Sachiya Steel International is a recognized Manufacturer of ASTM A516 Gr 70 Plates , Sheets, Coils, which exhibits very good corrosion resistance in concentrated acid. Naturally aerated sulphuric acid in ASTM A516 Gr. 70 Carbon Steel Plates is more corrosive than de – aerated acid in the intermediate concentration range. Sulphuric acid in ASME SA 516 Gr. 70 Carbon Steel Coils is sometimes contaminated with chlorides which increases the corrosively of the solution.
However, ASTM A516 Gr. 70 Carbon Steel Slating Coils has good resistance, also in chloride contaminated sulphuric acid, especially at high concentrations. Heavily cold worked material such as ASME SA 516 Gr. 70 Carbon Steel Perforated Coils, however, can have tensile strengths as high as 220,000 psi (1517 MPa). Sachiya Steel International is one of the well-known dealer and supplier for high quality ASTM A516 Gr. 70 CS Plates, which has the innate ability to form a passive layer that prevents corrosion.

The 18 % minimum chromium content in ASME SA 516 Gr. 70 CS Coils provides corrosion and oxidation resistance, where it also must contain at least 10.5 percent chromium. ASTM A516 Gr. 70 CS Slatting Coils may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous and selenium. ASME SA 516 Gr. 70 CS Perforated Coils is an economical and practical choice for most environments, but it doesn’t have the chloride resistance.
