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 ...

Its machining properties were improved by modifying ... and drop-in replacement for conventional 15Cr-5Ni stainless, a steel alloy used for decades in aerospace. Project 70+ meets all aerospace ...

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.

It’s a frustrating fact that whenever you try to improve materials like steel, you end up introducing new weaknesses at the same time. It’s a balancing act between different properties.

Those two properties are usually at odds with each ... The team treated a steel alloy known as T-91 to produce a new material they call Gradient T-91 (G-T91), which, as the name suggests, has ...
