Ambica Steels is the largest producer of Duplex Stainless Steel Long Products in India. Ambica Steels produces these materials for a wide variety of applications and industrial sectors. These user segments are the benchmark for quality. Every part is continually and stringently checked for quality and certified. Ambica’s steels are melted, cast and formed with the perfection and care.
Due to its two-phase microstructure, Duplex steels are extremely tough to produce. It took Ambica Steels many years of constant trials & errors, before gaining a complete control over this steel. The dual phase structure demands a perfect balance in the chemistry of these steels. Duplex steels also show an irregular behavior when undergoing various hot working processes. But thanks to the strong determination of our Research & Development team, as Ambica Steels now enjoys the reputation of being one of the most reliable supplier of Duplex materials in domestic as well as the international market.
Duplex Stainless Steel Long Products are the family of steels that have a mixed micro-structure of 50% ferrite and 50% austenite. They are known to offer exceptional strength and astounding aesthetic qualities along with better resistance against corrosion and high temperature, superior hygienic surface finishing, and improved steel recyclability.
At Ambica Steels, we are committed to ensure the development of highly sustainable long products that meet the expectations and requirements of our clients. As a result of our drive to continuously improve and transform our products, we manufacture customized duplex stainless products in our ultra-modern production facilities in multiple grades and sizes.

|303 300||303 grade represents the optimum in machining among the austenitic stainless steels. It is primarily used when production involves extensive machining. 303 is available in Improved Machining grade with machining characteristics significantly higher than that of the standard 303. Sorte 303 bietet das Optimum an austentischem Edelstahl f�r maschinelle Bearbeitung. Es wird haupts�chlich verwendet, wenn bei der Produktion extensive maschinelle Bearbeitung angewendet wird. 303 gibt es als Sorte ?Improved Machining? mit verbesserten Verarbeitungseigenschaften, als bei Standard 303.|
|304 304||304 grade is dual certified as grade 304 and 304L. Grade 304 is the standard "18/8" stainless. It has excellent forming and welding characteristics. Grade 304L, the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge components. 304 is available in Improved Machining grade with machinability significantly higher than that of the standard 304. Sorte 304 grade ist zweifach zertifiziert als Sorte 304 und 304L. 304 ist der Edelstahlstandard ?18/8?. Sie bietet exzellente Formungs- und Schwei�eigenschaften. 304L ist die Version von 304 mit weniger Kohlenstoff und ben�tigt kein Gl�hen nach dem Schei�en und wird deshalb haupts�chlich bei schweren Stahlteilen verwendet. 304 gibt es als Sorte ?Improved Machining? mit verbesserten Verarbeitungseigenschaften, als bei Standard 304.|
|316 316||316 grade is dual certified as grade 316 and 316L. 316 is the standard molybdenum-bearing stainless steel, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. 316 is available in Improved Machining grade with machinability significantly higher than that of the standard 316. Sorte 316 ist zweifach zertifiziert als 316 und 316L. 316 ist der Standardedelstahl mit Molybd�n und unter den austentischen Stahlsorten die wichtigste nach 304. Das Molybd�n bietet 316 verbesserte Korrosionsqualit�ten als 304, speziell im Bereich von Loch- und Spaltkorrosion in Chlorid-Umgebungen. ?. Sie bietet exzellente Formungs- und Schwei�eigenschaften. 316 gibt es als Sorte ?Improved Machining? mit verbesserten Verarbeitungseigenschaften, als bei Standard 316.|
|420 420||420 grade can be hardened by quench-and-temper heat treatment. It contains a minimum of 12 per cent chromium, just sufficient to give corrosion resistance properties. It has good ductility in the annealed condition but is capable of being hardened up to Rockwell Hardness 50HRC, the highest hardness of the 12 per cent chromium grades. Its best corrosion resistance is achieved when the metal is hardened and surface ground or polished. 420 is available in Improved Machining grade with machinability significantly higher than that of the standard 420. Sorte 420 kann durch Verg�tungs-W�rmebehandlung geh�rtet werden. Sie hat mindestens 12% Chrom, um gerade genug Korrosionswiderstand zu haben. Sie bietet gute Dehnbarkeit im verg�teten Stadium und kann bis zu einer Rockwell H�rte von 50HRC geh�rtet werden, der h�chsten Stufe der 12%-Chrom-Sorten. Der beste Korrosionswiderstand wird erreicht, wenn das Metall geh�rtet wird und auf einer oder beiden Seiten geschliffen wird. 420 gibt es als Sorte ?Improved Machining? mit verbesserten Verarbeitungseigenschaften, als bei Standard 420.|
|431 431||431 grade is a heat treatable martensitic, nickel-bearing grade has the best corrosion resistance properties of all the martensitic grades. It has excellent tensile and torque strength, and good toughness, making it ideally suited to shafting and bolt applications. It can be hardened to approximately 40HRC. Because of its high yield strength, this grade is not readily cold worked and is therefore not recommended for use in operations such as cold heading, bending, deep drawing or spinning. 431 is available as in Improved Machining grade with machinability significantly higher than that of the standard 431. Sorte 431 ist eine aush�rtbare, martentistische, nickelhaltige Sorte mit den besten Korrosionswiderstandeigenschaften aller martentistischen Sorten. Sie bietet exzellente Zugst�rke und Rei�festigkeit, sowie eine gute Z�higkeit, was sie ideal passend f�r Wellen- oder Schraubenanwendungen macht. Es kann bis zu 40HRC geh�rtet werden. Durch seine hohe Dehngrenze ist diese Sorte nicht ohne weiteres kalt Verformbar und somit ungeeignet f�r Anwendungen im Bereich Kaltstauchung, Biegung, Tiefziehen oder Dr�cken. 431 gibt es als Sorte ?Improved Machining? mit verbesserten Verarbeitungseigenschaften, als bei Standard 431.|
|2205 2205||2205 grade is the most widely used duplex (ferritic/austenitic) stainless steel grade. It finds applications due to both excellent corrosion resistance and high strength. Sorte 2205 wird meist als Duplex Edelstahl verwendet (ferritisch/austentisch). Sie hat exzellenten Korrosionswiederstand und eine hohe St�rke.|
