Maintaining High Heat-Treatment Standards: Learning from the Medical-Device Industry The COVID-19 pandemic is still ongoing at the time of writing. SAT should be performed periodically or after any maintenance. maintain, under prescribed conditions, the carbon content of the steel exposed C). range and then cooling in air, to soften the metal. appearance and resistance to corrosion. a rate of heat abstraction high enough to prevent the formation of high-temperature We have received several inquiries regarding the heat treatment standards required for dunnage. A preliminary heat treatment used to prepare a material for a desired reaction Heat treatment is both kind to the planet and kind to your bottom line. and heavy sections. a solid solution of one or more compounds whose solubility decreases with decreasing softer than the surface layer or case, The term core is also used to designate the relatively soft central portion of exhibit Age Hardening. This specification covers the engineering requirements for heat treatment of aluminum alloy castings and for parts machined from castings. The limiting temperatures of the ranges depend on the composition of the alloy Carbonitriding: See Temper Carbon. Heikki Laurila is Product Marketing Manager at Beamex Oy Ab. Quenching oil and heat treatment fluids are designed for rapid or controlled cooling of steel or other metals as part of a hardening, tempering or other heat-treating process. Any process of increasing hardness of metal by suitable treatment, usually involving and operators of heat-treatment facilities lack the necessary knowledge and expertise to implement temperature measur-ing systems, conduct heat-treatment operations with appro-priate heat-treating schedules, and monitor heat-treatment processes to ensure that requirements are met. temperingandcoldtreatment.Chemicalcompositions,heattreatments,andsome properties and usesarepresentedforstructural steels,toolsteels,stainless and heat- resistingsteels, precipitation-hardenable stainlesssteels and nickel-maraging steels. Once certified, businesses that do not utilize a kiln on-site may use KD-HT kiln-dried heat-treated lumber for their crating and/or packaging needs. This is typically done by placing a reference thermocouple close to the thermocouple to be calibrated and comparing the read-out of the measurement loop to the reference. It is easy to understand that heat treatment is a process where you need to have a very good control of the process in order to assure that you get the required end product, especially since the products are mostly used by the aerospace industry. temperingandcoldtreatment.Chemicalcompositions,heattreatments,andsome properties and usesarepresentedforstructural steels,toolsteels,stainless and heat- resistingsteels, precipitation-hardenable stainlesssteels and nickel-maraging steels. We have received several inquiries regarding the heat treatment standards required for dunnage. alloy composition that freezes at constant temperature similar to a pure metal. Rapid cooling. Followed by revisions: revision A in 1987, B also in 1987, C in 1990 and D in 2005. and Materials, and the Society of Automotive Engineers. The “AMS” name in the standard is an abbreviation of “Aerospace Materials Specifications”. Brittleness: and on the rate of change of temperature, particularly during cooling.
