Different enterprises have different production standards (including machinery and equipment, parts, employee behavior norms, 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. The precision regulations and cost fees vary depending on the casting accuracy obtained through various casting methods, resulting in inconsistent original project investment and production volume, as well as varying economic benefits. Therefore, in order to achieve large-scale, faster, stronger, and more economic development, everyone should consider all aspects. Stainless steel casting is a general term for iron-based alloys used in the production of castings that are not subjected to eutectic modification during the entire solidification process. A type of casting alloy. Cast steel is divided into three categories: cast carbon steel, cast low alloy steel, and cast special steel.

Classification:

① Carbon steel casting. Stainless steel casting is a cast steel that uses carbon as the primary alloying element and contains a small amount of other elements. Cast low carbon steel with a carbon content below 0.2%, cast medium carbon steel with a carbon content of 0.2-0.5%, and cast high carbon steel with a carbon content exceeding 0.5%. With the addition of carbon content, the compressive strength of cast carbon steel increases and its strength develops. Cast carbon steel parts for fully automatic coffee machines have high compressive strength, plasticity, and patience, with low cost. They are used in heavy-duty machinery to make parts that can withstand heavy loads, such as steel rolling machine sound card frames, water pressure machine bases, etc; Used on locomotives and vehicles to make parts that can withstand high force and impact, such as bolsters, side frames, wheels, and hooks.

② Stainless steel precision casting. Cast steel with alloying elements such as manganese, chromium, and copper. The total production of alloy elements is generally less than 5%, which has great impact patience and can undergo heat treatment to obtain stronger physical properties. Casting low alloy steel has better performance than carbon steel, which can reduce part quality and improve service life.

③ Cast special steel. Robot stainless steel parts are alloy cast steel that are habitually unique and must be refined, with a complete range of varieties, generally containing one or more diverse high alloy elements to obtain a certain unique characteristic. For example, high manganese steel containing 11% -14% manganese can resist impact damage and is commonly used in wear-resistant parts of mining machinery, robot stainless steel parts, and engineering machinery; Various types of stainless steel with chromium or chromium nickel as the primary alloying element, used for parts that work under corrosive or high temperature standards above 650 ℃, such as oil circuit boards, pumps, containers, or turbine generator casings for chemical plants. Precision castings have high precision specifications and models, with a general linear dimension tolerance of 1%, a viewpoint dimension tolerance of ± 1/2 degrees, and a surface smoothness of Ra1.6-3.2, which can save raw materials and production costs

Precision casting can project exquisite text or logo images on the surface of products to improve the quality of product images.

Precision casting raw materials have universal functions, including temperature resistance, wear resistance, corrosion resistance, and raw material strength reaching HRC15-60, which can consider the requirements of various standards in work.

The total output of castings is flexible, ranging from small to large quantities, with high efficiency and good repeatability; Low cost grinding tools and low project investment in the early stage of product development.
