A193 is an ASTM (American Society for Testing and Materials) specification, whereas SA193 is from ASME (American Society of Mechanical Engineers). ASME repurposed the ASTM specification. The primary difference is the application.  While both specifications are designed for high temperature / high pressure service, SA193 may also be used in nuclear or other highly critical applications. When used in these critical applications, there may be some additional or supplemental requirements, however in most cases the ASTM and ASME specifications are generally the same.
