Revision of B705-17 Standard Specification for Nickel-Alloy (UNS N06625, N06219 and N08825) Welded Pipe

Keywords

None Provided

Rationale

Mechanical properties in B705 Table 2 for N06625 Grade 1 are based on properties of cold rolled sheet produced to B443 N06625 Grade 1 with minimum tensile and yield strengths of 120,000 and 60,000 psi. There is no allowance for pipe made from hot rolled plate produced from B443. This revision adds a line to Table 2 to reflect the lower minimum tensile and yield strength of 110,000 psi and 55,000 psi when pipe is produced from hot rolled plate to produce heavier wall thickness. This change eliminates the need to screen available plate to insure the higher properties are met.
