240 MPa (Yield) 0.2% Proof

149 HB (Typical)

300 series Austenitic Grade with Excellent Weldability and forming in a wide range of applications. The 304 grade exhibits good Corrosion resistance.

Typical Applications include:

  • Kitchen Bench Tops
  • Splash Backs
  • Food Storage
  • Wine Tanks

316/L

UNS S31600, UNS S31603

290 MPa (Yield) 0.2% Proof

149 HB (Typical)

Popular “Marine” grade of Stainless from the 300 series Austenitic family. The 316 grade provides Excellent Weldability and forming. Added Molybdenum provides a superior corrosion resistance to a wider range of chemicals than the 304 grade.

Typical Applications include:

  • Mining Screens
  • Boat components
  • Architectural Panels
  • Paper Production Mills

 

3CR12 / 5CR12

EN 1.4003, UNS S40977, UNS S41003

330 MPa (Yield) 0.2% Proof

180 HB (Typical)

These grades are known as Utility Stainless Steels from the Ferritic family. Both grades are easily welded and formed.

3cr12 & 5cr12 provide good Abrasion resistance in wet environments with limited corrosion resistance.

Typical Applications include:

  • Ore wagon bodies
  • Oven Components
  • Cattle Trucks
  • Mining applications

 

ALUMINIUM

5005

O Temper

35 MPa (Yield) 0.2% Proof

H32 Temper

85 MPa (Yield) 0.2% Proof

H34 Temper

105 MPa (Yield) 0.2% Proof

The 5005 grade of aluminium is a general utility 0.8% Magnesium alloy grade that can be used in a wide range of applications. The 5005 grade exhibits good weldability and formability. Machining of the grade improves in the higher tempered versions. The addition of Magnesium increases the strength of the 5000 series Alloys.

Typical Applications include:

  • Cooking Equipment
  • Architectural signs
  • Wiring

5052/5251 TREAD PLATE

These popular 5000 series 2-2.5% Magnesium alloy plates exhibit 5 bar raised patterns on one side and are available in both grades 5052 and 5251. They can be used in safety areas as well as decorative applications.

Typical Applications include:

  • Boat floors
  • Trailers
  • Tool Boxes
  • Stair Treads

5083

O Temper

115-200 MPa (Yield) 0.2% Proof

H32 Temper

215 MPa (Yield) 0.2% Proof

H116 Temper

215 MPa (Yield) 0.2% Proof

The Alloy 5083 grade of aluminium is a high strength grade with 4½% Magnesium. The product is easy to weld, however it is harder to form and machine due to the high strength. The product exhibits excellent Corrosion resistance and is well known for its use in Marine environments.

Typical Applications include:

  • Food Processing
  • Architecture
  • Boat Fabrication
