MIL-E-19933E (SH)           MIL 309

• ASTM A743, A744 Types CF-8 and CF-3 and ASTM
A240 Type 309S
• For joining carbon or mild alloy steel to austenitic
stainless steels
• Can also be used on “18-8” steels, since it overmatches the
corrosion resistance, if the weldment will not be exposed to
temperatures of 538° C to 927° C (1000° F to 1700° F)
• Ideal for joining stainless steels to themselves or to carbon orlow alloy steels, and can be used at temperatures up to700°F (371°C)
