which point it transitions from a body centred cubic crystal structure to a face centred cubic crystal structure.

2023年12月21日 · Thanks to its great workability, excellent corrosion resistance and ease of manufacture, Austenitic stainless steel is found in all walks of life. In medical settings, it is used to make trays, counter tops and trolleys, as well as components in medical devices such as staple guns and other hand tools.

2020年5月25日 · Austenitic stainless steels are the most popular grade among the stainless family of alloy steels and are known for their high corrosion resistance and temperature stability over a wide range. Did you ever wonder how the austenitic stainless steels differ from other categories of stainless steel?

Austenite is iron but in a metallic form. It is one of the allotropes of iron, which means its physical form is different from iron, but its chemical form is the same. [1][2] It is named after Sir William Chandler Roberts-Austen (1843–1902). [3] Austenitization means to heat iron, iron-based metal, or steel to a high temperature.

Austenitic stainless steel is the largest family of stainless steel, making up two-thirds of all stainless steel production. Their yield strength is low (200 to 300MPa), which limits their use for structural and other load-bearing components.

Stainless steel grades with an austenitic microstructure are typically easy to fabricate, have good toughness, good corrosion resistance, and consistent mechanical properties across a wider range of temperatures and are non-magnetic.

2025年2月8日 · H.W. Luo et al. [17] have demonstrated that the impact toughness of Ultra High Strength Steel (UHSSS) is contingent upon the frequency and capability of strain-induced phase transformation in capturing propagating cracks at the grain boundaries and martensitic lath interfaces of retained austenite (RA). Z.J. Xie et al. [18] achieved fine film-like stable retained …

2025年2月1日 · To determine whether the presence of such retained austenite in tempered martensitic structures could be detrimental to fatigue resistance in HP 9-4-20 steel, fatigue crack propagation behavior ...

2025年1月17日 · ステンレス製品にはさまざまな種類があり、その中でもオーステナイト系ステンレスは非常に人気があります。一体どのような特徴や選び方があるのでしょうか？本記事では、オーステナイト系ステンレスの種類とその特徴について詳しく解説します。ステンレス素材
