Ultra-Strength Steel

Martensitic Aging Steel: 

Martensitic aging steel is characterized by its high purity and strength, good plasticity and toughness and especially high yield strength and fracture toughness with yield strength ratio over 95 percent. The heat treatment process is simple, no carburization can be achieved, deformation after quenching can be controlled to small extent, and cold forming as well as machinability is rather good. The steel can be made into large load-bearing parts, parts and components, pressure-resisting shells, power rotating shafts, high-pressure vessels, moulds, springs and deep-punching parts. 

High-alloy Ultra-high Strength Steel:

High-alloy ultra-high strength steel is characterized by its ultra high strength and toughness. 16Co 14Ni 1 0Cr 2MoE steel can be made into shafts, large bolts etc. 
9Ni-4C o series of steel can be widely made into pressure resistance shell, bear force structure parts, armor plates, high pressure vessel etc.
