HSCR Steel
High Strength Corrosion Resistant Steel for Aerospace Industry

AMD Corp. is currently offering the production technologies and US patents of HSCR steel for sale or licensing.

 Aircraft landing gears and structures have stringent performance requirements. They are subjected to severe loads, corrosion, and adverse
environmental conditions, and have complex shapes which vary in thickness. 300M steel is widely used for high stress aircraft landing gears and structures. This steel is not corrosion-resistant and requires protective coatings. Plating involves using cadmium for corrosion resistance
on external surfaces and chrome for wear resistance on internal surfaces. New restrictions have listed cadmium and chrome coatings as substances of
concern due to the environmental and health risks associated with the manufacturing of cadmium and chrome coatings.
Recently, a new alternative non-toxic zinc-nickel coating is being developed, however, the zinc-nickel coating does not solve the corrosion problem if it cracks. Ultimately, the use of stainless steel provides a more robust solution, reducing maintenance time and cost of repairs caused by corrosion.

High strength corrosion resistant steel (“HSCR steel”) provides the same strength, ductility, and toughness as the 300M steel and while it possesses corrosion resistance in salt spray test.

Table below shows a comparison of room temperature mechanical properties of the vacuum melted and forged bars of HSCR steel after solution
annealing, oil quenching, refrigerating, and tempering and vacuum melted and forged 300M steel after solution annealing, oil quenching, and
tempering.

HSCR steel has showed no rust after the salt spray per ASTM B-117 in 5% NaCl solution at 95°F for more than 200 hrs. Aerospace applications of the
wrought HSCR steel include landing gear components, rotatable shafts, actuators, flap tracks, slat tracks, fasteners, and others.
