The ASTM A is a specification for stainless or alloy steel bolting materials that are used for industries that involve high temperature.

However projects with eastern origin are possible on request. Next Post Next Eye Aa453. Specifications The ASTM A is a specification for stainless or alloy steel bolting materials that are used for industries that involve high temperature. It is only right that they should come from reliable manufacturers. Depending on the classes, ASTM A materials contain specified amounts of several elements such as carbon, silicon, nickel, chromium, molybdenum, titanium, columbium, aluminum, vanadium tungsten, boron, manganese, phosphorus, sulfur and copper.

Link to Active This link will always route to the current Active version of the standard.

When purchasing this type of material, you should ensure that you select a manufacturer that offers a wide range of high standard products.

Materials shall conform to yield strength, tensile strength, elongation, reduction of area, Brinell hardness, and Rockwell hardness requirements.

Most manufacturers also apply coatings a543 enhance resistance to chemical and corrosive environments. The Supplementary Requirements shall only apply when specified individually by the purchaser in the purchase order or contract. The yield strength ranges from 50 to ksi. Work Item s – proposed revisions of this standard. More importantly, the manufacturer should be knowledgeable of the varying needs and standard requirements of different industries. Materials shall be subjected to tension, stress-rupture, and hardness tests.

Bolts with flattened Panhead with Allen. They may come covered, rolled, or heat treated. 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.

Moreover, A fasteners can also be used for general bolting applications. A is recognized to be ideal for use as industrial fasteners such as bolts, nuts, screws, studs, stud bolts, washers, and bars. Also make sure that the manufacturer has a solid and decent reputation in the industry. Bolting materials in this specification covers rolled, forged, or hot-extruded bars, and also bolts, nuts, screws, washers, studs, and stud bolts.

Combining values from the two systems may result in non-conformance with the standard. Our ASTM A Grade Fasteners are widely used in number of industries such as aerospace, defense, automotive, petrochemical, waste processing, marine and pharmaceutical sectors.


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. This abstract is a brief summary of the referenced standard. Whether you are looking for manufacturers of collated screws, threaded fasteners, and blind fasteners of every type, Jignesh is the premier source for you.

These classes allow variations in hardness, temperature resistance, pressure resistance, tension, stress-rupture, yield strength, elongation, and other specifications.

They are used to bolt high temperature environments like valve flanges, heat exchangers, and pressure vessels. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

They should be able to provide excellent customer service, guarantee high standard products at competitive prices, as well as provide fast shipping and secure payment options.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Hardening and solution treatment requirements for each material class are also given. A plays an important role in different applications in major industries worldwide. Within the text, the SI units are shown in brackets.

Materials shall adhere to specified contents of carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, tungsten, titanium, columbium, aluminum, vanadium, boron, and copper.
