Case Studies of Corrosion Failures

Oct 16, 2017 · Presenter:Wayne Niemeyer, Senior Research Scientist, McCrone Associates Corrosion of metals resulting in some sort of a failure mode has been a constant challenge for decades. Corrosion attack can take several forms; this presentation discusses two interesting materials failure analysis case studies:a severe intergranular corrosion attack on stainless steel tubing resulting in catastrophic Engineering Failure Analysis - ResearchGateEngineering Failure Analysis publishes original, high quality research papers, communications, and occasional review articles describing the analysis of engineering failures and related studies.

Failure Analysis of Corrosion on Stainless Steel Fasteners

Aug 01, 2017 · Analysis of CORRODED STAINLESS STEEL BOLTS Summary:Metallurgical Technologies, Inc. (MTi) received five stainless steel bolts from a marine environment. The bolts exhibited corrosion predominantly on the head of the bolt around the set screw, underneath the head of the bolt, and in the threads. MTi was requested to determine the cause of the [] Failure analysis of a bridge crane shaft - ResearchGatePage 1 of 18 Accepted Manuscript Failure analysis of a bridge crane shaft O.A. Zambrano, J.J.

Failure of a Martensitic Stainless Steel Ball Valve

Repeated failures of high-pressure ball valves were reported in a chemical plant. The ball valves were made of AFNOR Z30C13 martensitic stainless steel. Initial examination of the valves showed that failure occurred in a weld at the ball/stem junction end of austenitic stainless steel sleeves that had been welded to the valve stem at both ends. Intergranular Cracking and Failure of Stainless Steel Intergranular Cracking and Failure of Stainless Steel Vanes from a Closed, Riveted Impeller and finally failed by intergranular cracking. Use of type 410 martensitic stainless steel was recommended. You do not currently have access to this chapter. Riveted Impeller, Handbook of Case Histories in Failure Analysis, Vol 1, Edited By Khlefa MX3D Bridge MX3DMX3D is to 3D print a steel bridge in Amsterdam. After a challenging 18 month-long process of engineering, designing, re-engineering, re-designing, discovering the world behind permits, safety measures, canal wall renovation, re-designing, programming, fundraising, test printing, re-designing and re-programming, the actual printing of the bridge has finally started.

Martensitic Stainless Steel - an overview ScienceDirect Martensitic Stainless Steel. Martensitic SS have a body-centered tetragonal crystal structure. The Cr content in martensitic SS varies from 10.5% to 18%, and the carbon content can be greater than 1.2%. The amount of Cr and C are adjusted in such a way that a martensitic structure is obtained. Martensitic Stainless Steels ::Total Materia ArticleFigure 1:Microstructure image of a martensitic stainless steel. In order to obtain a useful property profile martensitic stainless steels are normally used in the hardened and tempered condition. The hardening treatment consists of heating to a high temperature in order to produce an austenitic structure with carbon in solid solution followed Metallography of stainless steel insight StruersLearn all you need to know about the metallography of stainless steel from information on the microstructure of stainless steels to guidelines on the metallographic preparation of stainless steels with expertise and insight from Struers, the worlds leading materialographic and metallographic experts.

Online publication date:1-Jan-1987. stainless steel Types & Facts BritannicaStainless steel, any one of a group of alloy steels usually containing 10 to 30 percent chromium. In conjunction with low carbon content, chromium imparts remarkable resistance to corrosion and heat. Other elements may be added to increase resistance to Failure analysis of martensitic stainless steel bridge Paper Cis aimed at finding the likely failure mechanism of a bridge roller bearing made of high strength martensitic stainless steel. Spectroscopy and finite element stress analysis of the roller indicated that an initial radial surface crack, found at an end face of the roller and close to the contact region, was induced by stress corrosion cracking (SCC).
