فورج‌های فولادی: طراحی، تولید، انتخاب، آزمایش و کاربرد، راهنمای ۵۳

Manual 53 is a comprehensive, in-depth publication that covers the full range and scope of steel forgings. Twenty-two comprehensive chapters discuss: • Background information on the classification of forgings according to the method of manufacture: • Importance of steel production methods in establishing the expected properties: • A critical review of over 60 ASTM forging standards covering applications as diverse as railroad and power generation equipment, pressure vessel components, and a wide range of general industrial equipment • The effect of various types of forging operations relative to soundness and application • Specialized nondestructive testing methods developed for forgings • Economic and quality factors regarding the choice between forgings and other steel product forms • Special considerations in the heat treatment of forgings • Pros and cons of the timing of machining and the effect of test specimen location on the anticipated mechanical properties of the forging • Surface treatments for enhancing forging performance and life • Forging flaws and examples of service problems Manual 53 is both a practical and vital resource for design engineers; purchasing managers; manufacturers of pressure vessels, turbines, and generators; metallurgical engineers; university professors, and lawyers. This Group Of Specifications Was Written To Address Forgings For Large Pressure Retaining Components, Whose Weight Would Normally Be Measured In Tons Rather Than Pounds, And Where A Wall Thickness Of 1 In. (25 Mm) Would Be Considered To Be Thinches As A Consequence, The Heat Treatment And Testing Requirements Both Mechanical And Nondestructive Are More Demanding Than Those Found In The Piping Fittings Standards.
