Product Guide - Steel Plate (contd)OVERVIEWCold Reduced PlateFlatness Defect Causes Pricing Considerations Higher in quality (surface, flatness and shape).Maintains flatness after shearing, burning, or laser cutting and lower in cost.Uneven coolingNon-uniform thicknessHow will it be released?Can customer accept scant cut?Is grain direction important?TERMINOLOGYCold ReducedDiscrete PlateInside Bend RadiusA rolling process that suppresses yield point elongation which eliminates coil breaks when decoilingReserved for heavier thicknesses, discrete plate is rolled from slabs directly into plate, never being coiledfirst. (see Strip Mill Plate)During the fabrication of parts made from flat rolled steel products (sheet/plate), some of these partsrequire the steel to be formed (bent) into different angles (examples 45 degrees, 90 degrees). This isusually done with the use of a “press brake”. The steel is forced down over a “nose die” which has a curvedshape. This shape forms the inside of the bend angle. The actual curvature of this die will vary, dependingon how sharp the inside radius of the bend has to be. This is known as the “INSIDE BEND RADIUS”. Thesmaller the “IBR” the more the steel has to stretch to make the bend.Different steel grades, having different strengths and different ductilities, will react differently duringbending. The same inside bend radius cannot be used for all steel grades. There are inside bend radiusrecommendations listed for some of the steel grades that we stock. They are shown in relation to thematerial thickness. For example, using a ¼” steel plate, an IBR recommendation of 1.5T would equal aninside bend radius of 3/8” (.250 x 1.5 .375)Integrated MillProduct produced from a BOF (Basic Oxygen Furnace)Mini MillProduct from Electric Arc FurnacePlateFlat rolled finished steel products within the following: .180” or thicker over 48” or .230” or thicker over 8”Strip Mill PlateStrip mill plate is leveled from coil. This process cannot be applied with heavier thicknesses (see DiscretePlate)A temper mill is a steel sheet and/or steel plate processing line composed of a horizontal pass cold rollingmill stand.Goal is to correct shape differences along the width of the coil through cold forming. The endresults/advantages of temper passing and leveling are listed below.Temper Pass Thickness dimension more consistent across the width Improved flatness Suppression of yield point elongation (from the temper pass) results in improved dimensional stabilityduring fabrication (product remains flat after cutting) Improved surface finish Slight increase in yield strengthForm 1254 3/16/05 (Reprinted 5/27/15)Page 3 of 4

ProductSTEEL SHEETProduct GuideOVERVIEWSheet products are stocked at CS&W in a variety of grades and thicknesses. They also have different end uses and advantages. Theseitems can be further processed from the original mill coil by cutting to length, slitting, blanking and in sheet form they can be sheared.For explanations of temper pass and inside bend radius, see Plate section, p. 3.For processing capabilities – See “Processing & Packaging” section.GENERAL CHARACTERISTICS & END USESMaterialSize Range (in.)Purchasing SpecificationCommentsHOT ROLLEDASTM A 1011CS Type B.071 - .171 x 36 - 72Temper rolled, .10% maxcarbon, cold reducedP&OASTM A 1011 CSType B.071 - .185 x 36 - 72Temper rolled, .10% maxcarbon, cold reduced,mill (HCL) pickling.SCSASTM A 1011 CSType BTemper rolled, .10% max.071 - .185 x 36 - 72* cold reduced, SCS finish(see comments)**AISI / SAE 1050.071 - .171 x 36 - 72Temper rolled, fine grainpractice.
