See current steel prices or today's $/lb reference for common alloys
Maraging steel (350 KSI tensile). The top of the maraging family. Maximum strength achievable in a commercially available steel. Same ease of machining in the annealed condition as 250 and 300 grades. Extremely rare and expensive. Reserved for the most demanding applications where no other material will do. Compare to Maraging 300 (slightly lower strength, more available) and custom precipitation-hardening alloys.
