These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures.

These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures. Thus, even third party inspection consolidates our claims about superior quality. A rejection rate of less than one percent has consolidated the claim.

Stress corrosion cracking occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides. High corrosion and erosion resistance is a must for storage tanks, whether the designer wants to prevent x789 during desalinization, avoid contamination in pharmaceutical or food processing, or store chips as well as black and white liquor for the pulp and paper industry.
