#1 low-magnetic steel

Why don't magnets [magnetometers] work on some stainless steels?

Magnetometers are useful tools on Earth as the Earth is essentially a giant magnet. Magnetometers allow you to measure the strength and, depending on the instrument, the direction of a magnetic field at a point in space.

#2 If you can't track a austenitic stainless steel boat, perhaps one can identify traces of the Earth's variable magnetic fields that are being masked by the passage.

#3 The low-magnetic steel from which these submarines are made prevents enemy sonars from detecting them

That doesn't make a lot of sense to me, but then again, I don't take Russian dictation

#4 Sonar doesn't really care if the object is steel, wood, flesh or plastic (see 'Fishfinders'), Frank.

Perhaps it's the translation as you stated.

#5 Item 1: Sonar doesn't actually "see" the hull of submarine, it "sees" the air bubble inside. The change in density causes the reflection.
Item 2: Austenistic stainless is less magnetic than carbon steel. It is also considerably weaker.

#6 The article prolly is talking about detection from magnetic anomaly detectors fielded by aircraft.

IOW the translation s correct.

The application: not so much.
