Citizen Cooling Solutions Limited is the leading Stainless Steel Grade 309/309S supplier in the Kenyan market and across the borders.
Alloy 309/309S austenitic stainless steel is typically used for elevated temperature applications. Its high chromium and nickel content provides comparable corrosion resistance, superior resistance to oxidation and the retention of a larger fraction of room temperature strength than a common austenitic Alloy 304.
309 is a highly alloyed austenitic stainless steel used for its excellent oxidation resistance. high temperature strength and creep resistance. The lower nickel content of SX309 improves resistance to Sulphur attack at high temperature. It is tough and ductile. and can be readily fabricated and machined.
