Final answer:
Solid steel is valuable for making objects more attack resistant due to its strength, hardness, and corrosion resistance. It is used in large structures, like skyscrapers, and for protective purposes, such as in nuclear reactor vessels.
Step-by-step explanation:
To enhance attack resistance, solid steel can be used to reinforce various structural and protective items. Solid steel is a material well-regarded for its strength, hardness, and corrosion resistance, making it an ideal choice for bolstering defenses against physical damage.
Historically, metal alloys like bronze, made primarily of copper with added tin, were utilized for weapons due to their toughness. However, with technological advancements, steel, primarily composed of iron mixed with carbon and various other elements such as chromium, manganese, and nickel, has become the preferred material for many applications needing durability and strength.
Steel alloys, such as stainless steel, are especially effective in attack-resistant applications due to the presence of chromium that forms a protective oxide layer, preventing corrosion. This quality makes steel supreme for large-scale construction like skyscrapers, where a steel skeleton provides the necessary support and durability.
The utilization of solid steel is not limited to large structures alone. For example, a steel shell can protect the reactor vessel in nuclear plants; this typically involves a shell 3-20 centimeters thick that, combined with the moderator, absorbs a significant amount of radiation produced by the reactor.
In conclusion, using solid steel can significantly improve the resilience of an object against attacks, whether in architectural applications or personal protective equipment, thanks to its advantageous properties of strength and corrosion resistance.
