Tension corrosion

Stress corrosion cracking (SCC) is the growth of crack formation in a corrosive environment. It can lead to unexpected and sudden failure of normally ductile metal alloys subjected to a tensile stress, especially at elevated temperature.SCC is highly chemically specific in that certain alloys are likely to undergo SCC only when exposed to a small number of chemical environments Corrosion of steel elements used in construction significantly alters their properties and impacts their overall strength. Several factors like environmental conditions and the material's inherent properties govern its toughness. The two major mechanical properties of construction steel that define their durability and capacity are compressive and tensile strength. Tensile strength. Tension force is one of the most common forces. As a result of this, many materials are specified by what is known as their tensile strength. The tensile strength helps users understand the amount of tension force a material will be able to withstand

Tensile stress (σ) is the resistance of an object to a force that could tear it apart. It is calculated with the highest tension endured by the object in question without tearing, and is measured in Newtons/mm 2, but was originally denoted in tons/inch 2.Tensile stress can be defined as the magnitude of force applied along an elastic rod, which is divided by the cross-sectional area of the. Post-Tensioned Concrete Corrosion & Repair. Eruption of PT Tendons caused by Corrosion Failure Early commercially available unbonded post-tensioning systems were susceptible to corrosion including paper wrapped, plastic push-through (stuffed) and heat-sealed (cigarette wrapped) sheathing systems due to their susceptibility to the ingress of water Eight Forms of Corrosion. by: Fontana & Greene, 1967. It has been shown that based on surface tension considerations the zinc content of a brass is higher at the grain boundaries. Depletion of chromium in the grain-boundary regions results in intergranular corrosion of stainless steels

Crevice corrosion: Similar to pitting, crevice corrosion occurs at a specific location. This type of corrosion is often associated with a stagnant micro-environment, like those found under gaskets and washers and clamps. Acidic conditions or a depletion of oxygen in a crevice can lead to crevice corrosion Corrosion handbook page 2 Corrosion handbook Foreword Corrosion is a ubiquitous natural process. Most of us, at some point in our everyday lives, become familiar with the effect that corrosion has on rusted steel parts. Corrosion has a huge economic impact. About a fifth of th

Post-Tech® PT Corrosion Evaluation - Non-Destructive Concrete Testing. Post-Tech® PT Corrosion Evaluation is a non-destructive test method that can assist engineers and building owners in the assessment of cable conditions.Post-tech PT Corrosion Evaluation is used to estimate the degree of moisture within the cable sheath which correlates to the risk of post-tension corrosion This page is based on the copyrighted Wikipedia article Stress_corrosion_cracking ; it is used under the Creative Commons Attribution-ShareAlike 3.0 Unported License.

This form of corrosion affects a wide range of metallic materials such as steel, titanium. The corrosion-proof tensioning component includes tensioning elements (3) such as steel rods or wires each encased in a plastic cover and with anchoring devices on the ends. A sealing disc (13) on the side facing away from the anchoring plate (6) of the anchoring device is locked against longitudinal displacement in relation to the tubular cover

  1. Torque'N'Tension 18 is a sealer with integrated torque-tension modifier for zinc and zinc alloy passivated films. It is designed to achieve a k-factor between 0.15 and 0.21 according to ISO 16047 using high hardness Steel bearing surface and Class 10 nut. Torque'N'Tension 18 also significantly improves the corrosion performance
  2. Greenkote® anti-corrosion protection. Tension Control Bolts Ltd has its own metal coating plant producing an environmentally friendly anti-corrosion coating called Greenkote, which is comparable to galvanising, although it is harder wearing and readily accepts all paint systems.
