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
