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 of each heat, also, all forged or rolled hardenability test specimens must be normalized prior to testing. Parts for handling acetic, nitric, and citric acids, organic and inorganic chemicals, dyestuffs, crude and refined oils, etc.
It is a3044 only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. It is also widely used for architectural trim. This specification covers carbon and alloy steel bars subject to end-quench hardenability requirements. Lead is generally reported as a range of 0.

The end-quench hardenability shall conform to the requirements specified on the purchase order.
ASTM A304 / 304 L:
The fine austenitic grain size requirements of the steel material are presented in details. About Us Contact Us Thierry Boehm Photos and Videos By: Both hardness and tensile strength can be increased by cold working, which may cause slight magnetism. The resultant weld has good toughness and ductility.
It is good in corrosive environments as in paper and chemical industries and cryogenic services and used where corrosion resistance and good mechanical properties are primary requirements. Although we believe the information to be corrrect, Metal Stock, Inc.
The grain size and end-quench hardenability test methods are presented in details. Annealing is recommended after forging to maintain maximum corrosion resistance.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is non-magnetic in the annealed condition and not hardenable by heat treatment.
ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
ASTM A304 Grade 4140H
Cold working increases tensile strength and hardness. Special hardenability limits are also permissible when approved by the purchaser and manufacturer. Click the button below. Water should be used for heavier sections; air for lighter sections.
The heat analysis shall conform to the requirements as to chemical composition. It is easily welded by all commercial processes except forge or hammer welding.
