Specification AgeRangeDescription : adult Brand : USA Knifemaker Supply BulletPoint1 : When you order 1 quantity, you receive a 12" piece BulletPoint2 : CPM154 is tougher than S35VN but less wear resistant than S35VN or quite a bit less than S90V (which is well above average). The upside to CPM154 that it finishes beautifully. It takes flawless mirror finish with just a little effort. It is also tougher than S35VN so it can handle a very thin edge. This is a great candidate for a fillet knife. It is easy to sharpen, holds a nice, thin edge well and has great corrosion resistance. This steel could end up as your favorite knife steel. It is an enhanced version of ATS-34 using much better particle double vacuum foundry process. BulletPoint3 : It is important to note that this is surface ground, not precision ground. There is a difference. Surface grinding just removes the specified amount of surface material on both sides and gets close to the specified thickness. Precision ground is certified ground to a specified thickness and flatness. The more precise the specifications on surface grinding, the more expensive it is. BulletPoint4 : This CPM steel is designated at .075” thickness but we measure it to an average of .085” in thickness so it is slightly oversized, which is typical for CPM steels. This gives you a little room to remove any foundry surface imperfections but we don’t see any. We had this batch of steel “time saver” surface ground. That means all the foundry scale is removed and the metal is ground down to a bright metal surface instead of the typical gray foundry scale “bark” found on most CPM steels BulletPoint5 : WARN: Metal material, the edge is a little sharp, please be careful when use Color : Silver ExternallyAssignedProductIdentifier : 9471457248474 ExternallyAssignedProductIdentifier1 : 0616639523423 ExternallyAssignedProductIdentifier2 : 616639523423 GradeRating : Specialty ItemForm : Bar ItemName : Stainless Steel Bar- CPM154- Surface Ground- Stainless Steel for Knifemaking, Metalworking, Forging- 12" Piece (1, .103"x1") ItemPackageDimensions_Height : 1 centimeters ItemPackageDimensions_Length : 3 centimeters ItemPackageDimensions_Width : 2 centimeters ItemPackageQuantity : 1 ItemShape : Bar ItemTypeKeyword : stainless-steel-bars Manufacturer : Niagara Specialty Metals Material : Steel ModelName : ACFFVBW ModelNumber : ACFFVBW NumberOfBoxes : 1 NumberOfItems : 1 PartNumber : CPM154-sg ProductDescription : HR means hot rolled and this steel was rolled to thickness usually during the smelting process but maybe later. The steel generally will be half or nearly fully hard depending on the type. It may often have mill scale residue. This steel can be easily forged. It can also be ground via stock removal. Drilling a hole in the tang maybe hard to do with out a carbide bit. HRA is the same but the steel was later annealed to relieve stress and make it as soft as possible for easier machining. Several companies produce "powder" smelted steels. This is a premium smelting process that improves the mixing of alloy content and generally produces a finer grain structure as a result. The powder steels are nearly always annealed and can be assumed to annealed unless noted otherwise.
