Stainless Steel Valves
Corrosion Resistant Stainless Steel Valves
Petro-Valve has a vast stock of stainless steel gate, globe, check, ball, butterfly/wafer, and plug stainless steel valves made by a wide range of manufacturers such as Crane, Aloyco, Center Line, Xomox, Quadrant, Duo-Check, Flowseal, DSI, Durco, Worcester, PBV, Powell and Ladish.
Stainless steel does not stain, corrode, or rust as easily as ordinary steel, also called corrosion-resistant steel. There are different grades and surface finishes of stainless steel to suit the environment to which the material will be subjected. Stainless steel is used where the properties of steel, and resistance to corrosion are required. Stainless steel differs from carbon steel by the amount of chromium present. Carbon steel rusts when exposed to air and moisture. Stainless Steel contains sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion and blocks corrosion from spreading into the metal’s internal structure.
Stainless Steel Grades:
304 SSl - 304H & 304L - One of the most widely used and oldest of the stainless steels. This was originally called 18-8 which stood for its chromium and nickel content. It possesses an excellent combination of strength and corrosion resistance
310 SS - 310H - The strength of this alloy is a combination of good strength and corrosion resistance in temperatures up to 2100 F
316 SS - 316L - is an austenitic stainless steel has an increased molybdenum content to increase its resistance to corrosion when compared to other 300 series alloys.
317 SS - 317 is a high chromium, nickel and molybdenum version of 316 stainless designed principally for increased strength and corrosion resistance.
