Different companies have different production standards (including machinery and equipment, parts, employee code of conduct, etc.), production habits and accumulated work experience. They should consider what products are suitable and what products are not suitable (or unlikely) based on this standard. Accuracy regulations and cost are based on various casting methods The accuracy of the obtained castings is different, the original project investment and production volume are inconsistent, and the economic benefits are also different. Therefore, to accomplish massive, faster, stronger and more economic development, everyone should consider all aspects.

Stainless steel castingIt is a general term for iron-based alloys used to produce castings that do not experience eutectic changes during the entire solidification process. A kind of casting alloy. Cast steel is divided into cast carbon steel, cast low alloy steel and cast special steel3kind.

Classification:

① Carbon steel casting. Stainless steel is cast steel with carbon as the primary alloying element and a small amount of other elements. Carbon content is lower than0.2%Is cast low carbon steel with carbon content0.2%——0.5%Is a cast medium carbon steel with a carbon content exceeding0.5%Is cast high-carbon steel. With the addition of carbon content, the compressive strength of cast carbon steel expands and the strength develops. Automatic coffee machine parts. Cast carbon steel has high compressive strength, plasticity and patience, and low cost. It is used in heavy machinery and equipment to make parts that accept heavy loads, such as steel rolling mill sound card racks, hydraulic press bases Etc.; used in rolling stock to make parts with high bearing capacity and impact resistance, such as bolsters, side frames, wheels and couplers.

②Stainless steel precision casting. Cast steel with alloying elements such as manganese, chromium and copper. The total output of alloying elements is generally lower than5%, It has great impact patience, and can get stronger physical properties after heat treatment. Casting low-alloy steel has better performance than carbon steel, which can reduce the quality of parts and increase the service life.

③ Casting special steel. Robot stainless steel parts are alloy cast steels that are habitually unique and must be refined, with a complete variety, generally with one or more high-volume alloy elements to obtain certain unique characteristics. For example, containing manganese11%——14%The high manganese steel is resistant to impact damage, and is mostly used for wear-resistant parts of mining machinery, robot stainless steel parts and construction machinery; various stainless steels with chromium or chromium-nickel as the first alloy elements are used in corrosion or650Parts working under high temperature standards above ℃, such as oil circuit boards, pumps, containers for chemical plants, or turbine generator covers for large-space power plants, etc. Precision casting specifications and models are high-precision, and the general linear dimension tolerance is1%, the view point size tolerance is ±1/2Degree, the surface smoothness reachesRa1.6-3.2, Which can save raw materials and production costs

Precision casting can project exquisite text orLOGOImages to enhance the quality of product images.

The raw materials of precision castings have universal functions, temperature resistance, wear resistance, corrosion resistance and the strength of the raw materialsHRC15-60, Can consider the requirements of various standards in work.

The total output of castings is flexible, from small to large batches, high efficiency, good repeatability; low-cost abrasive tools, low investment in product development projects.
