The temperature
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.
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.
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.
