The Solution for Descaling Steel Surfaces: Advantages of Premium Stainium Steel Abrasive

In the demanding and challenging field of metallurgy, especially in the production of steel or stainless steel, it is essential to achieve efficient, fast, and precise results when cleaning surfaces. Your technical solution may lie within our range of Stainium^TM steel abrasives, a premium W Abrasives product that includes special heat treatment, conditioning, and a unique blend of low-hardness round and angular shot.

What are the 3 main advantages of using Stainium^TM steel abrasive?

The Stainium^TM range of abrasives is specially developed to provide a precise solution for descaling stainless steel sheets before acid pickling. This usage is perfectly suited for specific environments in surface preparation within turbine shot blasting machines and represents a high-performance alternative in applications involving preparation of steel coils, springs, steel plates and sheets…

2 – Smooth and Better-Controlled Roughness

When using Stainium^TM abrasives, the results demonstrate lower roughness (Rz – lower average surface profile) and a more consistent surface finish (lower Rmax) on stainless steel. Stainium^TM outperforms other abrasives in terms of execution speed, surface finish quality, and cost reduction. Up to a 15% reduction in process costs is observed at our clients’ major sites, primarily due to a decrease in material consumption.

3 – Reduction in Consumption

Indeed, the efficiency of the combination of the two types of grains leads to a lower need for shot for consistently superior results, provided that the machine has correct settings.

• Your abrasive consumption is reduced on average by 12%.
• Your worn shot rejects are reduced by 15%.
• Possibility to reduce and/or eliminate your acid pickling process.

Choosing Stainium^TM means choosing cost reduction coupled with high production.

A Range of Stainium^TM Shot Tailored to Your Needs

The Stainium^TM shot range has several unique properties and blends designed to meet the constraints and performance needs of our clients.

SM150 and SM140: Low-hardness angular shot with specific heat treatment.

The calibration and specific angular shape of the grains provide better stabilization of the operational mix in the machine for optimum surface cleaning results.

Stainium^TM: A Premium Solution to Customer Challenges

Our technical and R&D teams place our clients’ challenges at the core of their quest for performance. Thus, a collaborative and trust-based effort is established to provide the right solution for the right application.

Improved Efficiency in Blasting Cleanliness

For one of our clients, major producers of raw steel, we recommended Stainium^TM 150 (instead of S110). After verifying the machines and the shot blasting process, there was a noticeable deviation from expectations. Upon using SM150, the results were immediate:

• Considerable improvement in cleanliness
• Enhanced roughness
• Optimized overall cost

Enhancement of the Shot Blasting Line

With several clients, Winoa experts gradually implemented the SM150 solution to replace the traditionally used low-carbon shot. The benefits were demonstrated in all cases:

• Reduced roughness
• Increased cleaning efficiency
• Improved shot blasting line productivity

Given the advantages of Low Carbon (LC) shot and its often advocated lower consumption by major clients, our teams are working to show that due to its efficiency, Stainium^TM offers lower consumption and a more cost-effective solution per square meter blasted.

Optimal Surface Profile

After several testing phases with a global steel group (shot blasting of steel and stainless steel plates), high carbon steel shot (HC) S110 was completely replaced by the Stainium^TM SM150 solution. This immediate effect was due to the characteristics of this Premium shot mix, providing high cleaning efficiency and an optimal surface profile, as well as the technical advice from WCare experts and their strong commitment to improving the entire process.

Spectacular results were achieved:

• Increased quality and stability of the roughness profile
• Reduced defects on the final product
• Lower consumption

Further trials are also underway on a second shot blasting line that uses low-carbon steel abrasive media. The teams are actively working to achieve similar improvements.
