AISI 4161 Springs
AISI 4161 has high strength, resistance to intergranular corrosion and chloride stress corrosion. They have very high fatigue strength that helps to improve the lifetime of the material. They also have enough toughness and plasticity, in case of sudden brittle fracture under the action of a force
