Welding Stainless Steel to Carbon Steel
Welding of austenitic stainless steel and carbon steel base metal should use a filler metal that prevents solidification cracking. 309 is the preferred filler metal as it provides ferrite number of at least 3.

How Carbon Content Affects the Weldability of Steels
And its effects on strength, hardness, ductility and machinability
Steel is an alloy of iron and carbon along with several other elements in small quantities, all of which have an impact on its properties. Steels can contain varying amounts of carbon and are typically categorized as low, medium or high carbon steels. Low carbon steels are those containing 0.30% carbon or less. Medium carbon […]
The Importance of the Heat Affected Zone (HAZ)
When we weld we generate enough heat in the welding arc to melt the filler metal and base material. Or just the base material is we are welding autogenously (as in GTAW without filler). The edges of the base material melt and combine with the filler metal to create what is called the composite zone. […]
