- 1ANNEALING (Heating the metal to just above the upper critical point, soaking at that temperature and then cooling very slowly in a furnace)Annealing, is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and to make it more workable. Metals are annealed to relieve internal stresses, and refine the grain structure. In an annealed state, steel has its lowest strength. In general annealing is the opposite of hardening.
- 2CHROMIUM NICKEL STEELS series 200/300Chromium nickel steels are corrosion-resistant steel known as 18-8. Nickel intensifies the hardening effect of heat treatment in steel.
- 3MALLEABILITYA metal which can be hammered, rolled or pressed into various shapes without cracking, or having some other detrimental effect is known as malleable.
- 4WHICH METALS TRANSFER HEAT THE EASIESTe
- 5What kind of cutting fluid should be used when drilling titanium(cooking lard) a vegetable based oil.
- 6Know what type of alloy should be used to rivet STAINLESS STEELA Monel (68% nickel/ 29% copper) alloy or stainless steel (18% Chromium/ 8% nickel) should be used when riveting stainless steel.
- 7How are ferrous metals classified? ( Society of Automotive Engineers)
- 8What is safety wire usually made from?Safety wire is usually made from stainless steel (chromium 18%, nickel 8%), INCONEL(Inconel is a family of austenitic nickel-chromium-based) and sometimes BRASS (copper and zinc)
- 9What materials are used and taken out of steel as it is being manufactured?PHOSPHOUROUS and SULFUR are removed
NICKEL
VANADIUM ([ven-NAY-dium)
CHROMIUM
MOLYBDENUM ( molob denim)
TITANIUM
manganese (to counteract sulfur)
TUNGSTEN
- 10DEFINE STRESSstress
- 11TIME AT TEMPERATURE ( SOAKING)the time metal is held at the specified temperature is measured from the time the coldest part of the metal reaches the minimum limit of the desired temperature range.
- 12DEFINE STRENGTHThe ability of a material to resist distortion/ deformation caused by an external force.
- 13FUSIBILITYFusibility is the ability of a metal to become liquid by the application of heat.
- 14ELASTIC LIMITSElastic limit is the amount of tensile strength a material is able to withstand without being permanently deformed and unable to return to its original size and configuration
