9% Nickel Steel for LNG and Cryogenic Applications

Mar 21, 2018 · However, steel produced with 9% Nickel is different:it has an especially low brittle-ductile transition temperature, meaning that it remains ductile even when extremely cold. These properties, combined with 9% nickel steels high toughness and tensile strength, makes it perfect for the production, containment and storage of liquefied natural Controlling Hydrogen Embrittlement in Ultra-High temperature. The baking temperature for embrittlement relief is specified as 190-220'C for steels having tensile strength of 1000 MPa and higher (Table 1);19 thus, 190'C was selected for study. The amount of H desorbed during baking from each trap state was quantified by both electrochemical extraction and thermal desorption Heat Treat DrAlloy steel, which is susceptible to temper embrittlement, will exhibit a relationship such as shown below (Fig. 1). The lower-temperature energy trough, 250400°C (480°F 750°F), is indicative of tempered martensite embrittlement while the trough at the higher temperature, 450-650°C (840 1200°F), represents temper embrittlement.

Nitride embrittlement failures of carbon steel and low

Jun 01, 1997 · OSTI.GOV Journal Article:Nitride embrittlement failures of carbon steel and low-alloy steels Title:Nitride embrittlement failures of carbon steel and low-alloy steels Full Record Temper Embrittlement - Metal and Metallurgy engineering Jun 24, 2009 · Since the subject of temper embrittlement came up in the 4140 thread, I thought it might be useful to discuss temper embrittlement. I have worked in automotive and aerospace low alloy steel heat treatment and failure analysis for over 30 years and have never encountered a failure from temper embrittlement that I could document. The Embrittlement and Fracture of Steels:Part Two The optimum temperature range for temper embrittlement is between 500 and 575°C. However, in some steels embrittlement occurs in the range 250-400°C. This phenomenon is called 350° embrittlement, and occurs at too low a temperature to attribute it to the diffusion of metalloids such as Sb to the austenite grain boundaries.

What is temper embrittlement, and how can it be controlled

Plain carbon steels with less than 0.5% Mn are not susceptible to temper embrittlement. However, additions of Ni, Cr and Mn will cause greater susceptibility to temper embrittlement. Small additions of W and Mo can inhibit temper embrittlement, but this inhibition is reduced with greater additions.
