Also make sure that the manufacturer has a solid and decent reputation in the industry. It is only right that they should come from reliable manufacturers. Specifications The ASTM A is a specification for stainless or alloy steel bolting materials that are used for industries that involve high temperature. Link to Active This link will always route to the current Active version of the standard.

Most manufacturers also apply coatings to enhance resistance to chemical and corrosive environments. They are used to bolt high temperature environments like valve flanges, heat exchangers, and pressure vessels.

ASTM A Grade Class A/B/C/D Stud Bolts | TorqBolt

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. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Combining values from the two systems may result in non-conformance with the standard. Moreover, A fasteners can also be used for general bolting applications. 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. 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.


Bolts with flattened Panhead with Allen. More importantly, the manufacturer should be knowledgeable of the varying needs and standard requirements of different industries. A is recognized to be ideal for use as industrial fasteners such as bolts, nuts, screws, studs, stud bolts, washers, and bars.

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 be subjected to tension, stress-rupture, and hardness tests. However projects with eastern origin are possible on request. This abstract is a brief summary of the referenced standard.

They may come covered, rolled, or heat treated.

ASTM A453 Grade 660 Bolts

Hardening and solution treatment requirements for each material class are also given. Bolting materials in this specification covers rolled, forged, or hot-extruded awtm, and also bolts, nuts, screws, washers, atm, and stud bolts. These classes allow variations in hardness, temperature resistance, pressure resistance, tension, stress-rupture, yield strength, elongation, and other specifications.


The Supplementary Z453 shall only apply when specified individually by the purchaser in the purchase order or contract. Whether you are looking for manufacturers of collated screws, threaded fasteners, and blind fasteners of every type, Jignesh is the premier source for you. A plays an important role in different applications in major industries worldwide. Previous Post Previous Customized Fabrication.

Our ASTM A Grade Fasteners are widely used in number of industries such as aerospace, defense, automotive, petrochemical, waste processing, marine and pharmaceutical sectors. 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. Because of their excellent temperature ast, A bolting materials are most widely used in industries such as petro-chemical, offshore, power, aerospace, automotive, heavy engineering, and the military.

The yield strength ranges from 50 to ksi.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not satm as part of the standard. Materials shall conform to yield strength, tensile strength, elongation, reduction of area, Brinell hardness, and Rockwell hardness requirements.

The ASTM A is a specification for stainless or alloy steel bolting materials that are used for industries that involve high temperature. Within the text, the SI units are shown in brackets. The material requires special processing and is not intended for general purpose applications. Materials shall adhere to specified contents of carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, tungsten, titanium, columbium, aluminum, vanadium, boron, and copper.
