Welded pipe is not weaker than seamless pipe. The steel is the same steel, the mill certificate says so, and a sound ERW weld will usually fail a tensile test somewhere other than the seam. What is true is that the design code does not extend it the same trust.…

The mill certificate can be perfect and the material still wrong for the job. That is what happens when tubing bought to ASTM A269 ends up in a duty that needed ASTM A213, because both arrived stamped 316L and both looked identical stacked on the rack. These three standards are…

Alloy 825 vs Inconel 825 Comparison is a popular discussion among engineers and buyers interested in corrosion-resistant nickel-based alloys for various harsh industrial applications. Even though the materials mentioned above may seem the same, knowledge of the alloy composition, UNS N08825 code, ASTM standards, mechanical characteristics, and uses is critical…

The chemical composition of Inconel is the only factor that can determine the performance of each grade in extreme service conditions. From corrosion resistance to weldability, a knowledge of just how much nickel, chromium, molybdenum and niobium exists within your selected Inconel grade is the key to determining all of…

Introduction When working with high-performance nickel alloys, understanding the distinction between an Inconel 600 plate and a sheet is essential for making the right procurement decision. The fundamental distinction is thickness: Plates are over 3.175 mm, while sheets are up to 3.175 mm. Whether you operate in chemical processing, aerospace,…

When engineering demands leave no room for failure — extreme heat, crushing pressure, and corrosive media all at once — Inconel 718 pipe is the material professionals specify. A precipitation-hardenable nickel-chromium superalloy, Inconel 718 (UNS N07718) delivers extraordinary strength from cryogenic temperatures all the way up to 700°C (1300°F), making…

Inconel is one of the most widely used superalloys in industries that require exceptional heat resistance, corrosion protection, and mechanical strength. From aerospace and marine engineering to chemical processing and power generation, this alloy performs reliably under extreme conditions where ordinary stainless steel or carbon steel materials fail. The term…

The most common question asked among the different industries in which is stronger, titanium or stainless steel pipe? The question is not so simple to answer, as it depends on what kind of strength you need in your application. Titanium is also characterized by its superior strength-weight ratio, being lightweight…

In the demanding world of industrial piping, selecting the right material is a balance of metallurgy and environment. Alloy 200 and Alloy 201 are two of the most desirable grades in extreme conditions at Stellar Alloys Steel Pipes and Tubes. Although the two are the same in terms of being…

In the demanding landscape industries, the selection of the right material determines the life of the structure for decades, and one that fails in months. But then the nickel-chromium-molybdenum alloys come in with their most used types, which are Hastelloy C276 and Hastelloy C22.   The two alloys are designed to…
