Stainless Steel Sheet Bending
Stainless steel plate bending is a process in which external force is applied to cause permanent plastic deformation of metal plates beyond their elastic limit.
Types of Stainless Steel Deep Processing:
Milling
Milling is the most common primary stainless steel machining process. It uses high-speed rotating cutting tools for a stationary workpiece. Choosing the right tool when using milling machines on stainless steel alloys is important. Wrong tools or high speeds can result in rapid tool wear. Milling stain steel has a very high accuracy and a smooth cutting edge.
Turning
Turning requires a stationary cutting tool and a rotating workpiece. The tool comes in physical contact with the rotating workpiece to remove material. Turning is a common process for machining austenitic stainless steel. It is important to keep tool overhang minimum when machining stainless steels.
Drilling
Drilling is a secondary machining process used in conjunction with other metalworking techniques. Drilling is done to create holes in the metal workpiece. Stainless steels are drilled for screw holes, secondary assembly, or aesthetics.
Threading
Threading is done on steel parts for mounting screws and fasteners. The threads can be inside a hole or the exterior of the workpiece. Threading on stainless steel are usually carried on pipes and tubes.
Laser cutting
Laser cutting uses an amplified light beam for melting and removing stainless steel. This method only works for thin sheets of stainless steel. It is better than cemented carbide tools because tool wear doesn’t occur. However, it is very expensive and requires highly skilled labor.
Grinding
Grinding is done to enhance the surface finish of the stainless steel. It can also make the workpiece more accurate by removing material in very low volume. Grinding rubs abrasive wheels against stainless steel workpieces. This process can also remove the burrs created due to welding. Grinding can help in creating a smooth cutting edge on stainless steel parts.
EDM (electrical discharge machining)
Electrical Discharge Machining (EDM) uses electrical pulses to melt the metal. The electrical pulses have a very high voltage and frequency. This process is limited in terms of stainless steel cutting thickness.
Waterjet cutting
Waterjet cutting uses the force of high-pressure water for material erosion and cutting. This process can cut thick sheets of stainless steel. However, if the particular stainless steel grade has low corrosion resistance, waterjet cutting can cause adverse effects.
Industrial and construction
Stainless steel is commonly used in industrial and construction applications due to its high strength, durability, and corrosion resistance. It is used for structural components, fasteners, and reinforcement bars in concrete.
Food and beverage
Stainless steel is a hygienic material that is widely used in the food and beverage industry. It is used for processing equipment, storage tanks, and kitchen appliances due to its corrosion resistance and easy-to-clean surface.
Medical and pharmaceutical
Stainless steel is a biocompatible material that is commonly used in medical and pharmaceutical applications, such as surgical instruments, implants, and medical equipment. It is resistant to corrosion and can be sterilized easily.
Automotive and transportation
Stainless steel is used in automotive and transportation applications due to its high strength-to-weight ratio and corrosion resistance. It is used for exhaust systems, suspension components, and fuel tanks.
Aerospace and defence
Stainless steel is a critical material in aerospace and defence applications due to its high strength, corrosion resistance, and heat resistance. It is used for aircraft components, rocket engines, and missile casings.
