The 13CrMo4-5 is a heat-resistant alloy structural steel grade. The 13CrMo4-5 Flanges are designed with a superior chemical composition of carbon, silicon, manganese, phosphorous, sulfur, chromium, molybdenum, copper, and nitrogen. The superior content embedded in these flanges gives them good resistance to corrosive and oxidative media. The 13crmo4-5 Forging Alloy Steel Flange is produced at high temperatures using steel billets to shape strong flanges. These flanges have a tensile strength between 450 to 600 N/mm2 with a minimum yield strength of 300 N/mm2. A DIN 1.7335 Slip On Flange is a versatile grade that is slid on the pipe fixture and subsequently welded in place using one or more fillet welds. These flanges are generally preferred in low pressure and temperature applications. The 13CrMo4-5 Steel Weld Neck Flange is seen in high pressure and temperature applications. Designed with a long protruded hub, these flanges are welded in place using a butt-weld.

Why don't you directly contact a 13CrMo4-5 Steel Forged Flanges manufacturers in India? Supplier of 13crmo4-5 Forging Alloy Steel WNFF flange offers nondestructive (NDT) method

An Alloy Steel 13crmo4-5 Plate Flange is a flat, circular disc that is welded to the end of a pipe that can be bolted to another pipe. These flanges have a serrated finish and are usually fastened using a gasket between the bolts. The Alloy Steel 13crmo4-5 Spectacle Blind Flange is a high-strength grade that is designed with an open end and a spade. The spade is fitted in the line to curtail the flow during repair or maintenance. The open end is designed to allow the flow to travel in its normal conditions. A robust DIN 1.7335 Threaded Flange is threaded on the interior that aligns directly to different pipe fixtures. These flanges are reliable but are generally preferred in applications where the strain on the system is considerably lower. All these products are quality assured and can be supplied in a wide range of sizes and shapes.
