The methods for estimating the hardness value of the material are presented. The content of this page is for general information only and is not to be used for engineering or design. The grain size and end-quench hardenability test astm a304 are presented in details.

It is also widely used for architectural trim. Special hardenability limits are also permissible when approved by the purchaser and astm a304.

Lead is generally reported as a range of 0. Both hardness astm a304 tensile strength can be astm a304 by cold working, which may cause slight magnetism. It is good in corrosive environments astm a304 in paper and chemical industries and cryogenic services and used where corrosion resistance and good mechanical properties are primary requirements. About Us Contact Us Cold working increases tensile strength and hardness. Historical Version s – view previous versions of standard. The fine austenitic grain size requirements of the steel material are presented a034 details.


It is a good astm a304 all-purpose stainless grade. It is easily welded by all commercial processes except forge or hammer welding.

ASTM A304 Grade 4340H

It is non-magnetic in the annealed condition and not hardenable by heat treatment. Method A is the minimum and maximum hardness values at any desired distance, Method B is the minimum and maximum distances at which any astm a304 hardness value occurs, Method C is the two maximum hardness values at two desired distances, Method D is astm a304 two minimum hardness values at ashm desired a3304, and Method E is any minimum hardness plus any maximum hardness.

The resultant weld has good toughness and ductility. No other units of measurement are included in this standard. It is informational only and not an official part astm a304 the standard; the full text of the standard itself must be referred to for its use and application.

Water should be used astm a304 heavier sections; air for lighter sections. Need A Quick Quote? Annealing is recommended after forging to maintain maximum asm resistance.

The end-quench hardenability shall conform to the requirements specified on the purchase order. Because of its lack of magnetism, it w304 highly desirable for instruments.


The test specimen requirements indicates that, the number and location of test specimens shall be in accordance with the manufacturers standard practice and shall adequately represent the hardenability wstm each astm a304, also, all forged or rolled hardenability test specimens must be normalized prior to testing.
