Notes: a. Where (-G) designation is used in the classification, chemical composition of the filler metal shall be as agreed to by purchaser and

supplier. In this example, it is as follows: (Some Users Request: “Meets the mechanical requirements of E9015-B 9“, instead of using the “-G designator).

C 0.07-0.13% Cr 8.00-9.50% Ti <0.004% Cu <0.20% Mn 1.25% max. Ni 1.00% max. As <80ppm N2 0.03-0.07% Si* 0.20-0.50% Mo 0.80-1.10% Sb <30ppm Other <0.50% Total S* <0.010% Nb 0.02-0.10% Sn <30ppm P* <0.010% V 0.15-0.25% Al <0.04% *FCAW: Si = 0.50% max., S = 0.015% max., P = 0.020% max.

See the applicable Welding Procedure Specification (WPS) or contact the applicable Corporate Welding Engineer in Construction Technology for the approved manufacturers and brand names of FCAW filler metals.

b. Either H4 or H8 Diffusible Hydrogen Designator is acceptable; however, H4 is preferred. The Optional Diffusible Hydrogen Designator indicates that the diffusible hydrogen in the deposited weld did not exceed either 4.0 mL/100g (H4) or 8.0 mL/100g (H8) when tested in accordance with AWS A4.3 and A5.5 specifications.

c. X-Factor (Bruscato Number) can be calculated using the following formula: where, X = (10P+5Sb+4Sn+As)/100, elements may be expressed in either % or ppm.

d. Welding filler metal shall be purchased with CMTR (Certified Material Test Reports), for domestic manufactures or EN10204 – “3.1b” for European manufacturers.
