CNC Machining Stainless Steel Parts

CNC Machining Stainless Steel Parts

Since the invention of stainless steel at the beginning of this century, stainless steel has combined the image of modern materials and its excellent reputation in architectural applications, making its competitors envious. Stainless steel is also one of the strongest materials among the metal materials used in construction. Because stainless steel has good corrosion resistance, it can make structural components permanently maintain the integrity of the engineering design. The strength and high extensibility of the chromium-containing stainless steel machinery are combined, and it is easy to process and manufacture parts, which can meet the needs of architects and structural designers. In CNC machining, stainless steel occupies a large market. Due to its characteristics, it has always been welcomed by the machining industry. Precision CNC machining stainless steel components are usually used when components have to be durable, stable, and have an immaculate finish, for example, in medical engineering technology, mechanical equipment, automobile, industrial equipment, automation equipment, household appliances, toy, etc.

CNC Machining Materials for Stainless Steel Parts

CNC Machining Stainless Steel Engine Parts

Nitronic 60 is an outstanding general-purpose product with excellent wear and rust resistance. It has almost two times the yield toughness of SS 304 and also SS 316 and has superb oxidation resistance. Popular applications consist of bolts, valve stems, valve seats, pins, bushings, rings, bearings, as well as shafts.

Stainless steel is very resistant to rust and rust, making it suitable for use where parts might be revealed to the components for extensive durations. Stainless steel is additionally relatively ductile and ductile. JTR offers a variety of stainless steel alloys, consisting of food-safe ranges.

The 300 series (303, 304, and so on) are austenitic stainless steels (based upon their crystal framework) as well as are the most widely generated grades worldwide. Austenitic stainless steel grades are known for their high deterioration resistance as well as high stamina over a large temperature variety. With the exception of cool working, they are not heat treatable and also are typically non-magnetic.

400 collection stainless sheets of steel come from the martensitic family and also are not as usual as austenitic stainless steel. Martensitic steels are tough as well as very solid due to their greater carbon material however are more susceptible to rust in certain settings. They can be warm dealt with to significantly increase their firmness as well as are magnetic.

17-4 PH stainless steel is a high-strength, extremely corrosion-resistant product that preserves its toughness in temperatures approximately 1100 ° F. PH in its name stands for rainfall hardening, a therapy made use of to raise yield stamina. It is magnetic and also heats treatable with a hardness of approximately Rockwell C50.

About Stainless Steel Materials

Stainless-steel 303

SS301: Low content of Cr and Ni, the tensile strength and hardness are increased during cold working. non-magnetic, but it is magnetic after cold working.

304L  Stainless steel parts

Stainless steel 304L

The lower carbon content of 304L stainless steel helps reduce/eliminate carbide precipitation during welding. This allows 304L stainless steel to be “welded” even in severely corrosive environments. Using 304L eliminates the need to anneal welded joints before using the full metal form, saving time and effort.

Stainless steel 416

Alloy 416 is a martensitic, free-machining, chromium steel alloy generally considered the first free-machining stainless steel. It has the highest machinability of all stainless steel, approximately 85% of free-cutting carbon steel. Martensitic stainless steels are designed to be heat-hardenable and corrosion-resistant. Although Alloy 416 and other martensitic stainless steels are not as corrosion resistant as austenitic or ferritic stainless steels, they still exhibit good corrosion and oxidation resistance and high strength in the hardened and tempered condition. Alloy 416HT is easy to machine, always magnetic, and has low friction properties that reduce wear and seizing.

Stainless steel 440C parts

Stainless steel 440C

Grade 440C stainless steel is a high carbon martensitic stainless steel. High strength, moderate corrosion resistance, good hardness and wear resistance. Grade 440C achieves the highest strength, hardness and wear resistance of any stainless steel alloy after heat treatment. Its very high carbon content is responsible for these properties, making 440C particularly suitable for applications such as ball bearings and valve parts.
