Stainless Steel


China stainless steel CNC has become one of the materials often selected by engineers due to its corrosion resistance and wear resistance. Stainless steel is one of the hardest metals in machining, so the cost is high, and it is difficult to ensure the quality of CNC China stainless steel turned parts and stainless steel milling parts. At LJZ CNC, we hold the key to a successful stainless steel machining supplier. Common types of stainless steel that we work with are austenitic, martensitic, 304, 303, 316, 420, duplex stainless steel, etc.


Stainless steel parts, as one of the important components of the machining industry, have also been developed. The use of tools on CNC machine tools for stainless steel machining parts has become a more extensive machining method in recent years. LJZ CNC is a professional stainless steel machining manufacturer. Inquiry about stainless steel laser cutting price!

Available LJZ China CNC Machining Stainless Steel

Stainless steel has high density, high hardness, and is non-magnetic. Therefore, it needs a different setup and tool selection when in machining. Supported by our professional engineers and advanced automated machining equipment, we have acquired confidence and experience in CNC China stainless steel machining technologies. High quality is the most reassuring guarantee.


Our precision CNC SS machining services are:


  • Stainless Steel Milling Parts (3, 4, 5 Axis CNC Milling)

Different kinds of CNC milling stainless steel due to the different mechanical properties and chemical composition of the difficulty of its stainless steel cnc milling is not the same. LJZ has  3 axis CNC milling, CNC milling 4 axis and 5 axis CNC milling.


  • China CNC Turning Stainless Steel

CNC turning stainless steel materials have the following characteristics: high adhesion and ductility, high work-hardening tendency, low thermal conductivity, high hardness, and high wear resistance. LJZ CNC can offer cnc turning stainless steel parts. During turning stainless steel on a lathe, if you have specific needs about mini size, we also offer turning stainless steel on a mini lathe.


  • CNC Swiss Screw Machining

LJZ is a professional CNC swiss screw machining company, Our swiss screw machining stainless steel strength and hardness is similar to medium carbon steel, but the plasticity is large, machining hardening is serious, so that the cutting resistance increases, consuming more power, coupled with the poor thermal conductivity of stainless steel, so that the temperature of the cutting area and the tool is high, the tool is easy to wear.


  • Tapping/Threading

  • Countersinking

  • Counterboring

  • Boring

  • EDM/WEDM


EDM stainless steel machining equipment can solve the problem of strengthening and alloy strengthening of different metal surfaces by transferring electrode materials such as cemented carbide to the EDM steel machining stainless surface firmly bonded by electric spark discharge at high temperature, making the metal surface hardened and wear-resistant, and corrosion-resistant. Inquiry LJZ EDM surface finish and metal rapid prototyping.


China Stainless Steel Machined Parts Surface Finishes

Surface Finishes on cnc stainless steel machining parts

We usually think that stainless steel will not be oxidized or corroded, so there is no need to do any surface treatment. That is wrong. Stainless steel will be oxidized and corroded in a certain environment and over a long period. In order to protect SS products, LJZ CNC offers the most professional surface finishes service, including:

  • Grinding,

  • Polishing,

  • Sandblasting,

  • Powder coating,

  • Electroplating,

  • Laser engraving, etc.


China Stainless Steel Machined Parts Materials

  • Alloy 302, 303, 304, 316, 316L

  • Alloy 430, 440

  • SS 17-4 PH


  • Machining 304 stainless steel

    As a low carbon 304 steel, in general, corrosion resistance is similar to 304, but after welding or stress relief, its resistance to grain boundary corrosion is excellent. In the absence of heat treatment, it can also maintain good corrosion resistance. 304 stainless steel has high corrosion resistance and good processing performance. It is widely used in the production of equipment and parts that require good overall performance (corrosion resistance and molding).


  • Machining 303 stainless steel

    By adding a small amount of sulfur and phosphorus to make it easier to cut and process than 304, other properties are similar to those and 304. 303 stainless steel is an alloy with excellent toughness, but this material isn't recommended for applications requiring welding. Commonly used for parts that need to be machined, ground or polished, including shafts, gears, valves, bolts, screws, etc.


  • Machining stainless steel 316

    316 stainless steel contains molybdenum and low carbon content, in marine and chemical industry environments, with pitting corrosion resistance. 316 stainless steel has better resistance to chloride corrosion than 304. Mainly used in food preparation machinery, laboratory equipment, surgical equipment, coastal paneling, marine parts, chemical containers, heat exchangers, fasteners, and springs etc.


  • Machining 410 stainless steel

    Martensitic (high-strength chromium steel), good wear resistance, corrosion resistance is poor.


  • Machining 440C stainless steel

    High strength cutting tool steel, with slightly higher carbon content, after appropriate heat treatment, can obtain high yield strength, hardness can reach 58HRC, which belongs to the hardest stainless steel among


  • 420 stainless steel

  •  Cutting grade martensitic steel, which contains at least 12% chromium for strong corrosion resistance. Also, it is used in surgical knives, which are very bright.
