Ścierniwa ze stali nierdzewnej wyróżniają się wyjątkową trwałością, odpornością na korozję i wysoką efektywnością pracy. Kluczowymi pierwiastkami w ich składzie są chrom i nikiel — to właśnie one w największym stopniu wpływają na parametry robocze i żywotność tych materiałów.

W poniższym opracowaniu wyjaśniamy, jak skład ścierniw nierdzewnych przekłada się na ich właściwości, jakie ich rodzaje stosuje się w przemyśle oraz w jakich procesach zapewniają one największe korzyści.

Stal nierdzewna wykorzystywana do produkcji ścierniw zawiera przede wszystkim chrom i nikiel.

• Chrom odpowiada za odporność na korozję — tworzy na powierzchni warstwę pasywną, która chroni ścierniwo i obrabiany materiał przed utlenianiem.
• Nikiel zwiększa udarność i wytrzymałość ścierniwa, co pozwala mu pracować pod dużymi obciążeniami bez ryzyka kruszenia.

Synergia tych pierwiastków sprawia, że ścierniwa nierdzewne są nie tylko trwałe, ale też minimalizują ryzyko zanieczyszczenia powierzchni żelazem. To kluczowe w branżach wymagających wyjątkowo czystej, odpornej na korozję powierzchni — m.in. spożywczej, medycznej czy przy obróbce aluminium.

Ścierniwa ze stali nierdzewnej są przeznaczone do obróbki materiałów, gdzie wymagana jest eliminacja ryzyka kontaminacji żelazem, takich jak: stal nierdzewna, aluminium, tytan, brąz i stopy kolorowe.

Ścierniwa ze stali nierdzewnej stosowane są tam, gdzie kluczowe jest uzyskanie czystej powierzchni bez ryzyka kontaminacji żelazem i zachowania odporności na korozję. W zależności od potrzeb technologicznych można wybrać śrut (kulisty) lub grys (ostrokrawędziowy) — każde z nich oferuje odmienne właściwości i efekty pracy.

Poniżej przedstawiamy główne różnice między tymi materiałami, ich zastosowania oraz wskazówki, jak dobrać właściwe ścierniwo do procesu.

In the field of shot blasting, there is an element that is often underestimated, but plays a key role in the entire process: the shot separation unit.

Let's find out why precise shot separation is the key to effective and efficient blasting process.

The slow-motion video provides an eye-opening picture of how each high-speed shot affects a contaminated surface. Kinetic energy is converted into cleaning power upon impact, making achieving a clean surface the result of millions of these small but powerful interactions.

When it comes to cleaning sand-covered surfaces, the type of grit you use can make a significant difference. Here are some types of shot that are very effective in these applications and that you will find in our product range:

Steel Shot: Known for its sharp edge shape, steel shot is perfect for aggressive cleaning,

Glass beads: ideal for soft surfaces, provide a smooth finish without changing the material.

Aluminum oxide: This type of shot is durable and reusable, making it cost-effective for large-scale operations.

The slow motion video clearly shows that a clean, sand-free surface is not achieved immediately. This is the cumulative effect of millions of high-velocity impacts, each contributing to the overall cleaning power.

In foundries, shot blasting is a key surface preparation and cleaning process. However, the presence of foundry sand can pose a significant challenge because it can contaminate the steel shot and reduce the effectiveness of the shot blasting process. In this article, we will discuss a specialized component of shot blast machines designed to solve this problem: magnetic cylinders.

Foundry sand is an essential element in molding processes, but during shot blasting it becomes a contaminant. When mixed with steel shot, it may cause premature wear of the machine and reduce the effectiveness of the cleaning process. In short, foundry sand is the worst enemy of a shot blasting machine in a foundry environment.

To counteract the harmful effects of foundry sand, some shot blast machines are equipped with magnetic cylinders. These cylinders are designed to attract and retain magnetic steel shot (shown in blue for visualization purposes) while allowing non-magnetic foundry sand (shown in red) to fall under the influence of gravity.

Magnetic cylinders are typically placed behind a traditional air separator, another item you may learn about in another article. When the mixture of steel shot and foundry sand passes through these magnetic

Abrasive blasting is one of the most versatile surface engineering processes. It uses the abrasive power of metallic abrasives, such as grit, spherical shot or stainless steel shot, to precisely shape and clean the surface of various materials. In this article, we will take a closer look at this fascinating process, its applications and the benefits it brings to various industries.

Abrasive blasting is used in many areas of surface engineering. It can be used to remove dirt, rust, paint and other coatings that deposit on metal surfaces. In addition, this process enables precise shaping and smoothing of the surface, which is particularly important in the production of components with high technical requirements.

Abrasive machining - basics

Abrasive machining is the process of removing material from a surface using abrasive particles. It can be carried out in various ways, such as grinding, polishing, milling or planing. Abrasive blasting is one of the abrasive processing techniques that uses the kinetic energy of metallic abrasives, including steel abrasives and stainless steel abrasives, to achieve the desired effect.

Shot blasting of steel - what is shot blasting of metal?

Metal surface treatment is often used to improve appearance, durability, corrosion protection or to prepare the surface for further processes such as painting, galvanizing or gluing. One of the methods of surface treatment of metals is shot blasting. What is worth knowing about this process? We explain!

What is metal shot blasting?

Metal shot blasting is the process of mechanically removing material from a metal surface using a stream of grains, called shot. Shot blasting can be done manually or with machines. This process is designed to improve the appearance and quality of the metal surface by removing contaminants, oxidation, rust, paint or other coatings, and smoothing out unevenness.

Steel shot blasting basics

When blasting steel, a stream of grains (usually made of metal, such as steel, stainless steel, aluminum, etc.) is directed towards the surface to be cleaned. The shot grains hit the surface at high speed, which removes impurities and gives a uniform appearance. This process can be controlled in terms of grain impact force, jet velocity and the type of shot used for shot blasting.

Abrasive blasting - what is it and how does it work?

Abrasive blasting is the process of mechanically removing material from a surface using a stream of abrasive grains such as sand, steel balls, glass beads or ceramics. It is a method used to clean, smooth, remove impurities, improve the appearance of the surface or change its properties. Examples of blasting methods include shot blasting and sandblasting.

During abrasive blasting, the abrasive is directed in the form of a strong stream onto the surface of the workpiece. This is done through special devices - such

Shot Blasting: Industry Shaping Technology

Shot blasting is an innovative method used in many industry sectors, from automotive to steel structures. This technology, despite its effectiveness and versatility, often remains incomprehensible to many. This article aims to understand this technology, discuss its history, process, applications, and also look at the future of shot blasting.

In the Footsteps of History: The Origins of Shot Blasting

The origins of shot blasting can be traced back to the beginning of the 20th century, when this technology began to gain popularity in the steel industry. Since then, shot blasting has come a long way, with groundbreaking discoveries and improvements that have made it an indispensable tool for many industry sectors.

In The Depths Of The Process: What Is Shot Blasting

Shot blasting, also known as sandblasting, is an industrial technique that involves "shooting" tiny particles of abrasive, known as "shot", into the surface of a material under high pressure. This process is commonly used to remove undesirable layers from surfaces such as rust, paint, grease, and welding residues, and to prepare surfaces before applying paint or anti-corrosion coatings.

Furthermore, shot blasting can also be used to increase surface adhesion by creating a fine, uneven texture that allows paints or coatings to adhere better. This makes the process extremely valuable in the construction, automotive, marine, aerospace and even sports equipment industries.

However, not all shot blasting processes are the same. There are many different techniques depending on the type of abrasive used. Here are some of them:
