Grain Size Requirements with 316L Forgings. When such forgings then are annealed, there may be abnormal grain growth in some areas. It is the small reductions of less than 10 15% that lead to this problem. An experienced forger will avoid light reductions in designing the progressions.

As a professional forging manufacturer, this article we would like to discuss how forging affects grain structure. Grain flow is one of the major benefits by the use of forgings. Unfortunately, there are misconceptions on the topic, which include the underlying causes of grain flow, the benefits that can be accrued from grain flow and how to

Mar 01, 2009 · A286 Forgings and Grain Size 2. The stock materials are either ASTM A638 Grade 660 or A891. After forging process, they are being solution treated and double aged. Then the mechanical properties are tested from specimens from the forgings and grian structure is also analyzed. The forging process and heat treatment are done by third party venders.

Forging is one of the oldest known metalworking processes. Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power to the production and working of iron in the 12th century allowed the use of large trip hammers or power hammers that increased the amount and size of iron that could be produced and forged. . The smithy or forge has evolved over

Hot Forging. While cold forging is very useful for increasing the strength of matals hot forging is widely used in manufacturing. The advantage is that the part can be formed without annealling and the grain structure will follow the form of the object being forged.

Measurement Methods. This approach measured grain size in terms of the number of grains visible on a cross section within a fixed area, the number per square inch at 100X, or the number per square millimetre at 1X, N A. From this value, the average cross sectional area

ASTM E112 Grain Size Examination. Using ASTM E112 as our accredited test specification, and an optical microscope, we can determine the average grain size in metallic materials such as plain carbon steels, alloy steels, stainless steels, cast irons, and titanium alloys.Grain size can be an important factor in the mechanical properties of materials, and typically a finer grain size can increase

Forgings offer broader size range of desired material grades. Forgings have grain oriented to shape for greater strength. Machined bar and plate may be more susceptible to fatigue and stress corrosion because machining cuts material grain pattern. In most cases, forging yields a grain structure oriented to the part shape, resulting in
