Stainless steels are generally more challenging to cnc machine than standard carbon steel and a general rule is that the higher a steel’s alloying content, the more difficult it is to machine. When machining stainless steels parts it is important to ensure that there is no dwell or rubbing caused by machine vibration or tool chatter. In all machining that involves cutting austenitic and duplex stainless steels, work hardening is more pronounced than in carbon steel or ferritic and martensitic stainless steels. The machined surface becomes harder at the same time as tool-life decreases.

Stainless steel is one of the most popular industrial alloys ever produced. These alloys demand carefully maintained tooling and machininur manufacturing professionals have a vast experience on different types of steel alloys, which allow them to adjust the Stainless steel is defined as a steel alloy with a minimum of 10.5 % chromium content by mass. As the name suggests, stainless steel is steel that should stain 'less' and not corrode. It should stain less, but it is not stain-proof. It is normally thought of as being corrosion-resistant, but given the wide range of grades of stainless steel, that is actually not a very useful defining characteristic, because it is the quality and grade of the stainless steel which determine its strength and corrosion resistance poor custom cnc machined parts

The base element in stainless steel is iron (Fe), and to this chromium (Cr) is added, which makes it into a corrosion-resistant alloy, an alloy being a mixture of metals. A small amount of carbon (C) is often included to increase hardness and strength. Nickel (Ni) may be added to stabilize the crystalline structure of the iron, and thus increase the integrity at all temperature extremes and to assist with corrosion-resistance. Other alloying elements such as molybdenum (Mo) or titanium (Ti) may be added to improve heat- and corrosion-resistance properties.roduction process to gain maximum efficiency and achieve high productivity.

Stainless Steel Types We Work With

We regularly work with the following types of stainless steel:

• Alloy 302: This is one of the most popular austenitic variety of stainless steel, which is well-known for its corrosion resistance, and ductility. The steel has a tendency to work harden, however, it can be easily overcome by slow speeds.  

• Alloy 303: This is the most easily machineable austenitic steel variety. This stainless steel grade exhibits excellent toughness. Sometimes sulfur addition may lower its corrosion and toughness. We always take care of the following while working with alloy 303 stainless steel types:

o Cutting edges are always sharp, because dull edges may cause work hardening. 

o Chip breakers are used to ensure that swarf remains clear of the work. 

o Huge quantities of coolants or lubricating agents are used to avoid heat concentration on the edges.

• Alloy 304: This stainless steel type comprises of 8% nickel, and 18% chromium, with the maximum carbon concentration of 0.07%. This austenitic stainless steel exhibits excellent corrosion resistance and offers excellent formability after CNC machining. Due to all these reasons, it is most commonly used for creating various commercial and home appliances. This steel is also easily weldable and can be easily welded using various resistance and fusion welding processes. 

• 17-4 PH Stainless Steel: This is a martensitic stainless steel, which is precipitation hardenable. These steels provide a comprehensive combination of mechanical properties such as corrosion resistance, oxidation, etc. The mechanical properties of this steel can be easily improved by heat treatment.  

• Alloy 400 Series: These stainless steels have 11 percent chromium, and 1 percent manganese composition. The steels are heat treated to harden.  These stainless steels have high carbon content, which contributes to its martensitic crystalline form. This structure provides high wear resistance and structural integrity after CNC machining. These steels aren’t’ excellent corrosion or rust inhibitors.
