Welding till the End!
Iron and carbon are the most abundant materials present in steel. Pure iron is not particularly strong or hard on its own, so it is the addition of carbon/other alloying elements that gives steel its increased strength. We will discuss carbon steel types in this article. Carbon steel is a steel with carbon content from […]
Stainless steel also known as inox, corrosion-resistant steel(CRES), and rustless steel, is an alloy of iron which is resistant to corrosion and rust. It contains iron with chromium, nickel and other elements like molybdenum, carbon, manganese and nitrogen depending on specific grade. Stainless steel’s corrosion resistant property results from presence of chromium 10.5 % or
Welding Hazards and Safety Measures: Ensuring a Safe Working Environment Welding is a very important skill that affects nearly all aspects of our lives-from the cars we ride to the buildings we live in. However, welding also imposes common hazards, to prevent ourself from this hazard, safety is a must. Most of the common hazards
Pitting resistance is a critical factor in selecting materials for piping systems, particularly in industries where corrosion can pose significant challenges. One of the essential metrics used to evaluate this resistance is the Pitting Resistance Equivalent Number (PREN). This article delves into the complexities of pitting corrosion, how PREN number are determined, and what they
A Vernier scale is a precise measuring instrument used in various scientific and engineering fields. It enhances the accuracy of measurements by allowing the user to read values between the smallest graduations on the main scale. Understanding how to read a Vernier scale is essential for anyone working with precise measurements, whether in mechanical engineering,
Welding is a critical process in numerous industries, from construction to automotive manufacturing. One of the key factors in achieving a successful weld is understanding the concept of polarity. In welding, polarity refers to the direction of current flow, which can significantly impact the quality and characteristics of the weld. This article will explore the
Ferrite testing, also known as a ferritescope test, is a fast and non-destructive inspection technique used to measure delta ferrite levels in austenitic stainless steel and duplex stainless steel materials. Maintaining the correct ferrite content is crucial for ensuring corrosion resistance, durability, and preventing cracks in the material. Exceeding the maximum allowable ferrite content can
There are several methods available for joining metals, including welding, brazing and soldering. What is the difference between welding and brazing? What is the difference between brazing and soldering? Let’s explore the distinctions plus comparative advantages as well as common applications. This discussion will deepen your understanding of metal joining and help you identify the
Hardness refers to the resistance of a material to deformation, particularly when subjected to various forms of external forces like compression, indentation, scratching, or abrasion. It’s an essential mechanical property that indicates the material’s ability to withstand such forces without undergoing permanent deformation or damage. Hardness is influenced by factors such as the material’s composition,
Magnetic Particle Inspection (MPI) stands as a crucial nondestructive testing process utilized to detect surface and shallow subsurface discontinuities in ferromagnetic materials. These materials encompass iron, nickel, cobalt, and certain alloys susceptible to magnetization. The method involves establishing a magnetic field within the test object, achieved through direct or indirect magnetization. Direct magnetization passes electric
