Mechanical properties of ASTM A508 Class 4 steel used in the LWBR closure head and support flange (LWBR Development Program)
Technical Report
·
OSTI ID:6546067
The LWBR closure head and support flange are manufactured from forgings of ASTM A508 Class 4 steel rather than the ASTM A508 Class 2 forging material more commonly used in reactor vessels and closure heads. Forgings involved were approximately 300,000 pounds and 46,000 pounds. The extensive material test program conducted on ASTM A508 Class 4 LWBR forgings is described. The results of the tests confirm that the A508 Class 4 material used for the LWBR forgings has been quite good through thickness, fracture toughness, and strength properties and fully meet all specified requirements.
