We coordinate grinding and polishing with partners. We machine the full grade range from austenitic (304, 316L, 321), through martensitic (420, 431), to duplex (1.4462) and super duplex (1.4410).
We work with stainless steels from leading manufacturers: Outokumpu Supra® and Forta® brands, Aperam Uginox® and Ugipure® brands, ThyssenKrupp Nirosta® brand and Sandvik Sanmac® brand (grades with improved machinability).
We machine 10 principal EN / AISI / W.-Nr. grades: 1.4301 (304), 1.4307 (304L), 1.4305 (303), 1.4404 (316L), 1.4541 (321), 1.4571 (316Ti), 1.4057 (431), 1.4021 (420), 1.4462 (Duplex 2205) and 1.4410 (Super Duplex 2507).
Key properties of stainless steels:
The natural passive layer formed by a chromium content of ≥10.5% is the basis of stainless steel corrosion resistance.
In the food industry, we machine tanks, mixers, fittings and conveyor components, mainly from 1.4301 (304) and 1.4404 (316L). For medical applications, we machine surgical instruments, housings and parts for non-invasive surgical equipment from 1.4021 (420) and 1.4057 (431). Hygiene and chemical resistance are key for both industries.
For the chemical industry, we machine pumps, flanges, valves and reactors from 316L and 316Ti. For marine applications, we select propeller shafts, fasteners and structural components, including duplex 1.4462 and super duplex 1.4410 for offshore.
In power generation, we machine turbines, heat exchangers and boiler components from high-temperature grades 1.4571 (316Ti) and duplex. For precision engineering, we make bushes, fasteners, housings and optical mounts.
We machine stainless steel into decorative and structural panels for architecture, automotive components and defence parts. The variety of grades – from austenitic and martensitic to duplex – allows the material to be selected for different mechanical and aesthetic requirements.

Stainless steels are iron alloys with chromium ≥10.5%, which provides a natural passive layer and excellent corrosion resistance. They are widely used in sectors requiring durability, hygiene, chemical resistance and machining precision. We specialise in CNC turning up to Ø415 mm and conventional turning up to Ø465 mm, 3-, 4- and 5-axis milling, and drilling of stainless steels. We coordinate surface finishing with partners for the automotive, food, chemical, medical, defence and power industries.

Inox is a commonly used term for stainless steel. It does not indicate a specific grade: there are more than one hundred stainless steels, each with its own physical and chemical properties, precisely defined by international standards. When ordering a component, state the EN or AISI designation, for example 1.4301, meaning AISI 304, 1.4305, meaning AISI 303, or 1.4404, meaning AISI 316L.
Yes, 304 steel can darken after heating, for example in the heat-affected zone during welding. The colour occurs when the oxide layer on the surface gradually thickens. The higher the chromium content, the later it appears. Colour cannot be assigned to one temperature because it also depends on heating time and surface condition.
At ANBI-TECH, we machine austenitic, ferritic, martensitic and duplex stainless steels. The grades most commonly machined include 1.4301 (AISI 304), 1.4307 (AISI 304L), 1.4305 (AISI 303), 1.4404 (AISI 316L), 1.4541 (AISI 321), 1.4571 (AISI 316Ti), 1.4057 (AISI 431), 1.4021 (AISI 420), 1.4462 (Duplex 2205) and 1.4410 (Super Duplex 2507). We also machine other grades specified in the customer’s technical documentation.
The corrosion resistance of stainless steels results from a chromium content of at least 10.5%, which forms a natural, self-repairing passive layer of chromium oxides on the surface in the presence of oxygen. Molybdenum in grades such as 1.4404 (316L) and 1.4571 (316Ti) improves resistance to chlorides, while titanium stabilisation in grades 1.4541 (321) and 1.4571 prevents intergranular corrosion at elevated temperatures.
EN 1.4305 (AISI 303) has the highest machinability and provides the easiest chip breaking because sulphur is deliberately added to its chemical composition. It is an optimum choice for production CNC turning and milling of fasteners, pins and bushes, although it has slightly lower corrosion resistance than 1.4301 (304). For applications requiring higher chemical resistance, austenitic grades 1.4301 and 1.4404 (316L) remain standard.

I can wholeheartedly recommend Anbi-Tech as a reliable and professional partner in machining and in manufacturing parts for the pharmaceutical industry. This is the third company where I have had the pleasure of working with Anbi-Tech, and the cooperation has been of the highest standard every time.
The pharmaceutical industry is exceptionally demanding: precision, on-time delivery, material quality and a full understanding of the customer’s needs all matter. Anbi-Tech has repeatedly proved that it is very well suited to this environment. The company has manufactured change parts, spare parts, filling needles, conveyor screws, components for dispensing powders and liquids, and many other production components for us.
The quality of the parts deserves particular recognition, whether they are made from 316L and 304 stainless steel or plastics such as POM, polyurethane and polycarbonate. The components are manufactured to a very high standard, with close attention to accuracy and detail, which is crucial in our industry.
Anbi-Tech has literally ‘saved our skin’ on many occasions in emergencies where time, a rapid response and a flexible approach to the customer mattered. A major strength of the company is its modern machinery, which enables it to complete even highly demanding projects while maintaining the highest standard of workmanship.
The people are equally important: the company’s staff always show complete commitment and a willingness to cooperate and provide technical support. Their extensive experience, professionalism and collaborative approach to customers are clear to see.
In pharmaceuticals, the ‘paperwork’, meaning certificates, is also important. The certificates have never been questioned during customer or regulatory audits, for example by GIF.
I strongly recommend working with Anbi-Tech to any company looking for a proven, reliable and quality-focused technical partner.
Dariusz Stachowicz, Senior Maintenance Manager, Polfa Warszawa S.A.
We had a very good experience working with Anbi-Tech on a new production line project for a bottling plant. Using a bottle sample and components from the old line, its engineer prepared the design and documentation for new change parts in SolidWorks. Anbi-Tech then manufactured timing screws, star wheels, drive components, bottle orienters, bottle turners and feeding components, among other items.
A major advantage is the end-to-end approach, from analysis and design through to the manufacture of finished components. Their considerable technical experience, precision and ability to solve unusual problems are clear. I recommend them.
Bartłomiej Ć, Specialist, ORLEN
We work with Anbi-Tech to manufacture parts and technical components for our projects. We value them above all for their workmanship, on-time delivery and excellent communication. When requirements are unusual, they can advise us and find a solution instead of simply manufacturing a part from a drawing. A reliable partner that I am happy to recommend.
Marek P., Production Manager, Triccor
A reliable company with extensive experience! They manufacture parts from steel, aluminium and specialist plastics such as POM and PTFE. Every service, whether turning, milling or CNC cutting, is carried out perfectly and with attention to the smallest detail. Excellent communication, professional advice and consistently on-time delivery. I wholeheartedly recommend them to anyone who needs reliable components.
