Why does Sandvik use ferritic stainless steel in welding?
See Sandvik Welding Guidelines for more specific information. Ferritic stainless steel alloys, by their nature, tend to weld sluggishly due to their poor flow characteristics. Sandvik has developed special chemistries for several grades of ferritic stainless steels to improve this condition.See all results for this questionWhy are ferritic stainless steel alloys so slow to weld?Ferritic stainless steel alloys, by their nature, tend to weld sluggishly due to their poor flow characteristics.

Contact Sandvik for more information.See all results for this questionWhat kind of filler is used for arc welding?Higher strength fillers of the AWS EniCrMo-3 (alloy 625) type are now readily available and these enable all the arc welding processes to be used. They also match parent metals with respect to toughness and ultimate tensile strength although the 0.2% proof strength of TIG, MIG and SAW weld metals may fall below that specified for the 9%Ni steel.See all results for this question
Welding of Steels :: Total Materia Article
The low-alloy high-strength steels represent the bulk of the remaining steels in the AISI designation system. These steels are welded with E-80XX, E-90XX, and E-100XX class of covered welding electrodes. It is also for these types of steels that the suffix to the electrode classification number is used. These steels include the low-manganese steels, the low-to-medium nickel steels, the low nickel-chromium steels, the molybdenum steels, the chromium-molybdenum steels, and the nickel-chromiuSee more on totalmateria ferritic chrome steel Submerged arc weldingWelding of Ferritic Cryogenic Steels - TWIMatching C/Mn composition metal active gas (MAG), flux cored (FCAW) and submerged arc (SA) consumables will not give adequate toughness at -50°C and require nickel to provide the required as-welded toughness. This is generally limited to a maximum of 1%Ni to comply with the NACE International ISO15156-2/MR0175 requirement for use in sour service.Welding guide Sandvik Materials TechnologyWelding of Ferritic Steels Ferritic stainless steel alloys, by their nature, tend to weld sluggishly due to their poor flow characteristics.

Stainless Steels - Lincoln Electric
non-standard ferritic stainless steels. They are characterized by weld and HAZ grain growth which can result in low toughness of welds. To weld the ferritic stainless steels, filler metals should be used which match or exceed the Cr level of the base alloy. Type 409 is available as metal cored wire and Type 430 is available in all forms. AusteniticStainless Steel | Alloys InternationalAI-1607 is a submerged arc cored austenitic alloy for welding 14% Mn steels, armour steels, hardfaced wear plate, hardening steels, and generally all difficult to weld steels. Use AI-1607 for welding and surfacing of rails, depositing 1st layer before hardfacing on 14% Mn steels or on steels Stainless Steel Welding | Unique WeldingWhen welding with submerged arc welding, the choice of flux has an influence on the amount of Chromium that will be retained in the weld. High silica fluxes can lose up to 5% of the chromium content of the wire. Some fluxes will add carbon which will also reduce the ferrite content to near zero.
