AISI 4140 alloy steel can be welded using all conventional techniques. However, the mechanical properties of this steel will be affected if it is welded in the heat-treated condition, and post-weld ...

AISI 8620 alloy steel is a common, carburizing alloy steel. This alloy steel is flexible during hardening treatments, thus enabling improvement of case/core properties. The following datasheet will ...

"It is about 3-4 times harder than most steels," said Emilia Morosan, the lead scientist on a new study in Science Advances that describes the properties ... version of the alloy—the crystal ...

While the bare steel rusted significantly ... Perhaps most impressively, the team found the alloy to have powerful self-healing properties. When a film of it was cut in half and the two pieces ...

SAE 781 contains 1 to 3% cadmium for improved bearing properties. This alloy is used in making steel-back bearings with a 0.0005-in. overlay containing approximately 90% lead and 10% tin.
