well a steel sword can very in weight. But i bet it is very heavy.

It's a misnomer. 4140 is a type of steel, which is NOT stainless.

Preparation: Ensure the 4140 steel workpiece is clean and free of any contaminants, rust, or scale. Place the workpiece in a heat-resistant container or fixture that allows for uniform heating and cooling. Heating: Preheat the furnace or kiln to the annealing temperature, which is typically around 1600°F (871°C) for 4140 steel. Insert the workpiece into the preheated furnace. Make sure it is supported and positioned to ensure even heating. Allow the steel to soak at the annealing temperature for a sufficient amount of time to ensure uniform heating. The soak time may vary but can be in the range of 1 to 2 hours.
I think you're looking at two separate terms. SAE 4140 steel is a Chromium-Molybdenum steel used extensively for axles, aerospace concerns, and firearm manufacture. Mild steel is a catch-all term for plain carbon steel of low carbon content (such as SAE 1018) which is generally cheap, not heat-treatable, and used for fairly low-strain applications. I hope that helps. Mike Source - Machinery's Handbook, 11th Edition, 1943
No, 4140 is an integer and integers cannot be simplified.

The first two digits indicates a Chromium-Molybdenum alloy steel the last two digits indicates carbon content roughly 0.4 percent.
It will be at least 117,000 psi and as high as 290,000 psi - the range depends on the tempering temperature and heat treat
