E308

Germany SG X5 Cr Ni 19.9ISO 23.12

UNS W30940

C 0.08Mn 1 - 2.5Si 0.25-0.6Ni 9-11Cr 19.5-22

Thyssen-Therm JKobe-MGSLincoln L18.8Pacweld -PW176SSSanvik 19.9

E308 is typically used when the corrosive conditions are not severe

E308L(low

carbon)

Germany SG X2 Cr Ni 19.9

ISO 119.9L

UNS W30843

C 0.03Mn 1 - 2.5Si 0.25-0.6Ni 9-11Cr 19.5-22

ESAB -OK 16.10Thyssen -JESandvik 19.9L

Note (L).The lower carbon is used to avert the formation of carbide precipitation

308LSi    

ESAB- OK 16.12Thyssen - JESiSandvik 19.9LSiFilarc - PZ6061/6561TREFIL 2PPSG

Note Si or Hi Si. The high silicon can increase arc stability and the weld wetting, which is important for some the low amp, sluggish, short circuit welds

309

Germany SG X12 Cr Ni 22.12

ISO 23.12

UNS W30940

C 0.012Mn 1 - 2.5Si 0.25-0.6Ni 12-14Cr 23-25

ESAB- OK 16.53Sandvik- 24.13Thyssen -Therm 25.14

Used for welding 309 and austenitic to ferritic (carbon) steels

309L  

C 0.03Mn 1 - 2.5SI 0.25-0.6Ni 12-14Cr 23-25

 Used for weld overlay applications or butter passes.

310H  C 0.10 -0.12Cr 26Ni 22

 

(H) Has minimum carbon content lower carbon can cause micro cracking causing tensile reductions

310

Germany SG X12CrNi 25.20

ISO 25.20

UNS W31040

C 0.08-0.15Mn 1 - 2.5Si 0.25-0.6Ni 20-22.5Cr 25-28

 To weld 310 and 304 clad and stainless overlay

For low or high temp, corrosive or any critical applications always confirm electrode choice with

wire manufacturer.Using ELC ensure weld gas has less than 3% CO2. A

low co2 mix is less oxidizing than a low oxygen mix.For low carbon base use low carbon filler

312

Germany SG 9250XRCUNS W31240ISO 29.9

C 0.15Mn 1 - 2.5Si 0.25-0.6Ni 8-10Cr 28-32

 Higher Ferrite.More "crack resistance" than E309.

ESAB- 16.35Thyssen - Therm G.Sandvik 19.12.2

for 316 steels and good for "high temp" corrosion resistance

316L

Germany SG X2 CrNiMo 19.12ISO 19.12.2LUNS W31643

C 0.03Mn 1 - 2.5Si 0.25-0.6Ni 11-14Cr 18-20Mo 2-3

317L UNS 31743

C 0.03Mn 1 - 2.5Si 0.3-0.65Ni 13-15Cr 18.5-20.5Mo 3-4

 

Has moly to increase the tensile strength. Has excellent corrosion resistance and high temp properties Note contains considerable ferrite which can lower toughness properties.
