C-Mn and low alloy steels undergo a sharp change in their resistance to brittle fracture as their temperature is lowered so that a steel that may have very good toughness at ambient temperature may show extreme brittleness at sub-zero temperatures, as illustrated in following figure. -- -- -- Ductile.

EPRI-supported research has identified critical material information regarding the factors affecting the performance of creep strength-enhanced ferritic steels, in general, and Grade 91 steel, in particular. EPRI recommendations emphasize that a five-point, integrated strategy should be used for the effective life management of components fabricated from tempered martensitic by: 2.

Welding is a vital process required in the fabrication of ‘fracture critical’ components which operate under creep conditions. However, often the procedures used are based on ‘least initial cost’. Thus, it is not surprising that in many high energy applications, welds are the Author: Jonathan Parker, John Siefert.
This paper describes characteristics of transgranular cleavage fracture in structural steel, viewed at different size-scales. Initially, consideration is given to structures and the service duty to which they are exposed at the macroscale, highlighting failure by plastic collapse and failure by brittle is followed by sections describing the use of fracture mechanics and materials Cited by: 4.
naphthenic acid corrosion but a minimum of about to % is indicated to be necessary. There are some works published in the literature that agree with this statement and also specify that the addition of Mo in the alloy considerably increases its resistance to naphthenic acid corrosion The use of austenitic stainless steels in distillation.
Low-alloy steels (LASs) are extensively used in oil and gas (O&G) production because of their good mechanical properties and low cost. Use of these materials in environments containing H 2 S is governed by the ISO standard (NACE-ISO, ), “Petroleum and natural gas industries – materials for use in H 2 S-containing environments in oil and gas production”.Cited by: 5.
Steels having a carbon content less than % C are called hypoeutectoid steels and those with more than % C are called hypereutectoid steels. (A simple reminder to keep track of these two terms is to remember that hyper rhymes with the word higher and thus hypereutectoid steel has the higher carbon content, i.e.

In most cases, stainless steels are selected for their corrosion- or heat-resisting properties. By nature of the passive, Cr-rich oxide that forms, these steels are virtually immune to the general corrosion that plagues C-Mn and low-alloy G c t u r a l steels.4/5(5).
The results of other austenitic steels with various quantities of C, Mn, Cr, and Ni are also indicated in this figure. The plot of the %C steel deviates considerably from the linear relationship of the austenitic steels (hatched band) due to the hard phase (martensite) by: 1.

49–Cited by: The alloying elements in stainless steel contributing most to corrosion resistance are chromium and molybdenum.
Within each of the alternative groups there are grades with different corrosion resistance resulting from the chromium and molybdenum contents. The well known austenitic series grades contain the highest levels of nickel.
An updated, revised and expanded version of Professor Burdekin's earlier work of the same title, this book explains this branch of thermal engineering in clear, practical terms. It concentrates on steels - the most predominant engineering media - and is essential reading for all those involved in the study or practice of welding high.

Multiple leaks were observed in scattered locations of a piping network of around 10 km after only 4 months in service transferring ammonium sulfate solution. The initial investigation indicated that the piping network was constructed 3 years earlier.
After the construction Author: Mohammed Al Muaisub. Introduction. Microalloyed (MA) steels, also known as high-strength low-alloy (HSLA) steels, have become an indispensable class for a range of applications such as in the construction of large ships, oil and gas transmission lines, offshore oil drilling platforms, pressure vessels, building construction, bridges, storage tanks and by: Enhanced cooling via forced convection using cryogenic liquid is an option for controlling grain growth in the heat affected zone (HAZ) of ferritic stainless steel welds which improves joint strength.
However, this technique seems to alter the martensite distribution in the high-temperature heat affected zone (HTHAZ) which is a critical constituent in rating the susceptibility to sensitization Cited by: 1.

Hudson.The patterns in which atoms are arranged in the solid state determine properties. These arrangements can be manipulated by altering parameters such as the chemical composition, temperature and magnetic field. A phase transformation is a change in the pattern of atoms. We work on phase transformations and the relationship between structure and properties.
