Oil Patch Alloys |
|
 |
 |
|
|
One of the harshest environments on Earth is beneath your feet - deep under ground.
For successful oil and gas exploration and extraction, designers need to select high-strength alloys that resist acids, seawater and other harsh chemicals.
Visit Carpenter's technical information database for alloys that may be considered for the oil and gas industry.

PM for Orthopaedic Implants |
|
|
 |
|
 |
 |
Coarse grain size. Non-uniform microstructural segregation. Lower tensile and fatigue strength.
Engineers are likely to encounter these limitations when using conventionally cast, cobalt-based ASTM F75 to manufacture orthopaedic implant parts.
These problems can be avoided by switching to a cobalt-chromium-molybdenum wrought bar stock made from the powder metallurgy process. Advantages include eliminating the need for cold drawing and annealing, and the ability to make smaller diameter bar and wire.
Tests compared conventional castings and PM wrought bar stock for this application. |

Problem Solved! Fasteners |
|
|
|
|
|
|
Designers often have to make sacrifices when specifying a hardenable stainless steel for a fastener application.
They are often forced to sacrifice good corrosion resistance, cold formability, or higher hardness because a good combination of all three properties simply did not exist in one alloy. Until now, that is.
Trinamet stainless, developed recently by Carpenter, offers an improved combination of all three properties for the fastener industry.
