Welding 347 filler metal into a Nickel base filler metal is almost guaranteed to hot crack in the first pass against the nickel base filler. As a general rule of thumb, never weld stainless filler into nickel base filler weld nickel base filler into the stainless steel. REWelding 3" Thick 347 SS to Carbon Steel


Detailed

The high temperature oxidation resistance of 347 is similar to that of 304 stainless steel. Useful to 1500°F. Often in many product forms, the grain size and carbon content can meet both the 347S and 347H requirements. Appropriate weld fillers are AWS ER347 bare wire and E347 covered electrodes.


Detailed

The lower carbon content is ideal for applications that have a risk of intergranular corrosion cracking. The higher silicon content serves as a deoxidizer and helps remove weld impurities and increase weld puddle fluidity. Because you are welding carbon steel to SS, be some weld dilution from the sides of

Corrosion Resistance. Alloy 347 stainless steel plate exhibits good general corrosion resistance that is comparable to 304. It was developed for use in the chromium carbide precipitation range of 800 – 1500°F (427 – 816°C) where un stabilized alloys such as 304 are subject to intergranular attack.

May 09, 2017 · Carbon Content. Low carbon steel is typically the most readily welded steel in a room temperature environment. Examples of low carbon steel suitable for welding include C1008, C1018, A36, A1011 and A500. Medium carbon steel such as C1045 typically requires preheat and post heat treatment to avoid weld cracking.


Detailed

309 is usually the filler metal chosen for welding stainless to carbon steel when the composition of both are known. Nickel alloys are sometimes used for welding stainless to carbon because nickel alloys wont become hard and brittle no matter the carbon content of the steel. The base metal can become hard but the weld metal wont.


Detailed

Carbon Steel to Stainless Steel. carbon to SS I've done a fair amount of carbon to stainless, primarily 304, but also a bit of 316l, in precipitators and associated assemblies. Carbon to 304 is easy enough with 309, and doable with 308 as well, but remember that the


Detailed

Welding consumables must also be selected with low carbon content if best corrosion resistance is required. Most arc welding consumables contain less than 0.03% carbon but there are filler metals available with carbon contents of up to 0.10%; these should only be used to weld the 'H' grades of steel where good creep resistance is required.


Detailed

Use 309L (including ER309LSi) when joining mild steel or low alloy steel to stainless steels, for joining dissimilar stainless steels such as 409 to itself or to 304L stainless, as well as for joining 309 base metal. CG 12 is the cast equivalent of 309.


Detailed

Joint preparation for carbon steel is the same as if you are stick welding with an E7018. The weld area needs to be free of oils, paints, heavy rust, and in most cases mill scale. The weld area needs to be free of oils, paints, heavy rust, and in most cases mill scale.

Swanton Welding was asked to fabricate two furnace shells made of A36 Carbon Steel and 304L Stainless Steel. We have worked with this customer previously, and they are well aware of our large fabrication capabilities and the advanced welding ability of our team.

Typical chemical composition of the weld metal isCarbon 0.025% Chromium 19.7% Nickel 12.5% Manganese 1.3% Silicon 0.6% Molybdenum 2.2% 5. 17. 6 Core Bright 347 (AWS E347LTo 3) This electrode is used to weld types 347, 304L, and 321 stainless steels where the maximum corrosion resistance is required.

Jan 17, 2015 · 330 SS to carbon steel. I am welding 330 SS to carbon steel and the customer said they welded the butt weld joint with 309 in the past. Having never welded 330 before I started doing some research. From what I have found 309 used as a filler will/can crack and the


Detailed

You have to isolate the weld from the carbon in the steel. Typically you would butter the CS with Ni 82. Then weld together with C276 filler. The 309 has significant thermal expansion mismatch (which can cause hot tearing). Use the correct filler. = = = = = = = = = =


Detailed

May 03, 2014 · Stainless steel family includes three types; austenitic, martensitic and ferritic. Austenitic stainless steel is known for best welding properties and excellent corrosion resistance. It has face centered cubic structure with the alloying elements of chromium, nickel, manganese, carbon, nitrogen, chromium, molybdenum.


Detailed

Failed Stainless Pipe Weld Tests. If while welding the carbon steel pipe root, the welder uses higher current, slower weld speeds or a wider weld weave, the 309L weld can end up with more weld dilution with the carbon steels, reducing the weld ferrite level and making the weld more austenitic.
