Kencotube is leading manufacturer, stockiest & exporter of high quality ASTM A213 Gr T22 Alloy Steel Seamless Tubes, which has excellent resistance to a wide range of atmospheric environments and many corrosive media. ASTM A213 Gr T22 Alloy Steel Tubes is subject to pitting and crevice corrosion in warm chloride environments and to stress corrosion cracking above about 60 Degree C, where it is considered resistant to potable water with up to about 200 mg/L chlorides at ambient temperatures, reducing to about 150 mg/L at 60 Degree C. ASME SA213 Gr T22 Alloy Steel Seamless Tubes is widely used for a variety of household and industrial applications such as screws, machinery parts, car headers, and food-handling equipment. ASME SA 213 Gr T22 Alloy Steel Tubes is also used in the architectural field for exterior accents such as water and fire features.
ASTM A213 Alloy Steel Gr T22 Seamless Tubes contains both chromium (usually 18 percent) and nickel (usually 8 percent) metals as the main non-iron constituents. ASTM A213 Alloy Steel Gr T22 Tubes stains less easily than other iron-based metals, but it's not literally stainless. ASME SA 213 Alloy Steel Grade T22 Seamless Tubes is not very electrically or thermally conductive and is non-magnetic. ASME SA 213 Alloy Steel Grade T22 Tubes has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.
