Answer to Question 1).If the carbon steel plates are supplied under an ASTM/ASME specification,refer to ASTM/ASME A-20/SA-20,which is a SpecificOne thing to keep in mind is the difference between austenitic or prior austenite grain size and ferritic grain size.So if the coupon is carburized as specified in SA 20,under micro examination what grain do we observe.Is it Austenitic impression or is it ferritIt is the prior austenitic grain size that you will be evaluating.bimoorthy,In answering your question No.2,ferrite grain coarsening will occur with subsequent annealing or heating slightly below the upper critStanweld mentions an interesting point.The data that I have from Physical Metallurgy Handbook by Sinha shows a step change in grain coarseningThanks a lot for the inputs.Now from the point of view of acceptance or rejection of the material 1) The material ordered is SA 516 Gr 60.ThickneYour first statement is key regarding acceptance or rejection.Please note SA-516 states and I quote; The steel shall be killed and shall conformFollow-up to answers for Question 3 and 4; 3).No.Normalizing is a heat treatment process and does not equate with fine grain practice.Fine grainKilled steel's grain sizeJul 10,2011DEFINITION OF FINE GRAIN PRACTICEApr 01,2003See more resultsPeople also askWhat is fine grain practice?What is fine grain practice?Fine Grain Practice.This is in connection with Carbon steel plates.Some specification calls for fine grain steel and specify that the grain size is to be checked as per E 112.2) Is it possible to take a fine grain (Fine grain Melting Practice material) to be subsequently heat treated and get a corse grain (By annealing).Fine Grain Practice - Metal and Metallurgy engineering - Eng-TipsAustenitic Grain-Size of Steel Metallurgy

4.Effects of Austenitic Grain-Size of Steels Generally,Tine grained steels (in cast,or wrought form) are preferred over coarse grained steels,because fine grained steels have better toughness for corresponding hardness and strength (Fig.2.15) at normal temperatures (definitely below the equi-cohesive temperatures).Best practices for using fine-grained permissions in Sep 27,2017·Fine-grained permissions can influence security on a SharePoint farm.Potential performance issues can occur when you use fine-grained permissions.The following information helps you address issues when an environment is experiencing issues that incorrect use or scale of fine-grained permissions might have caused.
