The light hull of submarine are covered by

synthetic rubber called anechoic tile or bysound absorbing rubber

These material are used for decreasing

detection of the enemys radar

After stealth layer, there is outer hull thatmade of mild-carbon steel that does not need

strength

mild-steel is choosen because economical andtechnical consideration

To reduce the corosion mild-steel is coated by

mixed layer consist of various inorganiccoumpound Nitrate, Sulphate, Silicate, and

Chromate

Made of high-strength alloy steel or titanium

Both are ideal material, the point is we must make

inner hull shape perfect so the hull can distributing

stress

A little defect can make inner hull becomebent

Nuclear reactor rod and container made of silver-indium-cadmium alloy, generally 80% Ag, 15% In, and 5% Cd

Using these alloys because these can absorb many neutron

without fisioning it

Using prism instead of mirror, because prismhas additional optical capabilities such as

range-finding and targeting

We can use any alloy steel for inner supporting, butfor outer supporting we cant use alloy steel that has

high corrosion. For outer supporting usually coated

by cadmium layer for corrosion protection

Propellers for submarines are made out of

beryllium bronze. It has very interesting physical properties like on

of the highest melting point, flexural rigidity,thermal and acoustic conductions.

The point in submarines propellers is tomanufacture them as thin as possible so that thesubmarine could produce low noise and as strongas possible so that the submarine can achieve

speed.
