1.4301 stainless steel grade offers excellent corrosion resistance in many environments. It offers moderate resistance to pitting and crevice corrosion. In more corrosive environments, such as chemical or marine, a higher quality stainless grade such as 1.4401 may be better suited.

Stainless steel 1.4301 is readily weldable with common welding procedures. Lower carbon 1.4307 is a better option if welding is required. Post weld annealing is not normally required, except for service in more extreme conditions. We recommend you contact your welding consumables supplier who should provide you full assistance and information on welding stainless steel.

Heat the 1.4301 steel slowly and uniformly throughout the section to 1150-1250°C. Re heat as necessary and avoid working below 900°C. Cool in air. Forgings will require annealing in order to obtain optimum corrosion resistance.

The oxidation resistance of a stainless steel grade is traditionally termed as the scaling temperature. This is the temperature at which the oxidation rate of the steel becomes unacceptably high. The safe scaling temperature for continuous service of 1.4301 is 875°C. In an oxidising and reducing sulphurous atmosphere the scaling temperature is lowered.
