Which Steels are Easiest (and Most Difficult) to Forge

Apr 29,2019 Warm forming of stainless steels#0183;High alloy steels are more difficult to forge because they have carbides present at high temperature that increase the stress required for forming the steel and decrease hot ductility.Excessively high temperatures in forging should be avoided because grain boundary melting and carbide coarsening can occur leading to poor hot ductility.Warm forming of stainless steels ExperimentsWarm forming of stainless steels Part II Simulations and experiments R4 40 44.6 R6 Punch Shoulder Radius Punch Diameter 4 40 Die Shoulder Radius Die Inner Diameter 6 44.6 All dimensions in mm.Insulation Plate Die Ring Heaters Blank Holder Water Inlet Sheet Punch Cushion Pins Figure 1 The die and the blank holder were heated through cartridge Warm forming of stainless steels - Part IIEditor's Note This article is Part II in a two-part series on warm forming stainless steel.Part II discusses simulation and experimental studies conducted by the ERC/NSM on formability of stainless steel at elevated temperatures.Part I discussed the rationale for and previous work on warm forming of stainless steels.

Warm forming of stainless steels - Part I

Studies on Stainless Steel Warm Forming.Previous studies by Shinagawa and Takuda indicate that warm forming of stainless steel sheet reduces martensite formation when forming at elevated temperatures.2,3 These researchers performed drawing tests of cylindrical cups made of types 304 and 316 stainless steel.Figure 1 shows the experimental setup used by Takuda.The Forming Potential of Stainless SteelAlternatively,stainless steels forming capacity allows two-piece designs (right-hand example),composed of two identical deep drawn halves.This design is preferable when reduction of welds is the driving parameter.Apart from its forming potential,stainless steelStainless Steels Alloys Formability,Fabrication and May 19,2005 Warm forming of stainless steels#0183;Unlike carbon steels,work hardening rates for stainless steel mean that more severe deformation is possible at slower forming speeds.For forming operations normally performed at high speed,like cold heading,it is recommended that the process is slowed.

How to Clean Stainless Steel That Is Discolored From Heat

Use a stainless steel polish to remove stuck-on stains such as food,tar and surface scratches from the surface of stainless steel.These cleaners are sold at most home supply or hardware stores,and contain tiny abrasives that lightly scratch the surface of the stainless steel which removes the contaminants from the surface and leaves the metal shiny.How stainless steel is made - material,manufacture,used The initial steel shapesblooms,billets,slabs,etc.are hot rolled into bar,wire,sheet,strip,and plate.Depending on the form,the steel then undergoes further rolling steps (both hot and cold rolling),heat treatment (annealing),descaling Ito remove buildup),and polishing to produce the finished stainless steel.How heat treating and annealing stainless steel impacts Austenitic stainless steels cannot harden via heat treatment.Instead,these steels work harden (they attain hardness during their manufacture and formation).Annealing these stainless steels softens them,adds ductility and imparts improved corrosion resistance.300-series stainless steels are the most popular examples of this type.
