Furthermore, Co and Ti contents influence strongly the precipitation. The lattice diffusion mechanism in the martensite reversion is influenced by Ni and Co contents and heating rate. For small heating rates ( ~1 °C/s) this mechanism prevails in the 300 maraging steel while for the 350 maraging steel has a minor importance.

Maraging steel is strong, tough, low-carbon martensitic steel which contains hard precipitate particles formed by thermal ageing. The term maraging is derived from the combination of the words martensite and age-hardening. Maraging steel contains an extremely low amount of carbon (0.03% maximum) and a large amount of nickel (1719% Maraging steel - EP2671955A1 PatentGuruThe present invention provides a maraging steel containing:0.10C0.30 mass%, 6.0Ni9.4 mass%, 11.0Co20.0 mass%, 1.0Mo6.0 mass%, 2.0Cr6.0 mass%, 0.5Al1.3 mass%, and Ti0.1 mass%, with the balance being Fe and unavoidable impurities, and satisfying 1.00A1.08, in which A is 0.95+0.35×[C]-0.0092×[Ni]+0.011×[Co]-0.02[Cr]-0.001×[Mo], where [C] indicates
Translate this pageMaraging-Stähle (von englisch martensite + aging = martensitaushärtbar) sind eine Gruppe hochfester Stähle, die für eine gleichzeitig gute Zähigkeit bekannt sind.Die nahezu kohlenstofffreien Legierungen sind mit einem hohen Anteil Nickel (>12 %) legiert und werden einer besonderen Wärmebehandlung unterzogen, die technisch gesehen dem Vergüten entspricht. Microstructural Analysis of Co-Free Maraging Steel Aged(2002) observed that the heat treatment at 470°C performed in a maraging steel with 18%wt. Ni, after forging, has achieved a 90% increase in hardness, with only 15 min of aging. In the detail of Fig. 1, it is observed that the maximum hardness is obtained at 550°C/60 min for both ARs. On the other hand, the thermal aging at 550°C exhibits a

Steels - Endurance Limits and Fatigue Stress1 MPa = 10 6 Pa = 1 N/mm 2 = 145.0 psi (lbf/in 2); Fatigue limit, endurance limit, and fatigue strength are used to describe the amplitude (or range) of cyclic stress that can be applied to the material without causing fatigue failure.; Creep. The time dependent deformation due to heavy load over time is known as creep.. In general both stress and temperature influence on the rate of creep

Access securities related information for Canadian companies. maraging, nanoprecipitates, TWIP, TRIP, AHSS,stainless Maraging steel 250 is an 18 wt.% nickel steel that has been strengthened with cobalt. Maraging 250, like all maraging steels, goes through an aging process that forces the metal to cool from its molten state to its solid state over an artificially long time. This process results in tempered steel that has both high levels of strength and hardness.
The evolution of precipitates in maraging steel of grade 350 was studied using the complementary techniques of small angle X-ray scattering (SAXS) and transmission electron microscopy (TEM). These investigations revealed that ageing the steel at 703 K involved a rhombohedral distortion of the supersaturated b.c.c. martensite accompanied by the appearance of diffuse -like structures.
