Steel resistance to corrosion.

Resistant to:

- atmospheric corrosion,

- natural waters (with the exception of sea and pit water),

- steam,

- hot crude oil vapour,

- diluted alkali solutions (e.g. ammonium),

- diluted cold (normal temperature) mineral acids (e.g. nitric acid),

- cold organic acids (with the exception of formic, oxalic and acetic acid),

- diluted cold salt solution e.g. nitrates, nitrites, carbonates and other (with the exception of chlorides, sulphates and iodides),

- lubricants and mineral oils,

- petrol and other liquid fuels,

- alcohols and ethers,

- foodstuffs without table salt and other preservatives.

 

Example uses

Steam turbine blades, hydraulic press valves, cracking device machinery, pins, nuts, household items (cutlery).

This steel is a little but more difficult to weld than other 0H13 and 0H13J grades - appropriate conditions need to be ensured (preheating).

After welding to maintain intergranular corrosion resistance heat treatment is required - annealing or hardening and tempering.
