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 ).

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); …

2024年8月8日 · Austenitic stainless steels achieve their unique structure through the addition of alloying elements like nickel and chromium. In pure iron or plain-carbon steel, the austenitic (face-centered cubic) structure is stable only at high temperatures—around 1340°F (727°C) or higher.

2019年4月3日 · Austenitic steels are non-magnetic stainless steels that contain high levels of chromium and nickel and low levels of carbon. Known for their formability and resistance to corrosion, austenitic steels are the most widely used grade of stainless steel.

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7月19日 · What Does Austenitic Mean? Austenitic refers to an alloy consisting mainly of austenite. The most widely used grade of stainless steel is austenitic. Austenitic alloys contain a high percentage of nickel and chromium, which makes them, and the steel made from them, very resistant to corrosion.

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?

4 天之前 · Austenitic Stainless Steel: Typically contains less than 0.2% carbon to maintain the FCC crystal structure and ensure good corrosion resistance and mechanical properties. Ferritic Stainless Steel : Contains between 0.08% and 0.20% carbon, which supports the BCC crystal structure without compromising toughness.

Austenitic steels have large elongation, excellent toughness, and good corrosion and heat resistances. They are used across a range of temperature environments, from very low temperatures and up to high temperatures of ~1000°C.

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.
