Product Description


High Strength Superelastic Alloy 3J33 Round Steel Impact Resistance


3J33 is a low carbon and high nickel type ultra high strength maraging steel. The properties of the alloy are further improved by adding rare earth cerium. 3J33 has high strength, high elasticity limit, high energy storage ratio, low internal consumption, good toughness, fatigue resistance, stress corrosion resistance, good Impact Resistance, and good thermal stability and processing performance.The alloy has strong magnetic properties and poor corrosion resistance.

High strength and high elastic alloy is an important structural material for Aeronautics industry. In recent years, due to the improvement of composition and performance, more and more elastic components have been used, which has become an indispensable part of elastic materials.

3J33 alloy is also used for making aeronautical structural parts such as pressure vessels, shells, bolts, aircraft landing gear and so on. It is mainly used to make high impact and fatigue resistance elastic sensitive elements, such as spiral joint, diaphragm box, diaphragm, spring, torsion bar and so on, which require good elastic linear relationship under high stress.


We keep stock of 3J33 in round steel and semi-finished materials to meet the customer’s quick delivery needs. In addition, we can provide products that meet the MARAGING (C) 300 | AMS 6514 | ASTM A 538 | UNS K93120 | MIL S 46850 ASTM A579 | SAE AMS 6514 |.
