The key to the P5 composition of chromium-molybdenum alloys is the addition of chromium and molybdenum. Chromium or chromium increases high temperature strength, increases oxidation resistance and increases tensile, yield and hardness at room temperature. Molybdenum improves strength, elastic limit, wear resistance, impact quality and hardenability. It increases resistance to softening, inhibits grain growth, and makes chrome steel less susceptible to embrittlement. Molybdenum is also the most effective additive for increasing high temperature creep strength or creep resistance. It also enhances the corrosion resistance of the steel and inhibits pitting corrosion.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

INCONEL? alloy 718 (UNS N07718/W.Nr. 2.4668) is a high-strength, corrosion-resistant nickel chromium material used at -423¡ã to 1300¡ãF. Inconel alloys are resistant to oxidation and have the ability to maintain its structural integrity in high temperature atmospheres.
