300 Series austenitic stainless ste

300 Series austenitic stainless steel has austenite as its primary phase (face centered cubic crystal). These are alloys containing chromium and nickel, and sometimes molybdenum and nitrogen, structured around the Type 302 composition of iron, 18% chromium, and 8% nickel. 200 Series austenitic stainless steels replace the majority of their nickel content with manganese to reduce cost. Austenitic steels are not hardenable by heat treatment. The most familiar stainless steel is probably SAE 304 stainless steel, also called 18/8 or A2 stainless steel. Type 304 surgical stainless steel is an austenitic steel containing 18-20% chromium and 8-10% nickel.

Alloy 20 (Carpenter 20) is an austenitic stainless steel possessing excellent resistance to hot sulfuric acid and many other aggressive environments which would readily attack type 316 stainless.This alloy exhibits superior resistance to stress-corrosion cracking in boiling 20-40% sulfuric acid. Alloy 20 has excellent mechanical properties and the presence of Niobium in the alloy minimizes the precipitation of carbides during welding.[1]

Austenitic stainless steel can be tested by nondestructive testing using the dye penetrant inspection method but not the magnetic particle inspection method. Eddy-current testing may also be used. It is the primary stainless steel used in aviation construction. Chemical and steel industry-applicable grades are SAE steel grades 308, 308L, 316, 316L, 316LN (nitrogen bearing), 312, 309L, and 310L. "L" denotes a carbon percentage less than 0.03%, mostly used for corrosion heat resistance and reducing sensitivity to chromium carbide formation. Another grade, 312, is used for dissimilar steel welding, also known as universal alloy steel as unknown composition steels can be welded. For high temperature applications at greater than 600°C, grades 309 and 310[2] are preferred. Grade 316 is alloyed with molybdenum (~2–3%) for high-temperature strength, pitting and crevice corrosion resistance.

300 series baja stainless steel mempunyai austenite sebagai fase utama (wajah berpusat kristal kubik). Ini adalah paduan yang mengandung Kromium dan nikel, dan kadang-kadang molibdenum dan nitrogen, terstruktur di sekitar komposisi jenis 302 besi, Kromium 18% dan 8% nikel. 200 seri baja stainless baja mengganti sebagian besar isinya nikel dengan mangan untuk mengurangi biaya. Baja baja tidak hardenable oleh perlakuan panas. Mungkin paling akrab stainless steel adalah SAE 304 stainless steel, juga disebut 18/8 atau A2 stainless steel. Jenis bedah stainless steel 304 adalah baja baja yang mengandung nikel 18-20% Kromium dan 8-10%.Paduan 20 (Carpenter 20) adalah baja stainless baja memiliki sangat tahan terhadap panas asam sulfat dan banyak lingkungan agresif lainnya yang mudah akan menyerang jenis 316 stainless. Paduan ini pameran unggul perlawanan terhadap stres-korosi retak dalam mendidih asam sulfat 20-40%. Paduan 20 memiliki sifat mekanik yang sangat baik dan kehadiran Niobium dalam paduan meminimalkan presipitasi carbides selama pengelasan.
