Common Application

Stainless Steel

304

l  Housings, bodies. SS304 is widely used in medical, plumbing,   watering, mining and petrochemical industries as the standard for cleanliness   as well as corrosion resistance.

316

l  Housings, gears, plates. Superior corrosion resistance of SS316   makes it ideal for many applications including automotive, food & diary   and petrochemical environments.

304L/316L

l 
  Similar to other 300 series steel, low carbon makes it softer but more   corrosion resistant. Ideal industries are such as food & dairy, medical   and petrochemical.

l   

410 & 416

l 
  Housings, bushings, handles, brackets. 400 series steels are high strength   and very machinable. They will tend to break rather than bend under intense   pressure. Ideal industries are automotive, food & dairy and various   machine tools.

l   

17-4

l  Very strong. Can be used in military, various machine tools etc.

Duplex Stainless Steel

2205

l  Duplex stainless steel 2205 consists of a two-phase microstructure   — both ferritic stainless steel and austenitic stainless steel. Nitrogen is   enhanced in Duplex 2205 comparing to other duplex stainless steel.

Super Duplex Stainless Steel

2507

l  Desalination, marine, pulp & paper mill, chemical process   pressure vessels, heat exchangers and piping, oil and gas industry, offshore   oil industry.

Zeron 100

l  Desalination, flue-gas desulfurization, oil and gas industry,   pollution control, chemical, pharmaceutical, mining and mineral industries,   pulp and paper, power generation, marine industries

Titanium

Grade 2

l  Chemical process, marine etc.

Carbon Steels

1000 series

l  Softest of common carbon steels. More likely to bend rather than   break under intense pressure. Commonly used to make cranks, handles, and   braces.

4100 series

l  High strength material that is used when deformation of a part is   not allowed. Commonly used to cast firearm components and ratchets.

8600 series

l 
  8600 series is stronger than 1000 series but will bend prior to breakage. Commonly   used to cast firearm components, housings, and nozzles.

l   

Tool Steels

A2, S7, D2

l  Used when parts will be under higher heat due to less distortion.   Not corrosion resistant like stainless steel.

Aluminum Alloys

A356

l 
  Housing, covers, plates. Aluminum is lightweight and extremely corrosion   resistant like stainless steel.
