Corrosion Resistant - Stainless Steel Alloys
Castings are classified as “corrosion resistant” if they are used in aqueous environments and vapours below 650°C. To perform well in a corrosive environment the carbon content should be low and usually below 0.20% and sometimes below 0.03%. Based on microstructure Corrosion resistant cast alloys are grouped as Martensitic, Austenitic, or Duplex.
High Strength to Weight Ratio and Corrosion Resistance
Titanium offers a high strength to weight ratio and extraordinary corrosion resistance, making it an ideal choice for medical, marine, hand tools, sporting goods, and high performance automotive applications.
Wear and Abrasion Resistant
Castings are classified as wear and/or abrasion resistant if during applications where constant or high friction occurs the alloys have minimal loss in mass and do not deform due to friction force. These alloys are almost always of high hardness. This hardness is achieved by the formation of carbides within the metal which are very abrasion resistant.
Heat Resistant Alloys
Castings are classified as heat resistant if they are capable of sustained operation while exposed, either continuously or intermittently to operating temperatures that result in material temperatures in excess of 650°C. The application of heat resistant alloys depends on
Resistance to corrosion at elevated temperature
Stability - resistance to warping, cracking, thermal fatigue at elevated temperature.
Creep strength
Alloys for Cryogenic Applications
The austenitic stainless steels and titanium alloys possess a unique combination of properties which makes them useful at cryogenic (very low) temperatures, such as are encountered in plants handling liquefied gases. These materials at cryogenic temperatures have tensile strengths substantially higher than at ambient temperatures while their toughness is only slightly degraded.
Low Magnetic Permeability
Supreme can produce a range of alloys that have low magnetic permeability's of 1.05 Mu or lower. We have the capability to report the magnetic permeability of alloys in accordance with ATSM A342 method 3. Supreme can produce and measure the magnetic permeabiltiy of alloys to lower than 1.01 Mu.
Non Sparking Alloys
Supreme can produce a range of alloys that can be used in environments where fires and explosions are a concern. These include industries where fluids both vapour and liquids, and particulates such as dust and residue are present and can be ignited.
