UNS K92890 — Maraging 250
Marketing general names of alloy: Maraging 250, Vascomax 250. An alloy is manufactured with a help of vacuum-arc or vacuum-inductive smelting. It is a low-carbon nickel-cobalt-molybdenum alloy. Special feature of an alloy is its high flow limit at moderate temperatures (higher than 400°C). Alloy has a high plasticity and weldability at high level of strength. This is one of the nickel family alloys and martensite-ageing steels (in this group Maraging 350 and 300). It can amount up very high tension strength in a temperature range of 430 — 490 °C. Available forms of mill-products: rod, seamless and welded tube, wire, plate, sheet, connecting piece, flange, forging.

Masteralloys produce a multidimensional effect on steels quality:
— nickel increases a plasticity and workability, simplifies a pressure shaping;
— titanium raises a strength counterforce to attack and wipe-out; cobalt increases a heat-resistance, a magnetic permeability;
— molybdenum raises a red-hardness, firmness, resistance to corrosion at high temperatures;
— mangan (that is more than 1%) increases a hardness, resistance to impact load, wearing property;
— titanium raises a stability, a corrosion resistance;
— aluminium increases an oxidation resistance;
— nickel gives not only a plasticity but increases a heat-resistance as well.
Extra-qualitative steel contains borium, zirconium, selenium, nitrogen except for above-said components.
