Stainless Steel Material – Customized High Quality CNC Machining Stainless Steel Parts Manufacturer

According to the definition in GB/T20878-2007, stainless steel is a steel whose main characteristics are stainless and corrosion resistance, with a chromium content of at least 10.5% and a carbon content of no more than 1.2%.

Stainless steel (Stainless Steel) is the abbreviation of stainless acid-resistant steel. The steel grades that are resistant to weak corrosive media such as air, steam, and water, or have stainless properties are called stainless steel; Corrosion) Corroded steel is called acid-resistant steel. Due to the difference in chemical composition of the two, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid-resistant steel is generally stainless.

Advantages Of CNC machining Stainless Steel

1. The number of fixtures is greatly reduced, and complex fixtures are not required to process parts with complex shapes. If you want to change the shape and size of stainless steel parts, you only need to modify the part processing program, which is suitable for new product development and modification.

2. The processing quality is stable, the processing accuracy is high, and the repetition accuracy is high, which is suitable for the processing requirements of aircraft.

3. The production efficiency is higher in the case of multi-variety and small-batch production, which can reduce the time for production preparation, machine tool adjustment and process inspection, and the cutting time is reduced due to the use of cutting volume.

4. It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts. The disadvantage of CNC stainless steel parts processing is that the machine tool equipment is expensive and requires a high level of maintenance personnel.

300 Series Stainless Steel

300 series stainless steel (common models are 301, 302, 302B, 303, 303L, 304, 304L, 304N, 305, 384, 308, 309, 309S, 310, 310S, 314, 330, 316, 316L, 316N, 316F, 317 , 321, 347, 348, etc.) is austenitic stainless steel, which is a non-magnetic alloy material containing iron, carbon, nickel and chromium, and has good forgeability. Known for their high corrosion resistance and high strength over a wide temperature range, austenitic stainless steels are the most widely produced grades in the world. They are not heat treatable except for cold working. Because 300 series stainless steel has many characteristics such as good appearance, it is widely used in heavy industry, light industry, daily necessities, architectural decoration and other industries.

400 Series Stainless Steel

400 series stainless steel includes martensitic stainless steel (common models are 410, 420, 440, 436L) and ferritic stainless steel (common models are 430, 409L), due to the high carbon content, martensitic steel is very strong and tough, but More susceptible to corrosion in certain environments. They can be heat treated to greatly increase hardness and are magnetic.

400 series stainless steel has a wide range of applications, such as exhaust pipes of automobile exhaust systems, mufflers, tailpipes, catalytic converters, washing machine inner barrels, tableware and other kitchen utensils, building materials, etc.

17-4 PH Stainless Steel

17-4 PH Stainless Steel is a martensitic precipitation hardening stainless steel which is a high strength, highly corrosion resistant material with durability to 1100°F. The PH in its name stands for precipitation hardening, a treatment that increases yield strength. It is magnetic and heat treatable to a hardness of approximately Rockwell C50. 17-4 is available in the annealed condition, H900 temper and H1150 temper. Generally used in offshore platforms, helidecks, food industry, pulp and paper industry, aerospace (turbine blades), mechanical parts, nuclear waste barrels.

Nitronic 60

Nitronic 60 is an excellent general purpose material with excellent wear and corrosion resistance. Nitronic 60 stainless steel provides corrosion and wear resistance at a very low cost compared to cobalt-containing and high-nickel alloys. Its overall corrosion resistance is superior to Type 304 in most media. It has almost double the yield strength of SS 304 and SS 316 and has excellent oxidation resistance. Often used in electric power, chemical, petrochemical, food and oil and gas industries, including expansion joint wear plates, wear-resistant pump rings, bushings, pins, bushings, bearings, shafts and rings, process valve stems, seals and logging equipment.

15-5 PH Stainless Steel

15-5 PH stainless steel is a high strength, high hardness, highly corrosion resistant material that retains its durability up to 1100°F, similar to 17-4 PH stainless steel. Compared with 17-4, 15-5 has better ductility and transverse toughness, and is easy to weld, has good processability and excellent mechanical properties. 15-5PH may be used to settle or heat treat conditions to obtain therapeutic properties. Applications: Aerospace, aircraft parts, component manufacturing high pressure valves and other corrosive environments, tanks, fasteners, equipment and equipment.

A286 Stainless Steel

A286 stainless steel is an iron-based superalloy, which has excellent corrosion resistance and maintains strength even at high temperatures. For applications requiring high strength and corrosion resistance up to 1300 °F (704 °C) and low stress applications at high temperatures Frequently used in engine components; the alloy is also used in low temperature applications requiring temperatures of at least -320 ° above chamber Ductile, non-magnetic high-strength materials are used in the temperature range of F (-196 °C). Alloy A286, although harder than other stainless steels, can be cold drawn and is an ideal metal alloy for cold rolling because it can be rapidly work hardened.

What Are The Surface Treatments Of CNC Stainless Steel ?

1. Mirror surface treatment, that is, polishing the outer layer of stainless steel, can be divided into two methods: physical and chemical. It can also be partially polished on the surface, which can make stainless steel more concise, high-end, fashionable and advanced.

2. Sandblasting mainly uses the power obtained by air compression to apply spray material to the outer layer to be treated at high speed, which can change the shape of the outer layer.

3. Chemical treatment is mainly to use chemistry and electricity together to form a stable compound on the outer layer of stainless steel. The most common type of electroplating is the type of chemical treatment.

4. Surface coloring is to change the color of stainless steel through coloring technology, making the color more diverse, and not only increasing the color, but also improving its wear resistance and corrosion resistance.

5. Surface brushing treatment, which is a very common decoration method in daily life, can form many patterns, such as threads, corrugations, and swirls. The treated surface is very smooth and delicate, and the wear resistance has also become stronger. It is widely used Used in electronics, electrical appliances, and mechanical equipment.

6. Spraying, it is essentially different from the above coloring treatment, because the required materials are different, spraying may cause damage to the oxide layer of stainless steel, but the stainless steel products with the most colors can be obtained in the simplest way , It can also change the feel of stainless steel.
