5 Ways Fine Austenitic Grain Size Affects Your Machine

Nov 24, 2009 · While Austenitic Grain Size is a result of chemistry (composition), the changes that it evokes in our process are a result of material structure and properties, not just the chemical 'ingredients.' Steel that is fully deoxidized and grain refined is more sound, less suseceptible to cracking and distorting, and more easily controlled in heat treat.

    Stressproof® (CF) High strength without heat treatment. Stress relieved. Readily machinable with minimum distortion. Niagara LaSalle Stressproof meets ASTM A311, Class B. Fatigue-Proof® (CF) Higher strength than Stressproof® achieved by mechanical working and thermal treatment. Eliminates need for heat treating and secondary operations Heat Treatment Procedure Qualification for Steel Castings Apr 29, 2004 · The need for a heat treatment qualification procedure that accounts for this variability during heat treatment is an important step toward heat treatment quality assurance. The variability in temperatures within a heat treatment furnace is one such variable that a foundry has more » to contend with in its day-to-day activity.

    Heat Treatment before vs after Machining - Machines

    Feb 23, 2005 · The amount of warpage you get from heat treating varies with the steel and process. As a rule, less warpage is more money. Barry1961. RE:Heat Treatment before vs after Machining. 2. mrainey (Industrial) 30 Nov 04 12:32. I used to do a lot of aerospace machining of thin-walled 4130, heat treated up to Rc38-Rc45.
