HSCR Steel vs Titanium Alloy

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

HSCR steel is a suitable material for manufacturing of the high-stressed aircraft landing gear components and gas turbine components such as disks, impellers, shafts, and other with elevated temperature up to 950F.

Aircraft landing gear components and gas turbine components (“components”) can be manufactured from HSCR steel powder by Hot Isostatic Pressing (HIP) followed by machining and hardening.
Formation of near net shape (NNS) by HIP allows manufacturing of the various types of the complex shape components. The process supplies precise geometry of the articles and properties that are close to the properties of the forgings.
The cost of HIP articles is generally higher than the cost of the forged articles; however small batches of the large section articles are economically feasible to produce by HIP rather than forging of the melted ingots. Manufacturing of the aircraft components by HIP from HSCR steel powder allows achieving high quality products at a reasonable cost.

Additive manufacturing (AM) followed by finish machining and annealing is another method of manufacturing of the aircraft components from HSCR steel powder. AM has the lowest “buy-to-fly” ratio (“a ratio the mass of raw material to the mass of the product”) among other methods of manufacturing.

Table below shows the ASTM standard mechanical properties of HSCR steel and Ti-6Al-4V alloy made by two different manufacturing processes:
- PM HIP + Hardening - consolidated by HIP of HSCR steel powder hardened by quenching, refrigerating, and tempering (“QRT”) and Ti-6Al-4V alloy powder hardened by solution treating & aging (“STA”)
- Selective Laser Melting (SLM) + Annealing - built by SLM of HSCR steel powder and Ti-6Al-4V alloy powder followed by annealing.

HSCR steel has the following advantages compared to Ti-6Al-4V alloy:
-Higher specific strength and stiffness
-Higher strength at elevated temperatures
-Better workability and machinability.
The aircraft components manufactured by HIP and SLM from HSCR steel powder have more than 20% cost reduction compared to the same weight components manufactured by the same processes from Ti-6Al-4V alloy powder.

HSCR steel powder allows substituting Ti-6Al-4V alloy powder for manufacturing of the same weight components without sacrificing stiffness, durability, and lifetime.
Also, HSCR steel reduces the titanium dependency of the aircraft manufacturers from the monopoly of suppliers of titanium on the world market.
