In Season 2 episode 5 of The Mandalorian, we see Din block a lightsaber with his arm. Is it ever explained anywhere how Beskar armor is strong enough to block a lightsaber?

Numerous times during the movies we see a lightsaber cut through a solid blast door with ease. If this is the case, how does a thin layer of Beskar armor deflect it?

    It was quite difficult to cut through blast door. Poor Qui-Gon wasted a lot of time and still didn't open it. So, I guess beskar is similar, just that normal output from lightsaber is not enough to melt it - energy gets dissipated too fast for the metal to reach melting point.

    For a counter-argument, you may with to read M. Windu, "Field Notes from the Battle of Geonosis: The Critical Omission of Bevors from Mandalorian Armor", reporting field experience of successful attacks versus Mandalorian armor. A popularized synopsis appears here. Commented Nov 20, 2021 at 0:25

    @RobbieGoodwin: Because super-hot plasma should be able to melt any solid material. (Or burn or vaporize, if that happens first when transferring huge amounts of heat into it.) Star Wars is supposedly set in our universe (a long time ago in a galaxy far far away), although this wouldn't be the only case of things working in ways that are inconsistent with our understanding of physics. (e.g. banked turns in space; I'm not talking about "magic" such as force powers) Commented Nov 21, 2021 at 3:31

    It's literally plot armor. Commented Nov 22, 2021 at 2:45

In the current Star Wars canon, Beskar, also known as Mandalorian iron, is an alloy used in Mandalorian armor, notable for its high tolerance to extreme forms of damage. The metal was durable enough to withstand a direct blaster shot and could repel lightsaber strikes.

From the Star Wars Databank:

BESKAR Mandalorian armor forged from beskar can withstand blaster bolts, nearly impenetrable protection that made the warrior class difficult to defeat at the height of their power. After the fall of the Empire, the nearly indestructible steel is harder to come by. https://www.starwars.com/databank/beskar

Durability — the ability to withstand wear, pressure, or damage — is a common property of metals, and beskar is a metal which has extremely high durability.

By the time of your questioned S2 E5 episode, the Mandalorian has managed to fashion portions of his armored suit out of beskar. This allowed the Mandalorian to deflect the lightsaber strike.

As to your other point, blast doors are not typically made from beskar. Consequently, we see numerous times during the movies where a lightsaber cuts through a solid blast door with ease. Because this is the case, the standard blast door could benefit from a thin layer of beskar armor to deflect lightsabers if such an attack is anticipated. However, by the time of the movies (OT & ST), both lightsabers and beskar are relatively rare.

    It wouldn't be cost efficient at all to layer ALL blast doors with Beskar. The chance for a jedi or sith to show up at your doorstep is a risk so low, no reasonable manufactorer would consider protecting against it. Especially after order 66..

    @Mixxiphoid To that point, the median number of lightsabers in Star Wars movies is 2. Commented Nov 19, 2021 at 11:17

    Also from Mandalorian, Beskar armor also appears to attract blaster bolts (which it absorbs, harmlessly). Stormtroopers firing at Mando go from their usual (lack of) accuracy in completely missing their target, to precisely hitting him, but only in those locations that have the armor.

    @EricDuminil You might not have heard of it, but you absolutely saw it onscreen in both Jango’s and Boba’s armors in current canon. Commented Nov 19, 2021 at 16:58

Beskar is a Fantasy Metal and also serves as Unobtainium:

In fiction, especially fantasy, a metal is shiny stuff with wonderful properties like super strength, lightness, magic resistance and so on, often not resembling any of the metals found in the periodic table. (...) Beskar (...) [is] more or less the local version of adamantium.

So, strictly speaking, there is no in-universe explanation for how the mandalorian armor does stop a lightsaber. It is made from Beskar. But why does Beskar resist a lightsaber?

For more lightsaber-resistant materials from the Star Wars universe see Cortosis, Phrik, Ultrachrome and Songsteel.
