Stainless steel is a universal workpiece material, and its widely used strength and heat resistance and corrosion resistance are essential. However, the characteristics that make stainless steel alloys into special structural materials also complicate the process of making them into functional machining parts. Careful consideration of the combination or balance between tool performance and geometry, as well as the application of aggressive cutting parameters, can significantly increase the productivity of stainless steel machining operations. In this article we mainly discuss about the properties and advatanges of stainless stell machining parts.
The following knowledge points are listed below:
Yield Strength of stainless steel machining parts
High temperature strength of stainless steel machining parts
tensile strength of stainless steel machining parts
Low temperature resistance of stainless steel machining parts
Ductility of stainless steel machining parts
Higher work hardening rate of stainless steel machining parts
Conductivity and magnetism of stainless steel machining parts

Other attributes of stainless steel machining parts
According to different grades, stainless steel can exhibit the characteristics of high strength and low elongation or low strength and high elongation. In terms of yield strength, they compare well with carbon steel.
The performance of stainless steel at higher temperatures is better than other carbon steels. Due to its high strength retention coefficient at high temperatures (above 500°C), it has better fire resistance. Compared with carbon steel above 300℃, it also has a better stiffness retention coefficient.
When it comes to tensile strength, stainless steel is superior to aluminum, brass and mild steel.
The highest tensile strength occurs in the precipitation hardening and martensitic grades. The tensile strength of these grades is twice that of the ubiquitous 304 and 316 grades. Especially dual-phase steels have a high strength/ductility ratio.
Some grades of stainless steel are very good at handling a wider range of temperatures. Austenitic steel shows special toughness and increased tensile strength at sub-zero temperatures. This greatly broadens their scope of use and opens up new avenues for modern applications.
On the other hand, ferrite, martensite, and precipitation hardening grades are not as good at low temperatures because their toughness decreases as the temperature decreases.
The ductility of different grades of stainless steel is very different. Some grades have high ductility, allowing the use of arduous drawing processes.
This property refers to the ability of a metal to increase its strength through a cold working process. Stainless steel can be annealed and cold worked to adjust its strength to the required level.
This means that by changing its strength, the same grade can be used for multiple applications. For example, through annealing and cold working, the same grade can be used for springs or bendable wires.
Like all metals, stainless steel also conducts electricity. However, this conductivity is very low in all steels.
In industries with high hygienic standards or in environments where electrical appliances may be corroded or humid, the stainless steel housing is used for protection.
Austenitic stainless steel is non-magnetic, but in some grades, cold working can be used to improve its magnetic properties. All other types show magnetism.
The chemical properties make this material unique and unique.
This distinction of stainless steel is the reason for its many unique applications in industry. The high oxidation resistance is due to the chromium in stainless steel. In some grades, the chromium content can be as high as 26%.
Other metals can be protected with coatings and anti-corrosion coatings, but as soon as it wears, corrosion begins. For stainless steel, after the natural coating of chromium oxide caused by surface damage is removed, a new coating is formed on the exposed surface to prevent corrosion deterioration.
Important properties are not limited to machinery and chemistry. There are also some useful tools for various applications in the list below.
(1) Recycling capacity
As mentioned earlier, it is possible to recycle stainless steel to make new products. This reduces the environmental pressure on our steel demand by reducing the demand for raw materials and reducing waste formation.
Its non-biodegradable nature also prevents it from polluting resources because it will not decompose and seep into soil or reservoirs.
(2) Easy to work together
Stainless steel is highly machinable and maneuverable, allowing designers to create complex shapes and products. Stainless steel laser cutting.
