Low carbon grades are preferable because of better intergranular stress corrosion cracking (IGSCC) resistance. The candidate materials are 304L, 316L, and 347L. These materials are readily available and do not require preheat or postweld heat treatment.
Fig. 1. Corrosion specimen specifications. SSD aggregates, GP cement, flash calcined clay and limestone were dry-mixed about 5 min and then water was added and mixed for another 5 min. Eventually, fresh mixture filled the moulds by two layers and a vibrating table was employed for compacting each layer.

A 1mm thick deposit of limestone on the surface of heating coils may result in an energy loss of 10%. Corrosion and limestone deposits in plumbing systems lead to broken pipes, blockages and eventual flooding. Increased energy and water consumption as well as all other related costs are results of diminished performance of heating installations.
Corrosion, erosion, abrasion and scaling protection and remedy STEAM LINES Etching and scaling by borates and other salts Generally the chlorides carried by the endogenous steam do not exceed the maximum limit of 20 ppm (Appendix AS), and the carbon steel pipelines of com- mon thickness (6-7 ram) have a reasonably long life.
This rather catastrophic form of corrosion is when a rapid cyclic between carburization and the discharge of oxides on the metal surface takes place. This usually results in a greenish residue of chromium oxide and a …

If it gets wet, you will still need cathodic protection. So, just ensure that you don't shield the CP. I think it is generally considered that crushed limestone backfill, that has a tendency to result in high pH for some time in an aqueous environment, is generally considered a material non-corrosive to steel.
Acidic water is a nuisance and causes corrosion in the pipes, especially those made of copper. Water treatment with the help of limestone is a common practice as they help in maintaining the acid balance of the water and aid in the removal of iron and its by-products.

Erosion corrosion is defined as the accelerated deterioration of a metal that results from the relative movement between a corrosive liquid and a metal's surface. As the fluid flows along the surface (usually at high velocities), the metal's passive oxide layer may be removed or dissolved, leaving the alloy susceptible to damage.
