Though, just like any other product, you must be very careful when importing stainless steel from foreign country or even domestically as it is a process that’s also anxious with danger. To help you avoid such drawbacks, here are some useful tips worth taking a look at when purchasing your stainless steel products. They contain some major things, but are not limited to the following;
First and leading, the stainless steel that you obtaining must be refined in two to three stages.
In India, most of the mills incline to use Stimulation Heaters to melt the scrap metal. Inappropriately, some of them are known to skip the second stage of purifying which is popularly known as AOD (Argon Oxygen Decarburization). This is an economical way of stainless steel manufacture with relatively minimal loss of precious elements. This is generally achieved through argon or nitrogen dilution which then minimizes examples of unwanted oxidation of precious metals such as chromium.
It is also possible that your present supplier doesn’t take his or her time to check and approve whether the scrap metal being melted is free from radiation or not. In India, radioactive contamination in Steel is well-defined as anything showing radiation level that’s above the natural background radiation level. In addition, it is also defined as anything that’s above the exempted total activity and activity concentration level of IAEA. The leading radioisotope of contamination is Co-60 that’s used industrially, Category 3 and below. Importers are commonly encouraged to obtain sensitive radiation monitoring instruments to support them monitor the incoming raw material. It is important to ensure that your supplier follows to and respects the above.
It is also worth revealing that some leading players have been known to buy semi or half finished -products from China then prepare what’s known in steel industry parlance as cold finishing or hot-rolling on the said products in India. They would then go fast and label the materials as “Originating from China. This false declaration is usually quite problematic to check and it is recommended that you maintain on having the origin of the material in question certified with a stamp and sign. This does prevent examples where the mill owner rejects the product if a problem crops up.
In conclusion, it is very essential to safeguard your investment by wisely choosing your suppliers so as to get the best deal. Make sure you involve your supplier as much as possible during the buying process so as to safeguard that you only get high quality stainless steel and nothing less.
