When Sand and Acid Start Eating Metal In many industrial plants, wear is not caused by abrasion alone. Corrosion is not caused by chemistry alone either. The real challenge begins when both occur at the same time: flowing media containing solids attack metallic surfaces mechanically, destroy the protective passive layer and allow aggressive chemistry to attack the exposed metal. This damage mechanism is known as erosion-corrosion. It is especially critical in components that

Introduction: Hygiene Is a Safety Factor In pharmaceutical and food processing technology, material selection is not only about corrosion resistance. It directly affects process safety, cleanability and product quality. Pipes, valves, vessels, pump housings, fittings and product-contact components must withstand aggressive cleaning media, steam sterilisation, purified water, CIP/SIP cycles and strict documentation requirements. Standard V4A stainless steel, such as 1.4404, is

Introduction: Industry 4.0 Starts with the Right Material Additive manufacturing is changing industrial production. Components are no longer only machined, forged, cast or welded — they can now be built layer by layer from metal powder or wire. This enables geometries that would be difficult, expensive or even impossible to produce using conventional methods: integrated cooling channels, bionic lightweight structures, complex brackets, patient-specific implants and high-perfo

Introduction: When One Delayed Delivery Puts the Entire Project at Risk In many industrial projects, material procurement is far more than a purchasing task. A missing round bar, an unavailable plate cut or a delayed special dimension can be enough to disrupt fabrication schedules, delay assembly and jeopardise commissioning deadlines. This risk becomes even more critical when working with nickel-based alloys, titanium, corrosion-resistant stainless steels or other special al

Introduction: A Raw Material Shortage Reaches the Shop Floor For many manufacturing companies, tungsten is an invisible but decisive cost factor. It is rarely listed directly in day-to-day purchasing orders, yet it has a direct impact on tooling costs, wear parts, high-speed steel, carbide tools and highly alloyed components. In 2026, the situation has intensified further: tungsten prices have reached record levels, driven by Chinese export controls and strongly rising demand

Introduction: When S355 Reaches Its Design Limits S355 has been a proven standard in steel construction and mechanical engineering for decades. It is widely available, offers good weldability and remains economical for many conventional load-bearing structures. However, modern machinery, lifting equipment, vehicle frames, crane structures, special-purpose constructions and mobile systems increasingly demand lower dead weight, higher payloads, improved energy efficiency and mo

When the Material Is Correct but the Certificate Is Missing, the Project Can Still Stop In technical projects, quality and approval do not depend on the material alone. It must also be possible to prove that the exact material delivered, processed and installed meets the specified requirements. This is especially important in safety-critical applications such as pressure vessel construction, plant engineering, mechanical engineering or components in contact with demanding med

When Stainless Steel Reaches Its Limits Stainless steel is widely regarded as the standard solution for corrosion-resistant applications. Materials such as 1.4301, 1.4404, 1.4571, 1.4462 or 1.4547 offer excellent performance in many industrial environments, from food processing and mechanical engineering to marine applications. However, in chemical process engineering, “stainless” does not always mean “sufficiently resistant”. Aggressive media such as hot sulphuric acid, hydr

Technical Introduction: Why Titanium Grade 5 Is the Standard for High-Performance Components When designs must be lightweight, high-strength, corrosion-resistant and reliable at the same time, Titanium Grade 5 / 3.7165 is often the material of choice. Internationally, this alloy is also known as Ti-6Al-4V and is one of the most important titanium materials for demanding technical applications. Unlike Titanium Grade 2, which is a commercially pure titanium grade, Grade 5 is sp

When V4A Is No Longer the Most Economical Solution V4A stainless steel such as 1.4404 is a proven standard in many industries: readily available, easy to weld, more corrosion-resistant than V2A and suitable for a wide range of industrial applications. However, in chloride-containing media, at elevated temperatures, in acidic process environments or where crevice corrosion is present, 1.4404 can quickly reach its technical limits. This is where super austenitic stainless steel

Selecting High-Performance Materials: Corrosion, Temperature — or Both? In chemical and energy engineering, material selection determines not only service life and operational safety, but also economic efficiency, testing requirements and procurement reliability. Two materials frequently specified for demanding applications follow very different technical strategies: 1.4462, also known as duplex stainless steel or 2205, is an austenitic-ferritic stainless steel designed for h
