Stainless Steel Materials

We offer a wide range of stainless steel material options to meet different CNC stainless steel machining needs. Stainless steel alloys are superior to conventional steel due to the addition of chromium. Different stainless steel alloys have unique properties to meet the specific needs of each industry for machining parts.

Stainless Steel 303:Stainless steel 303 is a great austenitic stainless steel. It is ideal for high-machinability parts. The material has an ultimate tensile strength of about 620 MPa, an elongation of 40%, and a hardness of about 85-95 HRB. The material has good machinability and corrosion resistance. Therefore, it is commonly used in the manufacture of parts for bolts, nuts and other precision components.

Stainless Steel 304/304L:Stainless steel 304/304L is by far the most commonly used type of stainless steel. 304 stainless steel material has an ultimate tensile strength of about 520 MPa, an elongation of about 50%, and a hardness of about 85 HB. 304L has a much lower carbon content, which results in better weldability. In addition, as they both have corrosion resistance and good molding ability. They are now widely used for piping as well as outdoor and other applications.

Stainless Steel 316/316L:Stainless steel 316/316L has excellent corrosion resistance and formability due to its molybdenum content. It has an ultimate tensile strength of about 580 MPa, an elongation of about 40%, and a hardness of about 70 HRB (316) / 65 HRB (316L). Due to its low carbon properties, 316 is more suitable for harsh usage environments. Examples include the marine and chemical industries.

Stainless Steel 17-4 PH:Stainless steel 17-4 PH is a high-strength precipitation-hardening material for aerospace and high-load applications. It has an ultimate tensile strength of up to 1,300 MPa, an elongation of about 5-10% and a hardness of about 36-44 HRC. this material is ideally suited for the manufacture of high-strength parts. This is due to its excellent mechanical properties as well as corrosion resistance for a variety of harsh environmental applications.

Stainless Steel 416:Stainless steel 416 is a martensitic stainless steel with good workability and high strength. It has an ultimate tensile strength of about 620 MPa, an elongation of about 20% and a hardness of about 45 HRC. this material is well suited for the manufacture of mechanical parts in low corrosive environments. Commonly used in the manufacture of cutting tools, valves and other parts requiring wear resistance.

Surface Finishes for stainless steel machined parts

Yonglihao Machinery can offer a range of finishing options for your stainless steel parts. Each finish option has its own different advantages, so please choose the one that suits your specific needs. Our CNC machining specialists are also happy to help you choose the right finish option if you have questions in this area.

As-Machined: This is the most cost-effective type of processing. This process physically removes material for precise shaping. It is usually used for machining parts where the surface requirements are not that demanding.

Sandblasting: Oxides and dirt are removed from the surface of the part by blasting abrasive particles at high speeds. This method provides an even, smooth and consistent matte appearance to the surface of the part.

Anodizing: Anodizing is the formation of a corrosion-resistant oxide film on the surface of a part through an electrolytic reaction. This process enhances the corrosion and wear resistance of the part while allowing the part to be dyed upon request.

Powder Coating: This process creates a strong coating on the surface of the part. It is often used to add color as well as texture to the part. It also enhances its corrosion resistance.

Polishing: As the name suggests, this process is used to make the surface of the part smooth and shiny by hand or chemical polishing.

CNC Machining Stainless Steel Applications

Due to the various special properties that stainless steel possesses, it is currently used in a wide range of industries. Some of the most common are medical, aerospace, and robotics. All of these industries rely on stainless steel for the production of high-strength parts.

Medical Industry: Stainless steel is widely used in the medical industry. This is due to stainless steel’s resistance to corrosion as well as its ease of cleaning and sterilization. It is often used to carry out the manufacturing of equipment such asscalpels and scissors, implants for medical treatment, and equipment housings.

Aerospace: Stainless steel is also common in the aerospace sector due to its high strength and high temperature resistance characteristics. It allows for the manufacture of complex parts that meet aerospace requirements while ensuring precision and strength. Specific parts that can be machined include engine components, structural assemblies, and connectors.

Robotics: Stainless steel can be CNC machined to enable the design as well as production of complex parts and high-precision components to meet the stringent performance requirements of robots. Commonly machined parts include robotic arms, sensor housings, connectors and brackets.
