The die forging rail presser generally selects a forging process.
Forged steel is a general term for iron-based alloys used to produce forgings that do not undergo eutectic transformation during solidification, and is one of forged alloys. The die forging track plate material is generally divided into three types: forged carbon steel, forged low alloy steel and cast special steel.
(1) Forged carbon steel. Cast steel with carbon as the main alloying element and containing a small amount of other elements. Forged low carbon steel containing less than 0.2% carbon, forged medium carbon steel containing 0.2% to 0.5% carbon, and forged high carbon steel containing more than 0.5% carbon. As the carbon content increases, the strength of the forged carbon steel increases and the hardness increases. Forged carbon steel has high strength, plasticity and toughness, low cost, and is used in heavy machinery to manufacture parts with heavy loads, such as rolling mill stands, hydraulic press bases, etc.; Parts that are subject to impact, such as bolors, side frames, wheels and couplers.
(2) Forging low alloy steel. Cast steel containing alloying elements such as manganese, chromium and copper. The total amount of alloying elements is generally less than 5%, which has a large impact toughness and can obtain better mechanical properties by heat treatment. Forged low alloy steel has better performance than carbon steel, which can reduce the quality of parts and improve the service life.
(3) Forging special steel. Alloy cast steels, tailored to meet specific needs, come in a wide variety and usually contain one or more high-alloy elements to achieve a particular property. For example, high manganese steel containing 11% to 14% manganese can withstand impact and wear, and is mostly used for wear parts of mining machinery and engineering machinery; various stainless steels with chromium or chromium nickel as main alloying elements, used in corrosion or 650 Parts that work at temperatures above °C, such as chemical valve bodies, pumps, vessels, or turbine casings for large-capacity power plants.
