Maraging 250 and 300 1.6354 1.6358 Ultra High Strength Steel Forgings

Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying Maraging 250 (1.6354) and Maraging 300 (1.6358) open-die forgings, rings and bars to aerospace, defense, space and tooling projects in India and worldwide, from double-vacuum-melted stock.

Why Maraging 250 / 300 for Indian aerospace and tooling projects

Maraging steels are 18%Ni cobalt-molybdenum alloys that reach ultra-high strength (18002000 MPa) by a simple low-temperature age, giving strength with high toughness, weldability and near-zero heat-treat distortion. For India's aerospace, space-launch, defense and high-performance tooling sectors, they suit airframe and structural components, rocket-motor and missile cases, landing gear, and tooling/dies.

Documented capability

Aerospace/defense: airframe and structural components, landing-gear and high-load fittings.

Rocket/missile: rocket-motor, missile and pressure-vessel case sections.

High-performance tooling: cold- and hot-work tooling, dies, mould blocks, extrusion/forging tooling.

Precision high-strength/general: shafts, couplings, drive components; rings, discs, hubs, sleeves, bars, custom forgings.

Product range for Indian buyers

Forged aerospace structural and airframe components; rocket-motor, missile and pressure-vessel case sections; landing-gear and high-load fittings; high-performance cold- and hot-work tooling, dies and mould blocks; precision high-strength shafts, couplings and drive components; rings, discs, hubs, sleeves and bars.
