420 Stainless Steel Tube Supplier in China
Your Reliable 420 SS Pipe Manufacturer in China
420 stainless steel tubes, also known as surgical steel, are a type of martensitic stainless steel. These tubes can be hardened through heat treatment. We offer customized options for different sizes, shapes, and types of 420 stainless steel tubes to meet your specific requirements.
Features of 420 Stainless Steel Tube
420 stainless steel tubes have numerous superior advantages. They exhibit good strength, hardness, excellent ductility, and polishability. This stainless steel grade is known for its toughness compared to other stainless steel grades. Additionally, it offers corrosion resistance to atmospheric conditions, foods, fresh water, and mild acids. Our 420 stainless steel tubes also provide exceptional wear resistance in high-frequency usage applications.
Applications of 420 Stainless Steel Tube
420 stainless steel tubes are commonly used in dental and surgical instruments, including cutlery knife blades, lens molds, needle valves, straight edges, gauges, and various hand tools. Furthermore, they are utilized in pump shafts, plastic molds and dies, steel balls, scissors, gear shafts, cams, pivots, ball check valves, ball bearings, and shear blades. Our 420 stainless steel tubes can also be employed in bearings, bushings, fasteners, screens, mine ladder rungs, pump shafts, valve components, turbines, and steam and gas applications.

In summary:
– 420 stainless steel: Offers high hardness, wear resistance, and moderate corrosion resistance. Suitable for applications requiring hardness, such as knives and industrial components.
– 304 stainless steel: Provides excellent corrosion resistance, good formability, and versatility. Widely used in various industries including food processing, chemical processing, and medical equipment.
The decision on which option to choose relies on the particular needs and specifications of your intended use, with 420 stainless steel being more suitable for hardness and wear resistance, while 304 stainless steel excels in corrosion resistance and versatility.
In summary:
– 420 stainless steel: Offers high hardness, wear resistance, and moderate corrosion resistance. Suitable for applications requiring hardness, such as surgical instruments and industrial components.
– 316 stainless steel: Provides excellent corrosion resistance, particularly in corrosive environments and saltwater. It has good strength and toughness, making it ideal for marine, chemical processing, and food processing applications.
The decision on which option to choose relies on the particular needs and specifications of your intended use, with 420 stainless steel being more suitable for hardness and wear resistance, while 316 stainless steel excels in corrosion resistance, particularly in harsh environments.
In short, 420 stainless steel is not considered food grade. It is primarily used for applications requiring high hardness and wear resistance, such as knives. For direct contact with food, it is recommended to use stainless steel grades specifically designated as food grade, such as 304 or 316 stainless steel. These grades have better corrosion resistance and are commonly used in the food industry.
The hs code of 420 stainless steel is 72209090.
