When the carbon content in the alloy is 0.05 to 0.309%, it is considered as the mild carbon steel. Maraging steels are a class of high-strength steel with low C content and the use of substitutional (as opposed to interstitial) elements to produce hardening from formation of Ni martensites. The chemical composition was derived by combustion-infrared absorbance and is mentioned in Table 1. AISI 304 is also commonly known as 18/8 steel as it contains 18% chromium and 8% nickel. This makes metals inherently tougher than hard, brittle materials because in all that bond-breaking and bond-making, energy is consumed; it takes a great deal of energy to. Estimate the resilience, d). On the other hand, in the case of the maraging steel substrate, the restitution coefficient is markedly affected by the friction at a particular test condition, although there is little influence under conditions where the coating is thick enough to obtain the restitution coefficient of the coating. Of special practical value is the fact that particles of intermediate intermetallics in maraging steels are extremely disperse, which is mainly due to their precipitation at dislocations. Where fracture toughness and impact strength are crucial, 300M is a great choice. AISI/SAE 4340 Alloy Steel, 4340, is a nickel-chromium-molybdenum alloy steel known for its toughness and its ability to attain high strengths in the heat-treated condition.
