AMBICA STEELS PRODUCED VARIOUS STAINLESS STEEL PRODUCTS OF DIFFERENT GRADES, AUSTENITIC STAINLESS STEEL IS ONE OF THEM i.e AISI 300 SERIES GRADE.
Austenitic steels are non-magnetic stainless steels that contain a high level of chromium & nickel with a low level of carbon content. Austenitic steels are the most widely used grade of stainless steel; the most common composition is 18% Cr and 8% Ni i.e. 18/8-steels.
Austenitic steels are generally classified into two groups –the Chromium- Nickel AISI 300 series type and Chromium –Nickel- Manganese 200 series type. Steel with better resistance to corrosion is created by adding 2-3% molybdenum, which is often called “acid-proof steel”. Grade 304 is the most common grade of this type, which typically contains 18 percent chromium and 8 percent nickel.
These steels are the most popular grades of stainless steel produced because of their excellent formability, impact strength and corrosion resistance. Another reason for choosing this type of steel is high creep strength and scaling resistance.
Work hardening rate of some austenitic stainless steels is high.In that case, austenite is not stable and will partially transform to martensite when it is cold worked. Ambica is producing cold-worked austenitic stainless steels in a number of industry standard strength levels. for ex-Grade 301 has the lowest nickel (6.5%Ni) content and has thus the highest rate of work hardening.
Ambica Steels produces all materials in this grade – Bright Round Bars, PSQ Bars, HRAP Flat Bars, HR Bars & RCS, Cold Drawn Round/Flat/Square/Hexagon Bars, Concast Billets, Ingots.
Austenitic stainless steels are generally exhibits excellent formability.
In welded joints, good mechanical strength is developed without the necessity of preheating or post-weld annealing.It is advised to use heat treatment process or alternative selection of low carbon grades to prevent corrosion in the weld area.
These steels are well suited to both higher service temperatures of around 600°C – or even higher if scaling resistance is the only consideration and extremely low cryogenic temperatures, depending on the load and permissible distortion.
At sub-zero temperatures, some austenitic steel grades retain good ductility and impact strength. These alloys also maintain tensile and creep strength at elevated temperatures.
They are used for the storage of liquefied gases at cryogenic temperatures and for heat exchangers & pollution control equipment at high temperatures.
Austenitic stainless steels are used in a wide range of applications, including automotive trim, Cookware, Food and beverage equipment, Industrial equipment etc.
Applications by Grade
Used for Tanks, Storage vessels and pipes for corrosive liquids, mining, chemical, cryogenic, food and beverage, Cutlery, Architecture, Sinks, food processing, domestic sinks and tubs, pharmaceutical equipment and deep drawing applications
Furnace parts and equipment, kiln, and catalytic converter components.
Also resistant to temperature 900°C to 1100°C.
Used where higher corrosion resistance is required, i.e. marine equipment, Chemical storage tanks, pressure vessels, and piping.
A titanium stabilised version of 316 is used where high temperature strength & good resistance to intergranular corrosion is required. Also used for superheaters, compensators & expansion bellows.
Used for Dishwashers and Washing machines, Cutlery and Cookware, In-house water tanks, Non structural architecture, Food & Beverage equipment and Automobile Parts etc.
