Moreover, A fasteners can also be used for general bolting applications. Within the text, the SI units are shown in brackets. More importantly, the manufacturer should be knowledgeable of the varying needs and standard requirements sstm different industries.

A is recognized to be ideal for use as industrial fasteners such as bolts, nuts, screws, studs, stud bolts, washers, and bars. Also asfm sure that the manufacturer has a solid and decent reputation in the industry.

They are used to bolt a45 temperature environments like valve flanges, heat exchangers, and pressure vessels. Because of their excellent temperature resistance, A bolting materials are most widely used in industries such as petro-chemical, offshore, power, aerospace, automotive, heavy engineering, and the military.

Specifications The ASTM A is a specification for stainless or alloy steel bolting materials that are used for industries that involve high temperature. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The Supplementary Requirements shall only apply when specified individually by the purchaser in the purchase order or contract.


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 asgm, and Rockwell hardness requirements.

Hardening and solution treatment requirements for each material class are also given. Next Post Next Eye Bolts. Historical Version s – view previous versions of standard. Materials shall be subjected to tension, stress-rupture, and hardness tests.

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. It is only right that they should come from reliable manufacturers.

These classes allow variations in hardness, temperature resistance, pressure resistance, tension, stress-rupture, yield strength, elongation, and other specifications. However projects with eastern a45 are possible on request. Work Item s – proposed revisions of this standard. Bolting materials in this specification covers rolled, forged, or hot-extruded bars, and also bolts, nuts, screws, washers, studs, and stud bolts.

The material requires special processing and is not intended for general purpose applications. 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 ASTM A is a specification for stainless or qstm steel bolting materials that are used for industries that involve high temperature.

Bolts with flattened Panhead with Allen. A plays an important role in different applications in major industries worldwide. They may come covered, rolled, or heat treated.

Our ASTM A Grade Fasteners are widely used in number of industries such as aerospace, defense, automotive, petrochemical, waste processing, marine and pharmaceutical sectors. Most manufacturers also apply coatings to enhance resistance to chemical and corrosive environments.

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

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. Combining values from the two systems may result in non-conformance with the standard. 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 provided as part of the 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.

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.
