Ferritic stainless steel is difficult to abrasive blast and requires a highly experienced technician to ensure proper blast profile.If you dont have the proper blast profile,you will be 100% guaranteed to have an immediate and catastrophic failure.(For further reading,see Myth or Fact Higher Surface Profile Increases Coating Adhesion.)What is Strength of Steels - Definition Material PropertiesStrength of Steels.Steels consist of iron (Fe) alloyed with carbon (C).Adding a small amount of non-metallic carbon to iron trades its great ductility for the greater strength.Ultimate tensile strength of low-carbon steel is between 400 550 MPa.Weldability of Free Machining Grades of SteelFree machining types of steel contain higher levels of sulfur (0.05% or more),phosphorus (0.04% or more) or lead for improved machinability or machining characteristics.These types of steels would include AISI-SAE 11XX alloy series (resulfurized free machining) and AISI-SAE 12XX alloy series (resulfurized / rephosphorized free machining) (see figure 1).

Sulfur in the base metal combines with manganese to form manganese sulfide inclusions,which appear as stringers when the steel is rolled out.When metal at the high end of the AISI sulfur range (0.025 to 0.030 weight percent) is machined across the grain and then electropolished,those inclusions leave a large number of micron-size pits that provide initiation sites for pitting corrosion.Sour Gas Corrosion H2S Corrosion ResistanceNatural gas that have high sulfur and carbon dioxide contents (sour and acid gas) is reconized being extremely corrosive and dangerous.Special corrosion resistant material will have to be applied as Carbon steel is not suitable.Transportation from the wellhead to the sweetening plant must be done carefully.Selection guidelines for corrosion - Stainless Steel World13 Cr (Martensitic Stainless Steel) Figure 1 represents the generally acceptable regions of performance for 13 Cr stainless steel exposed to wet CO 2 containing NaCl.This figure is only applicable in the absence of oxygen and hydrogen sulphide (H 2S).Small amounts of oxygen can cause severe pitting of 13 Cr in the presence of chlorides.
