Therefore, the mechanical wear of its sealing surface is very small, and its sealing performance is very good. The disadvantage is that particles in the flowing medium may be trapped between the sealing surfaces. However, if the valve disc is made into steel balls or ceramic balls, this problem can be solved with toughness.<br \/>\nThe valve seat and disc of C4 steel globe valve are relatively easy to repair or replace, and there is no need to disassemble the entire valve from the pipeline when repairing or replacing the sealing element. This is very suitable for situations where the valve and pipeline are welded together.<br \/>\nC4 steel globe valve has the following advantages:<br \/>\nThere is no knife edge corrosion after welding, and it has good resistance to small hole corrosion and excellent resistance to stress corrosion;<br \/>\nC4 steel has good plasticity and toughness, which increases safety and reliability, and avoids the danger of industrial pure titanium igniting and exploding in nitric acid;<br \/>\nC4 steel has much better corrosion resistance than high-purity aluminum, and has mechanical properties that high silicon cast iron cannot match. Its welded joints have mechanical properties and corrosion resistance comparable to the base material.<br \/>\nThe use of C4 steel in pipelines, valves, condensers, pumps, and other equipment for the indirect method (magnesium nitrate method) of concentrated nitric acid is very effective.<br \/>\nThe material of C4 steel globe valve is 00Cr14Ni14Si4 ultra-low carbon austenitic stainless steel, which has excellent resistance to intergranular and stress corrosion cracking<\/p>\n<h1>FAQ: C4 Globe Valve<\/h1>\n<div><\/div>\n<div><strong>Alloy C4 (UNS N06455 \/ DIN 2.4610)<\/strong> is a nickel\u2011molybdenum\u2011chromium alloy, a refined version of Alloy C\u2011276 with lower carbon, silicon and iron content \u2014 offering exceptional stability and resistance to reducing and oxidizing media, widely used in the most severe chemical environments.
