Fine-grain high-density graphite blocks are extensively used for bearing and seals, particularly in high-temperature circumstances. This application is mostly due to the following characteristics of graphite materials; lubricating and frictional properties, high thermal conductivity, and high compressive strength at high temperatures. Fine Grain Practice - Metal and Metallurgy engineering Oct 06, 2005 · If carbon steel plates are supplied as fine grained with aluminum as the grain refiner, you will not develop coarse grains. Aluminum used for grain refinement forms oxides and nitrides that inhibit grain growth during processing. RE:Fine Grain Practice. TVP (Materials) 3 Oct 05 14:53.
High-Strength, Low-Alloy Steel This is a group of low-alloy steels with a very fine grain size with tensile yield strengths between 350 and 360 MPa. This is achieved by addition of small controlled amounts of Nb, Ti, or Va. 126.96.36.199.2 High-Alloy Steels Fine-grain Definition of Fine-grain by Merriam-WebsterFine-grain definition is - producing images of low graininess so that considerable enlargement without undue coarseness is permitted used of a photographic developer. Fine-grain structural steels, normalized rolled The series of normalized rolled fine-grain structural steels is characterized by a minimum yield strength of 275 - 355 MPa, by good weldability and high resistance to brittle fracture. These grades are used above all for manufacturing highly stressed welded structures in the construction of heavy machinery, bridges and steel structures.

US3375105A - Method for the production of fine grained Aluminum is most commonly used to produce fine grained steels because it is both effective and inexpensive. Normal aluminum additions for producing a fine grained plain carbon steel range from 1Normalised fine-grained structural steelsNormalised fine-grained structural steels are traditionally produced by means of heat treatment, so-called "normalising annealing", after rolling. This heat-soaking to above the ferrite-austenite transformation temperature and subsequent slow cooling generates a fine, regular ferritic-pearlitic microstructure in the steel.
