The company specializes in the production of carbon steel, austenitic stainless steel, duplex stainless steel, martensitic stainless steel, alloy steel forgings processing and forgings manufacturers. Our company has decades of production experience in the processing of finished forgings and forging processes. The products are inspected and controlled in strict accordance with the standards in terms of procurement, inspection, logistics and transportation, and customer service. The following are the problems that are more likely to occur during forging processing:

The forging process of forging processing means that the heating temperature of the metal billet is too high or the residence time of the high temperature heating zone is too long. Oxygen and other oxidizing gases in the furnace penetrate into the gap between the metal particles and oxidize with iron, sulfur and carbon to form a eutectic crystal of the fusible oxide, which destroys the relationship between the grains and reduces the material. Plasticity. Forgings are prone to problems. When the metal is excessively burned, the cracks are dealt with when the roughness is removed. When the metal is too long, lateral cracks appear in the burning place.

The copper is brittle and cracked on the surface of the forging. At high magnification, a yellow copper (or solid solution) is distributed along the grain boundaries. When the forging blank is heated, such as residual copper oxide in the furnace, the steel is reduced to free copper at a high temperature, and the molten steel atoms expand along the austenite grain boundary, which weakens the relationship between the grains. In addition, the high copper content [> 2% (mass fraction)] in steel, such as heating in an oxidizing atmosphere, forms a rich copper layer under the iron oxide scale, which also causes the steel to become brittle.

Forgings are prone to problems

There is no strict temperature boundary between combustion and overheating. In general, the grain is oxidized and melted into features to determine combustion. For carbon steel, when the grain boundary melts, severely oxidized steel (high-speed steel, Cr12 steel, etc.) is over-fired, and the grain boundary causes the fish bone-like body to melt. When the aluminum alloy is burned, grain boundary melting triangles and composite melting balls appear. After forgings are burned, they are often not preserved and must be scrapped.
