This info and more on our specialized A193 Microsite. Originally approved in 1936, this specification is heavily utilized in petroleum and chemical construction applications. The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature or high pressure service. ASTM A193 covers a number of other standard specifications not covered in this description including B5, B6, and B16. Grades B7 B8 B8M B8 B8M Alloy steel, AISI 4140/4142 quenched and tempered Class 1 Stainless steel, AISI 304, carbide solution treated. COMMON ASTM FASTENER SPECIFICATIONS FASTENER GRADES INCLUDE: ASTM A193 Grade B7 Chromium Molybendum steel, normally AISI 4140, heat treated to 28-32Rockwell Hardness, 125,000 PSI tensile strength, 105, 000 PSI yield. It will hold it’s strength to 1000 degrees F.

ASTM A193/A193M is a specification from the ASTM International that primarily govern industrial piping applications. In the assembly of an industrial plant, many complex components are bolted together of which include parts such as valves, piping, and pressure vessels. ASTM A193 defines the methodology to procure and certify externally threaded fasteners according to specific chemical and mechanical criteria. It is standards such as this that allow industrial process applications to be safely engineered so they do not exceed the tensile strength of the fasteners that hold them together.^[1]/eeprom-programmer-software.html.

Material grades that are governed under ASTM A193 include: Download lx 300 ii driver.
