What is Stainless Steel Alloy & What is it Used for
Usually, people call alloy steel with chromium content greater than 12% or nickel content greater than 8% stainless steel. This steel has certain corrosion resistance in the atmosphere or in corrosive media, and has higher strength at higher temperatures (>450°C). Steel with a chromium content of 16% to 18% is called acid-resistant steel or acid-resistant stainless steel, which is commonly referred to as stainless steel.
When the chromium content in steel reaches more than 12%, in contact with oxidizing medium, due to electrochemical action, a chromium-rich passivation film is quickly formed on the surface to protect the inside of the metal from corrosion; but in non-oxidative corrosion In the medium, it is still not easy to form a solid passivation film. In order to improve the corrosion resistance of steel, usually increase the proportion of chromium or add alloying elements that can promote passivation, such as Ni, Mo, Mn, Cu, Nb, Ti, W, Co, etc. These elements not only improve the corrosion resistance of steel Corrosion ability, while changing the internal structure and physical and mechanical properties of steel.
The content of these alloying elements in steel is different, which has different effects on the properties of stainless steel. Some are magnetic, some are non-magnetic, some can be heat treated, and some cannot. Due to the above characteristics of stainless steel, it is more and more widely used in industrial sectors such as aviation, aerospace, chemical industry, petroleum, construction and food and in daily life. The contained alloy elements have a great influence on the machinability, and some are even difficult to cnc machining and cutting.

The Material Type Of CNC Machining Stainless Steel Alloy
Stainless steel commonly used by BE-CU.COM is generally classified according to metallographic structure, and can be divided into the following five categories:
- Martensitic Stainless Steel: chromium content 12% to 18%, carbon content 0.1% to 0.5% (sometimes up to 1%), common ones are 1Cr13, 2Cr13, 3Cr13, 4Cr13, 1Cr17Ni2, 9Cr18, 9Cr18MoV, 30Cr13Mo, etc.
- Ferritic Stainless Steel: The chromium content is 12% to 30%, and the common ones are 0Cr13, 0Cr17Ti, 0Cr13Si4NbRE, 1Cr17, 1Cr17Ti, 1Cr17M02Ti, 1Cr25Ti, 1Cr28, etc.
- Austenitic Stainless Steel: 12%~25% complex, 7%~20% nickel (or more than 20%), the most typical representative is 1Cr18Ni9Ti, and the common ones are 00Cr18Ni10, 00Cr18Ni14Mo2Cu2, 0Cr18Ni12Mo2Ti, 0Cr18Ni18Mo2Cu2Ti, 0Cr23Ni28M03Cu3Ti, 1Cr14Mn14Ni, 2Cr13Mn9Ni4, 1Cr18Mn8Ni5N, etc.
- Austenitic + Ferritic Stainless Steel: Similar to austenitic stainless steel, it only contains a certain amount of ferrite in the structure. Common ones are 0Cr21Ni5Ti, 1Cr21Ni5Ti, 1Cr18Mn10Ni5M03N, 0Cr17Mn13Mo2N, 1Cr17Mn9Ni3M03Cu2N, Cr2bNi17M03CuSiN, 1Cr18Ni11Si4AlTi, etc.
- Precipitation Hardening Stainless Steel: contains high chromium, nickel and very low carbon, common ones are 0Cr17Ni4Cu4Nb, 0Cr17Ni7Al, 0Cr15Ni7M02Al, etc.
Top Stainless Steel Cnc Machining Case Studies
China Cnc Machining processes such as cnc milling, turning and swiss machining are today considered the most economic way to make stainless steel prototypes. Sometimes, however, certain non-machiningable materials are needed, and sometimes 3d printing is the only option. Our company has rich experience making stainless steel concept models and precise functional components. Understanding the properties of different stainless steel alloy, with lots of testing and experimentation with pre-heating, tool paths and other factors, we are able to minimize deformation on stainless steel alloy. Be-cu prototyping company provides a range of solutions for the machining of stainless steel parts.
