Stainless steel tanks are becoming popular for various storage applications. Whether it is food, cold storage, medical supplies, waste materials or outdoor storage, the purpose of tank is to regulate volume and pressure according to the type of application. In the context of stainless steel, the basic material used in the storage tank is known for its durability and strength. Moreover, the storage tanks manufactured with the help of stainless steel is in demand at present due to its high-performance and increased level of protection. But, if you are planning to buy the best stainless steel water tank and want to be assured about its reliability, then, following points need to be explored:

Stainless steel SS water storage tanks: Implication and versatile utility

Undoubtedly, the prevalence of stainless steel in the industrial applications is not new, but, the increased use for storage tank construction signifies paradigm shift in the market. From food & beverage industry to dairy, medicine and cosmetics, the storage tanks of highest grade have always been manufactured by the optimal use of stainless ...
... steel. Nevertheless, the selection of appropriate grade of stainless steel depends on the type of storage application. Let us consider the cases listed below to understand the factors influencing the use of specific stainless-steel grade:

• Stainless steel grade 304 or 316

It is crucial to prevent corrosion while handling water storage for drinking purpose. Therefore, the use of stainless-steel grade 304 or 316 is effective in handling cold or untreated drinking water. The impact of localized corrosion can make the water impure and also affect the longevity of the SS water storage tanks. Thus, the SS tanks are designed, fabricated and finished by using the appropriate grade of stainless steel for better utility.

• Residual stress control

Due to residual tensile stresses, SSC or stress corrosion cracking risk factors can be witnessed. Moreover, the high residual stresses or critical application need to be treated with the effective use of stainless steel 304 or 316 treatment. Also known as stress relief treatment, the process of controlling residual tensile stresses is accomplished with the optimal use of austenitic stainless steel. Nevertheless, if austenitic stainless steel does not seem to be the suitable solution to treat stainless steel water tanks, ferritic and duplex stainless-steel variants are the ideal alternatives to reduce the chances of SCC failure.

• Stress corrosion cracking risk factors

The imbalance of temperature, chlorides, oxygen level and tensile stresses can lead to stress corrosion cracking. With the help of water chemistry, chloride concentrates, stress concentrations and the other issues are treated while manufacturing the stainless -steel water storage tanks. Temperature issues are fixed with the help of advanced tank fabrication method while lessening engineering crevices. As a result, the risk of stress concentration will be reduced further preventing crevice corrosion attack.

Role of surgical stainless steel water tanks in medical environment

In order to cope with the requisites of biomedical applications and prevent mishaps in the medical environment, surgical stainless steel is preferred. Even though, there may not be a specific definition of surgical steel, it can be stated that surgical steel water tanks have high corrosion resistance level. To maintain safety while executing biomedical applications, austenitic 316 stainless steel, martensitic 440 and 420 grade variants of stainless steel are used to construction water storage tanks or other storage tanks for medical environment. Surgical steel is the very expensive as compared to the regular stainless-steel variety.
