  Different Base Materials of Forgings Lead to Varied Forging Requirements Stainless steel is a high-alloy steel with low carbon content (mass fraction of carbon generally ≤ 0.4%) and multiple alloying elements (mass fraction of alloying elements > 13%). Based on its matrix structure, stainless steel can be classified into  ferritic ,  austenitic , and  martensitic  stainless steels. Stainless steel is characterized by high deformation resistance, low thermal conductivity, sensitivity to overheating, and poor ductility. The forging requirements vary significantly depending on the base material of stainless steel forgings. 1. Forging Ferritic Stainless Steel Ferritic stainless steel forgings (e.g., 20Cr13, 10Cr17) contain low carbon (mass fraction ≤ 0.2%) and high chromium (mass fraction: 16%–30%). These steels undergo no structural transformation during heating or cooling, meaning heat treatment cannot refine grains or enhance strength. Only forging can refin...

  Formand Positional Tolerances of  Forged Products The "ideal shape" of a forging designed by engineerson technical drawings is the form intended to achieve the desiredfunctionality. However, due to manufacturing process influences, the"actual shape" of the forging inevitably deviates from the drawing. Causesof Form and Positional Errors in Stamped Parts The reasons for form and positional deviations in stamped parts are as follows: 1.       Dimensionalerrors  caused by tool adjustment, wear, cutting forces, or heattreatment. 2.       Formerrors  (e.g., roundness or flatness deviations) caused byclamping forces, cutting forces, vibrations, or residual forging stresses. 3.       Positionalerrors  (e.g., parallelism relative to an axis or surface) causedby cutting pressure, clamping forces, or machine tool positioning inaccuracies. In components such as crankshaft drive mechanisms, dimensionalaccuracy, roundness, and a...

  The 7 Processes of  Forged Steel Gear  Production With the advancement of modern technology,the quality requirements for gears have become increasingly stringent. As acritical foundational transmission component in the automotive industry, thequality of gears directly impacts vehicle noise, smoothness, and service life.To achieve the dual goals of high quality, low noise, and efficient production,what are the 7 key processes involved in gear manufacturing? 1. Forging the Blank Hot die forging remains the widely adoptedprocess for producing gear blanks in the automotive industry. In recentyears,  cross wedge rolling  has gained popularity for machiningshaft-type blanks. This technique is particularly suitable for complexstepped-shaft blanks, offering high precision, minimal post-forging machiningallowances, and high production efficiency. 2. Normalizing After forging, some manufacturers optfor  normalizing , while others use  annealing . Bothprocesses...
