Caluclating Forging Reductions Forging

Oct 26, 2006  A: Forging reduction is generally considered to be the amount of cross-sectional reduction taking place during drawing out of a bar or billet. The original cross-section divided by the final cross-section is the forging ratio (say 3:1). There is an equivalent reduction on upsetting for forgings being upset during forging (gear blanks, for example).

Forging Reduction Ratio - Upset Before Reducing Area ...

Jan 10, 2019  I know that forging reduction ratio is defined as the ratio of the original to the final cross-sectional area. However, I've recently encountered the suggestion that if an ingot is upset to increase the cross-sectional area before being forged to reduce the cross-sectional area, the reduction ratio is the ratio of the upset cross-sectional area to the final cross-sectional area.

EFFECT OF HOT FORGING REDUCTION RATIO AND HEAT

The present study was undertaken to investigate the effect of hot work reduction ratio in thermo- mechanical heat treatment (TMT) on the hardness and impact toughness of different grades of plain-carbon and low alloy steels. The effect of hot forging reduction ratios on the hardness and impact toughness properties are studied. An extensive study is carried out to investigate the combined ...

Calculating Reduction on Rings Forging

Mar 01, 2007  The grain size reduces upon annealing if the final forging temperatures are proper for the alloy. For example, overheating can occur at only 2,200°F for a low-alloy steel if there is little or no reduction. For austenitic stainless, final grain size is controlled almost entirely by the final forging reduction.

Nov 29, 2012  Die forging is a forging process that forging metal in plastic deformation under external force and be full of forging mold. Die forging can be divided into open die forging and closed die forging. Compared with the free forging, die forging must need a mold to forge. The mold of forging determines the size, shape and quality of products.

Forge Ratio - Metal and Metallurgy engineering - Eng-Tips

Oct 28, 2010  To put it more simply, forging ratio or work reduction ratio (for products other than forgings) is typically defined by the end user or design organization, and is based on intended service conditions of the end product. It really is an engineering process detail step that has been developed by experience from the end user.
