Monel 400 Round Bars can be supplied in different conditions and dimensions depending on machining, fabrication and component requirements.
Offer greater ductility for applications requiring forming and machining.
Provide increased strength and hardness through controlled deformation.
Feature a smooth, bright surface finish, suitable for precision machining and applications requiring improved dimensional consistency.
Supplied in specified lengths to meet component dimensions and fabrication requirements.
* Availability of each condition, size and finish should be confirmed before ordering.
Engineered for superior resistance in severe chemical and marine environments.
Offers resistance to seawater and many marine service environments, making the alloy useful for selected marine hardware and fluid-handling components.
Performs well in hydrofluoric acid and certain alkaline environments, subject to concentration, temperature, aeration and other process conditions.
Combines useful strength with ductility; cold working can increase strength when the application requires a higher-strength condition.
Can be formed, welded and machined using suitable procedures, with work hardening and tooling requirements considered during manufacturing.
