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.
