Mainly used in the food industry and surgical equipment, adding molybdenum elements to obtain a special structure of corrosion resistance. Because of its better resistance to chloride corrosion than 304, it is also used as "marine steel. SS316 is usually used in nuclear fuel recovery devices. 18/10 grade stainless steel is usually also in line with this application level.

Source, definition and function of flange

2023-07-31

Flange is transliterated from English FLANGE, also known as flange or flange. A flange is an interconnected part of piping, valves, pumps, and other equipment to form a piping system. The flanges are sealed with gaskets, the flanges are provided with holes, and the two flanges are tightly connected by bolts. Before the invention of the flange, rivets were used to connect and fix the structure. With the addition of the flange, the construction and processing of crude oil were simpler.

How to improve the hardness of carbon steel hot pressing elbow

2023-07-31

The workpiece is reheated to 100-150 ℃ and kept for 5-20 hours. This kind of treatment for stabilizing the quality of precision parts is called aging. Aging treatment of steel components under low temperature or dynamic load conditions is particularly important to remove residual stress and stabilize the structure and size of hot-pressed elbows. Quenching and tempering treatment: The heat treatment method of high temperature tempering after quenching is called quenching and tempering treatment. High temperature tempering refers to tempering between 500 and 650°C.

Process Description of Austenitic Stainless Steel Forgings

2023-07-14

Austenitic stainless steel forgings are more difficult to forge than ordinary steel, but there are few surface defects. Most austenitic stainless steel forgings can be forged over a wide temperature range above 927°C. Since austenitic stainless steel forgings have no phase transformation in the high temperature range, the forging temperature is higher than that of martensitic stainless steel, but high chromium or low carbon stainless steel does not have the above properties, because when the temperature is higher than 1093 ℃, high chromium or low carbon stainless steel will produce different contents of ferrite according to the composition, which is harmful to forgeability.

What improvements should be made in the production process of forgings

2023-07-14

In the forging parts used today, if the temperature control is not good or the carelessness in the production process will cause a series of defects, which will greatly reduce the quality of the forging parts. In order to eliminate this defect in the forging parts, it is necessary to improve the metal parts first. In order to avoid the sensitive working pressure of the steel parts in the whole forging process, it can increase the relative density of the metal material, not only makes it less and less smooth and fine, and make it a high aluminum alloy, in the alloy steel carburizing, body shape broken.
