Description

A kind of lubricant for austenitic stainless steel drawing thin wire material

technical field

The invention belongs to the field of metal processing lubricants, in particular to a lubricant for austenitic stainless steel wire drawing materials.

Background technique

Austenitic stainless steel is the most important type of steel in stainless steel, and its output and usage account for about 70% of the output and total amount of stainless steel. Generally, austenitic stainless steel not only has high corrosion resistance, but also has good welding performance and cold deformability. At room temperature and low temperature, it has high plasticity and toughness, and does not have the characteristics of magnetism. These are valuable properties not found in ferritic and martensitic steels. According to the alloy method of the austenitic matrix, austenitic stainless steel can be divided into two series: chromium-nickel stainless steel and chromium-manganese stainless steel.

Chromium-nickel austenitic stainless steel has good corrosion resistance, good comprehensive mechanical properties and good weldability in various corrosive media, so it is widely used in chemical processing and food machinery. However, chrome-nickel austenitic stainless steel has high strength and low hardness, so it is not suitable for heavy loads and equipment or components that require hardness and corrosion resistance. The chromium-manganese austenitic stainless steel can be considerably strengthened due to the solid solution strengthening of nitrogen, and is suitable for many heavy-duty equipment components that do not require high corrosion resistance.

Contents of the invention
