Stainless steel

Austenitic

Austenitic stainless steels are one of the most widely available steels due to their fair corrosion resistance, mechanical strength and toughness, workability and are non-magnetic. Austenitic steels have a massive range of applications from aerospace to food processing.

CF8M

Cast Grade: CF8M

Wrought Grade: 316

Tensile Strength, Ultimate: 485MPa

Tensile Strength, Yield: 205MPa

Elongation at break: 30%

Elemental Composition

Carbon, C <=0.08%

Chromium, Cr 18-21%

Iron, Fe 60.8-71%

Manganese, Mn <=1.5%

Molybdenum, Mo 2-3%

Nickel, Ni 9-12%

Phosphorous, P <=0.04%

Silicon, Si <=1.5%

Sulfur, S <=0.04

 

Applications: Valves, flanges, fittings and other pressure-containing parts

CF8M austenitic stainless steel is very popular for products requiring excellent overall corrosion resistance.

CF8

Cast Grade: CF8

Wrought Grade: 304

Tensile Strength, Ultimate: 485MPa

Tensile Strength, Yield: 205MPa

Elongation at break: 30%

 

Elemental Composition

Carbon, C <=0.08%

Chromium, Cr 18-21%

Iron, Fe 60.4-74%

Manganese, Mn <=1.5%

Nickel, Ni 8-11%

Silicon, Si <= 2%

 

Applications: Hydro turbines, valves and fittings, heating coils, pumps, spray nozzles etc.

CF8 provides good cavitation resistance which is very important in areas involving water handling, CF8 will also provide strong resistance to strongly oxidising environments and corrosive medial applications.

CF3

Cast Grade: CF3

Wrought Grade: 304L

Tensile Strength, Ultimate: 485MPa

Tensile Strength, Yield: 205MPa

Elongation at break: 35%

 

Component Elements Properties

Carbon, C <=0.03%

Chromium, Cr 17-21%

Iron, Fe 60-74%

Manganese, Mn <=1.5%

Nickel, Ni 8-12%

Silicon, Si <= 2%

 

Applications: Hydro turbines, valves and fittings, heating coils, pumps, spray nozzles etc.

Wrought grade 304L is the lower carbon variant of grade 304 steel, the lower carbon allows the steel to be welded without the resulting issue of carbon precipitation (reduces corrosion resistance of steel) and has similar corrosive and strength properties to grade 304. 304L is primarily used in severe corrosive environments due to its properties.

Super Austenitic

Super austenitic steel includes higher levels of chromium and higher levels of nickel together with additions of molybdenum and nitrogen. Although more expensive, the result forms a much stronger series of steel with superior resistance to pitting, crevice corrosion and stress corrosion cracking when compared to regular austenitic steel.

Type 254 SMO

​Cast Grade:

Wrought Grade:

Tensile Strength, Ultimate: 550MPa

Tensile Strength, Yield: 260MPa

Elongation at break: 35%

 

Carbon, C <=0.025%

Chromium, Cr 19.5-20.5%

Copper, Cu 0.5-1%

Iron, Fe 49.3-56.3%

Manganese, Mn <=1.2%

Nickel, Ni 17.5-19.7%

Nitrogen, N 0.18-0.24%

Phosphorous, P <=0.045%

Silicon, Si <= 1%

Sulfur, S <= 0.010%

 

Application: Seawater handling equipment, chemical process equipment, food processing equipment, desalination equipment.

 

Type 254 SMO steel is proven to have extremely high resistance to pitting and crevice corrosion with added resistance to chloride stress corrosion cracking. It is also 50% stronger than 300-series austenitic stainless steels with excellent impact toughness.

CF3

Cast Grade:

Wrought Grade:

Tensile Strength, Ultimate: 425MPa

Tensile Strength, Yield: 170MPa

Elongation at break: 35%

 

Chromium, Cr 19-22%

Copper, Cu 3-4%

Manganese, Mn 1.5%

Nickel, Ni 27.5-30.5%

Silicon, Si 1.5%

Carbon, C <=0.07%

Molybdenum, Mo 2-3%

 

Applications: Chemical processing, food and pharmaceutical industries and power plants.

CN7M exhibits exceptional corrosion resistance to sulfuric acid and good performance when handling pitting corrosion, crevice corrosion and stress-cracking corrosion These qualities make CN7M popular in production facilities where contact with other corrosive chemicals are necessary.

Duplex Stainless Steel

Duplex stainless steels have properties which gives it virtual immunity to stress corrosion cracking which is an issue in austenitic stainless steel and offers extra resistance to pitting and crevice corrosion. Exhibiting these qualities allows the use of Duplex Stainless Steel to be very effective in seawater related environments and has had many uses in oil and gas production and Naval equipment’s.

Alloy 86

Cast Grade: Alloy 86

Tensile Strength, Ultimate: 760MPa

Tensile Strength, Yield: 405

Chromium, Cr: 26%

Copper, Cu: 2.8%

Iron, Fe:

Manganese, Mn: 0.8%

Nickle, Ni: 6.8%

Silicon, Si: 0.7%

Carbon, C <=0.02

 

Applications: Piping systems, heat exchangers, reactors any equipment in a corrosive environment.

Non-Ferrous Alloys

Aluminium-Bronze

Aluminium bronze are a copper-based alloy containing aluminium as the principle alloying element. Aluminium bronze is among the highest strength standard copper based alloy that Adarsh we use. Its strength is comparable to that of medium carbon steel whilst also possessing excellent corrosion resistance. These properties and many other valuable characteristics led to the use of aluminium bronzes for a variety of parts requiring hardness, resistance to wear and galling, low magnetic permeability, erosion and oxidation at elevated temperatures. Aluminium bronze also has the capability to be heat treated and further increasing its tensile strength.

C95400

Cast Grade: C95400

Tensile Strength, Ultimate: 515MPa

Tensile Strength, Yield: 205MPa

Elongation at break: 12%

 

Aluminum, Al: 11%

Copper, Cu: 85%

Iron, Fe: 4%

C95900

Cast Grade: C95900

Tensile Strength, Ultimate: 515MPa

Tensile Strength, Yield: 345MPa

Elongation at break: 1%

 

Aluminum, Al: 13%

Copper, Cu: 82.5%

Iron, Fe: 4.5%

 

C95900 Aluminum bronze is an alloy that contains more than 9.5% Al which means it can also be heat treated to increase tensile strength. This allows the alloy to be used in a variety of heavy-duty mechanical and structure products including gears, worm drives, valve guides and seats.

Nickel Silver Bronze

Nickel Silvers are an alloy that contain copper, nickel, and zinc. These alloys are effectively used in applications where corrosion resistance or high electrical resistance properties are important and largely used in the food and beverage handling equipment, decorative hardware, electroplated table ware, optical and photographic equipment and musical instruments.
