A low corrosion rate in rapidly flowing seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters, and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions. Monel Round Bars have high strength properties, heat treatable, good corrosion resistance, formability and weldability.
Examples of such requirements include, but are not limited to, the following: The rod shall then be rotated slowly against the indicator, and the deviation from straightness in any portion of the rod between the supports shall not exceed the permissible variations prescribed in Table Longitudinal strip specimens shall be prepared in accordance with Test Methods E 8 for rectangular bar up to 1? Your comments are invited either for revision of this standard or for additional standards and should b1664 addressed to ASTM International Headquarters.

The distance between the jaws of the testing machine, with the specimen in place ready for testing, shall be not less than 10 in. One test per lot shall be performed for chemical analysis, tension test, hardness test, and wrapping test.
The material shall conform to the chemical composition limits specified by the reference material. Good resistance to sulfuric and hydrofluoric acids. The alloy has been used in a variety of applications. It is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. Our entire round bar inventory is available in random lengths or can be cut to specific lengths to meet your exact requirements. One test per lot shall be performed for chemical analysis, tension test, hardness test, and wrapping test.
