Form	Condition	Rm MPa	Rp0.2 MPa	A ≥ %	Other requirements and notes
Sintered blanks and parts (accepted on sintered test bars)	Class 2 (nominal W 92.5 %)	≥ 758 (110 ksi)	≥ 517 (75 ksi)	≥ 5	Also specified: Hardness ≤ 33 HRC Density 17.15–17.85 g/cm³. The hardness cap applies to as-sintered or annealed material; worked or strain-aged material can reach 49 HRC. B777 has four classes (90, 92.5, 95 and 97 % W) and no 93 % class; the two closest to 93W are listed.
Sintered blanks and parts (accepted on sintered test bars)	Class 3 (nominal W 95 %)	≥ 724 (105 ksi)	≥ 517 (75 ksi)	≥ 3	Also specified: Hardness ≤ 34 HRC Density 17.75–18.35 g/cm³. The hardness cap applies to as-sintered or annealed material; worked or strain-aged material can reach 49 HRC. B777 has four classes (90, 92.5, 95 and 97 % W) and no 93 % class; the two closest to 93W are listed.
