ASTM A193
Scope
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 service. This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material is often available in national coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8 threads per inch (tpi) for diameters above one inch.
Below is a basic summary of a few of the common grades. ASTM A193 covers a number of other standard specifications not covered in this description including B5, B6, and B16.

Recorded on February 9, 2011, this was the fifth webinar in the “Achieving Excellence and Innovation in Family, School, and Community Engagement” (FSCE) series.
Strategic community partnerships are a key component of systemic family, school, and community engagement in education. These partnerships draw on the strengths of community groups as they surround students with an array of supports to enhance learning and prepare them for the 21st century. Strategic partnerships also create a culture of communication with each other and with families and schools to ensure the services they provide meet the needs of their communities.
This webinar examined practical examples of how to build successful strategic partnerships that foster community engagement, including how to select the organizations, people, and services to be included; how to structure communications to ensure ongoing collaboration; and how to build connections with families and schools.
You will hear from a Promise Neighborhood grantee about the program’s vision and how it is forming partnerships to support students from birth through college and career preparation, from The Children’s Aid Society about why the community school model promotes strong families and successful students, and from the United Way of Lake County, Illinois about a community engagement planning process to ensure on-time high school graduation. The U.S. Department of Education’s Center for Faith-based and Neighborhood Partnerships will also speak about what the initiative is doing to sponsor deliberate and ongoing partnerships.
Presenters include:
– Moderator: Lindsay Torrico, Manager, Public Policy, United Way Worldwide
– Reverend Brenda Girton-Mitchell, Director, Center for Faith-based and Neighborhood Partnerships, U.S. Department of Education
– Jane Quinn, Director, National Center for Community Schools, The Children’s Aid Society
– Irasema Salcido, Founder, Cesar Chavez Public Charter Schools for Public Policy, Promise Neighborhood Grantee
– Helen Westmoreland, Director of Program Quality, Flamboyan Foundation
– Michelle Mittler Crombie, Vice President of Community Development, United Way of Lake County, Illinois
