​

In addition, we provided shot peening service also. This specification applies to the processing of stainless steel components, intended for downhole service. The treatment creates a layer of compressive stress which prevents stress corrosion cracking, (SCC) as long as service stresses do not overcome the applied compression, and as long as wear and corrosion do not remove the compressed material. This specification should not be used when surface peening is used for surface conditioning (e.g. anti-galling) where there is no requirement for a compressive layer. 

 

Applications​

​

• Mag & Non Mag. Materials (Austenitic stainless steels such as 304, 316, 310, Nitronic 50)

• Precipitation Hardened Stainless steels such as 17-4PH, 15-5PH,  13-8 Mo

• Non-magnetic Drill collar steels such as P530, P550, NMS100, and DNM140.
