This standard is issued under the fixed designation A ; the number immediately following the analysis required, ASTM A , dated ______, worm gear. Buy ASTM A SPECIFICATION FOR CARBON AND ALLOY STEEL BARS SUBJECT TO END-QUENCH HARDENABILITY REQUIREMENTS from SAI. ASTM A Standard Specification for Carbon and Alloy Steel Bars Subject to End-Quench Hardenability Requirements.
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. The heat analysis shall conform to the requirements as to chemical composition. It is a good general all-purpose stainless grade. This specification covers carbon and alloy steel bars subject to end-quench hardenability requirements.
It is informational 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. Lead is generally reported as a range of 0.
Annealing is recommended after forging to maintain maximum corrosion resistance. No other units of measurement are included in this standard. 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. Parts for handling acetic, nitric, and citric acids, organic and inorganic chemicals, dyestuffs, crude and refined oils, etc.
Check out our inventory of steel tubing and piping. It is non-magnetic in the annealed condition a340 not hardenable by heat treatment.
ASTM A304 – 16
The content of this material specification page was compiled from available public sources and authorities on material properties. The end-quench hardenability shall conform to the requirements specified on the purchase order.

It is easily welded by all commercial qstm except forge or hammer welding. Thierry Boehm Photos and Videos By: About Us Contact Us It is also widely used for architectural trim.
Monday – Friday 8: Although we believe the information to be corrrect, Metal Stock, Inc. The fine austenitic grain size requirements of the steel material are presented in details.
ASTM A304 / 304 L:
Both hardness and tensile strength can be increased by cold working, which may cause slight magnetism. Water should be used for heavier sections; air for lighter sections. Link to Active This link will always route to the current Active version of the standard. Historical Version s – view previous versions of standard. 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.
The grain size and end-quench hardenability test methods are presented in details. Click the button below. Cold working increases tensile strength and hardness.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Special hardenability limits are also permissible when approved by the purchaser and manufacturer.
Metal Stock, Inc. – Stainless Steel ASTM A / L Info.
Method A is the minimum and maximum hardness values at any desired distance, Method B is the minimum and maximum distances at which any desired hardness value occurs, Method C is the two asstm hardness values at two desired distances, Method D is the two minimum hardness values at two desired distances, and Method E is any minimum hardness plus any maximum hardness.
The methods for estimating the hardness value of the material are presented. This abstract is a a04 summary of the referenced standard. The resultant weld has good toughness and ductility.
We carry seamless and welded stainless steel and carbon steel pipe. Need A Quick Quote? Because of its lack of magnetism, it is highly desirable for instruments.
