In the field of industrial manufacturing, there are strict requirements on the strength, corrosion resistance and processing performance of materials. Stainless steel bars have become the preferred material for the manufacture of many key components due to their excellent comprehensive performance. The following specific cases show the outstanding performance of stainless steel bars in actual projects.
Project Background
A well-known food machinery manufacturing company plans to produce a batch of new food processing equipment. The core components of the equipment need to be in contact with acidic and alkaline food raw materials and high-temperature steam environment for a long time, and the high precision and stability of the components must be guaranteed to meet the food production safety standards. After comparing and screening many materials, it was decided to use stainless steel bars as the production material for core components.
Stainless steel bar selection and performance advantages
Model selection
316L stainless steel bars are selected. This model belongs to low-carbon austenitic stainless steel. With the blessing of molybdenum elements, it has excellent corrosion resistance and high temperature resistance, which fully meets the hygiene and safety standards of food machinery manufacturing.
Core Features
Super corrosion resistance: 316L stainless steel rods have good tolerance to organic acids, inorganic acids and salt solutions. In the acid-base environment of food processing, they can effectively resist corrosion, avoid material loss and contamination of food raw materials, and their service life is 40% longer than that of ordinary stainless steel rods.
Sanitary and safe: It complies with international food contact material safety standards (such as FDA, LFGB, etc.), has a smooth surface and is not easy to breed bacteria, ensuring the safety and hygiene of the food processing process.
High strength and good processability: The yield strength reaches 170MPa and the tensile strength exceeds 480MPa, which can withstand the high load when the equipment is running; at the same time, it has good cutting, drilling and forming performance, which is easy to process into parts with complex shapes.
Processing applications and technical highlights
Precision processing: Use CNC lathes to perform high-precision turning and milling on stainless steel rods, and control the dimensional error within ±0.01mm to ensure the close fit of components and the stable operation of equipment. For example, when processing food stirring shafts, low noise and high-efficiency stirring can be achieved through precise size control.
Surface treatment: Polish the processed parts to make the surface roughness reach Ra0.8μm, which not only improves the aesthetics, but also further enhances the anti-fouling and corrosion resistance; some parts are passivated to form a dense oxide film to enhance the protective performance.
Welding process: For parts that need to be spliced, argon arc welding technology is used to ensure that the strength of the welding part is equivalent to that of the matrix, and the weld is smooth and flat to avoid residual impurities affecting the quality of food.
Project results and customer feedback
Performance compliance: After the equipment was put into use, after half a year of high-intensity operation, the core components did not have corrosion, deformation and other problems, effectively ensuring the stable operation of the food processing production line.
Customer recognition: The person in charge of the company said: "The parts made of 316L stainless steel bars have excellent corrosion resistance and precision, which greatly reduces the equipment maintenance cost and also improves the market competitiveness of our products."
Economic benefits: Due to the long life and low maintenance requirements of stainless steel bars, the cost of the equipment over its entire life cycle is reduced by about 30%, bringing significant economic benefits to the company.
This case fully proves that stainless steel bars, with their excellent performance and reliable quality, can meet the stringent requirements of the precision manufacturing industry and provide stable and efficient material solutions for various industrial projects.
