Sachiya Steel International is One Of The Leading Manufacturer And Exporter Of High Quality Carbon Steel Screws, where there is no single measure of corrosion resistance. The best steels to use for this purpose are the high nickel austenitic steels such as Carbon Steel Hex Head Screws, where in some cases, it can be considered. The resistance to pitting and crevice corrosion of ASME SA 307 Carbon Steel Socket Head Cap Screws increases with the content of chromium, molybdenum and nitrogen in the steel.

However, Carbon Steel Socket Set Screws is convenient to use the Pitting Resistance Equivalent Number (PREN) as a means of ranking the grades. Sachiya Steel International is one of the prominent supplier and dealer for high quality Carbon Steel Anchore Screws, which has high corrosion resistance in chloride containing media, including seawater.
Carbon Steel Blind Rivet Screws are more prone to precipitation of sigma phase, nitrides and carbides than corresponding austenitic steels, causing embrittlement and reduced corrosion resistance. Carbon Steel Concrete Screws is hyper – stainless steel for service in highly corrosive conditions was also very high mechanical strength is required. This makes Carbon Steel Threaded Screws ideal for use in deep – water umbilical and a range of other oil and gas applications. Carbon Steel Panel Screws is made in tune with different requirements of our copious clients.
