Known for its shiny appearance and high strength, stainless steel is ideal for creating complex and aesthetic structures. Its attractive properties make it often chosen for demanding projects Precise machining. However, this process is complex and requires advanced knowledge, experience and the right tools to achieve the desired results.
Stainless steel, also known as stainless steel or INOX (from French “” — “non-oxidizing”), is a group of steel alloys characterized by corrosion resistance. Thanks to its physicochemical properties, stainless steel effectively protects against atmospheric effects (gas corrosion), dilute acids and alkaline solutions (corrosion in liquids). According to the standards, stainless steel is an alloy of iron, carbon (up to 1.2%) and chromium (min. 10.5%). Chromium plays a key role in providing corrosion resistance, as it reacts with oxygen and water in the atmosphere, it forms a thin but durable protective film on the steel surface.
Stainless steel was discovered in France in the second half of the 19th century, during the intense industrial revolution. Metallurgists of that era, through experiments, found that the alloy of iron with chromium was characterized by unique properties, such as resistance to rust and the action of acids. A few decades later, independently of each other, a new type of steel was patented—in Germany in 1912 and in Great Britain in 1913. It was English engineer Harry Brearley who first used the term “rustless steel”, which later evolved into “stainless steel” in English-speaking countries.
The variety of combinations in the creation of iron alloys with the addition of various elements, such as manganese, silicon, nickel and molybdenum, leads to the existence of about 70 types of stainless steel. The proportions of these additives affect the properties of the resulting alloy. Based on the composition, microstructure and physical characteristics, four main types of stainless steel are distinguished. In our company, CNCPartner, we have mastered the techniques of manufacturing parts from each of these types of steel
Containing relatively low levels of chromium (10.5-18%), this stainless steel may have limited corrosion resistance. However, it is characterized by high resistance to stress corrosion caused by chlorides, which partially compensates for this disadvantage. Therefore, its use in water installations and in structures exposed to weather conditions is limited.
It is the most commonly used type of stainless steel, containing 17% to 25% chromium and 8% to 25% nickel. It has excellent ductility and corrosion resistance, which increases with the addition of alloying elements such as chromium and molybdenum (up to 7%). Unlike ferritic steel, it is not subjected to hardening during production and has better elongation properties. At CNCPartner, we use this type of steel for the production of components for the food and chemical industry, as well as for sanitary fittings such as hydraulic fittings and valve components. In addition, from austenitic steel we manufacture parts for Pneumatic systems and a variety of fasteners.
Duplex steel, also known as double steel, combines the properties of ferritic and austenitic steel. Thanks to the combination of chromium (usually 20-26%), nickel (1-8%) and molybdenum (0.05-5%), it is characterized by high corrosion resistance in environments with high acidity. At CNCPartner we use duplex steel for the production of components for tanks, water and gas piping systems.
It is an austenitic steel, which during production is quenched by rapid cooling. This process ensures its high hardness and excellent abrasion resistance. Hardening allows to reduce the chromium content (12-18%) without significantly affecting the properties of the final product. At CNCPartner, we use this steel for production medical parts and components for pumps, shafts and connecting elements.
Corrosion resistance is just one of the many advantages of stainless steel. This material offers many other properties that affect the high quality of parts manufactured from this alloy. Here are the key features of stainless steel:
Parts made of stainless steel work well in aggressive environments and are characterized by high resistance to impact and deformation
They can be installed in a variety of devices that operate in variable, often extreme conditions.
With a smooth, non-porous surface that prevents dirt and bacteria from settling, these parts are easy to clean.
Stainless steel also allows the production of aesthetic finishing and decorative elements.
Moreover, the stainless steel production process is largely based on scrap recycling, and parts made of this material are fully recyclable.
Machining stainless steel can be challenging due to its high strength, tendency to adhere and poor thermal conductivity, which makes it difficult to cut on automatic lathes. At CNCPartner we have modern turning centers that allow efficient processing of this material. Thanks to the proper preparation, knowledge and experience, we successfully realize the production of stainless steel parts, meeting the expectations of our customers.
At CNCPartner, we have been specializing in the production of stainless steel components using Swiss lathes for a long time. Thanks to the advanced skills of our programmers and operators, we are able to carry out even the most complex projects for various industries.
