Why won’t it rust?

Shiny and durable – that’s how stainless steel can be described. Its attractive appearance and unique properties help create the most complex yet eye-catching structures. However, precision machining of stainless steel is very difficult, requiring extensive knowledge, experience, and the right choice of tools.

Stainless steel, also known as noble or INOX (from the French inoxydable – “non-oxidizing”), is a group of corrosion-resistant steel. Its unique physical and chemical properties allow it to effectively resist, for example, atmospheric agents (gaseous corrosion), dilute acids, or alkaline solutions (corrosion in liquids). According to the accepted standard, stainless steel is an alloy of iron, carbon (maximum 1.2%), and chromium (not less than 10.5%). The latter element is mainly responsible for its corrosion resistance since it forms a thin but durable protective layer when reacting with the oxygen and water contained in the air.

Child of the revolution

Stainless steel was discovered in France in the second half of the 19th century during the height of the Industrial Revolution. Metallurgists discovered through experimentation that the iron-chromium alloy had unique properties – it was resistant to rusting and acidic substances. Several decades later, independently, a new type of steel was patented in 1912 in Germany and 1913 in the United Kingdom of Great Britain. It was English engineer Harry Brearley who was the first to use the term “stainless” – ang. “rustless steel” (later, the name “stainless steel” was adopted in the English-speaking world).

Types of stainless steel

The multitude of combinations in forming iron alloys with various elements (it happens that manganese, silicon, nickel, and molybdenum are added to the alloy) means that today there are about 70 types of stainless steel. The proportions of the elements added affect the characteristics of the alloy created. Four main types of stainless steel have been distinguished based on composition, microstructure, and physical properties. At Sabner, we have mastered the technique of manufacturing parts from each of them:

Ferritic steel (1.4000, 1.4003) contains relatively little chromium (10.5-18%), which may limit its corrosion resistance (this lack is compensated by its high resistance to chloride-induced intracrystalline stress corrosion). As a result, its use in water systems or outdoor structures exposed to the weather is limited.
Austenitic steel (1.4301, 1.4305; AISI 304, 303) – is the most common type of stainless steel. It contains 17-25% chromium and 8-25% nickel. It is characterized by very high flexibility and corrosion resistance, increasing with the amount of alloying additives like chromium and molybdenum (maximum 7%). It is not subjected to hardening during manufacturing and has enhanced elongation properties relative to ferritic steel. At Sabner, this type of steel is used to produce components for applications in the food or chemical industries, among others, as well as parts of sanitary fittings – hydraulic fittings, and valve elements. In addition, we manufacture parts of various types of austenitic steel for pneumatic systems and fasteners.
Austenitic-ferritic steel (1.4362, 1.4410) – the so-called duplex, or double steel, combines both characteristics. Thanks to a mixture of chromium (usually 20-26%), nickel (1-8%) and molybdenum (0.05-5%), it has good corrosion resistance in highly acidic environments. At Sabner, we use this type of steel to produce parts for tanks, water pipes, or gas pipelines.
Martensitic steel (1.4006, 1.4021; AISI 410, 412) – an austenitic steel subjected to quenching by cooling during manufacturing. This gives it a tough structure that is highly resistant to abrasion. Hardening means that the amount of chromium can be reduced (12-18%) without significantly affecting the quality of the product. At Sabner, we use this type of steel to produce medical parts and parts for pumps, shafts, and connecting elements.

Why stainless steel?

Corrosion resistance is not the only advantage of stainless steel. It has many other qualities, thanks to which parts manufactured from it are characterized by favorable parameters. The most important of these are:

Exceptional durability and strength – stainless steel parts can be used in aggressive environments and show high resistance to impact and deformation,
High resistance to extreme temperatures – makes it possible to install parts in equipment of any type, working in variable, often extreme conditions,
Ease of cleaning – since stainless steel has a smooth, non-porous surface that makes it difficult to deposit dirt and bacteria, parts made from it are easy to clean,
Shiny surface – stainless steel can be used to create visually attractive finishing and decorative elements,
Ecology – the manufacturing of stainless steel is primarily based on scrap metal. Moreover, parts made of this material are 100% recyclable.

Noble and demanding

Stainless steel can be daunting to machines. Due to its high strength, tendency to adhere, and low heat conductivity, cutting it on automatic lathes requires high competence. At Sabner, we have turning centers for the efficient machining of stainless steel. Proper training, knowledge, and experience allow us to effectively produce stainless steel parts in accordance with customer expectations.
