New York Mall Womens Funny Lazy Halloween Pretend I'm An Apple Gift Women Men Why is this no longer Starrett manufactured steel Amazon??? This new steel didn't even have the manufacturer labeled anywhere on it!! They must not be very proud of their steel if they wont even put their name on it anywhere!! I used to get a nicely packaged beautifully precision ground piece of steel from Starrett. This time I received a poorly packaged piece of steel with a faded red "A2" stamped on it. Starrett package their steel with a wax coated paper packaging to keep out moisture. This no-name brand steel's package had holes ripped in it! When I opened the package the steel was not beautifully shinny and perfectly ground. There was a chip in one of the edges, and the steel was full of stains and had some minor pitting. SOME COOPERATE IDIOT AT AMAZON HAS OBVIOUSLY DECIDED TO PROVIDE CHEAPER, POORER QUALITY STEEL FOR THE SAME PRICE!What received was definitely Starrett precision ground a2 tool steel. The package was beaten up, and there are a couple of nicks, but I'm not trying to use a a straight edge.
I know that there are a lot of bad comments about the scale but those are from three years ago and I will tell you that it is now it is legit a2 steal that hardens in air
This is exactly what I had been looking for, and the size and quality are just perfect. And the price can't be beat, at least not anywhere else I looked. Definitely a steal for a steel.Exactly as described.Exactly as described. Hardens well.It very convenient and fortunate this size and exact dimensions are available in this particular steel. Thanks.This material is not A2 tool steel because:1. Starrett brand precision ground steel is clearly identified "Starrett" "Air Hardening" and with a distinctive parallelogram logo in blue ink stenciling and packaged in color coded and labeled plastic wrap. Granted it was not presented by Amazon to be Starrett or any other brand.2. The material was wrapped in brown paper with a faded xerox label stating "Starrett A2 steel". No other identification found. Should have heeded my gut instinct at this point.3. The most damming evidence that this material is not A2 because when it is quenched in OIL from 1750 F could be CUT with a file which means it is LESS THAN Rc58-Rc60.4. A2 quenched in still air, a less rigorous method than oil quench, yields a Rc63.5-Rc65hardness. A file will 'skate' across this degree of hardness.Too late to return it because the 'steel' has been fabricated to the point of hardening. Material for the metal recyclers.Please demand an explanation for this discrepancy from the vendor.

The A2 tool steel rectangular bar has been precision ground and annealed, meets American Society for Testing and Materials International ASTM A681 specifications, and has a precision tolerance. The A2 tool steel grade has better wear resistance than O1 and W1 tool steels, and maintains good dimensional stability when hardened in air following heat treatment. The bar has been ground to achieve the precise shape and size, and has been annealed, a method of heating and cooling metal to modify its properties, such as increasing its formability and toughness or decreasing its strength, after it has been shaped.
Steel is an iron alloy with carbon and other elements that modify the steel to achieve specific properties. In general, steels with higher carbon content have greater strength, hardness, and wear resistance, while those with lower carbon content have more formability, weldability, and toughness. Carbon steels, which include most AISI-SAE grades in the 1000 range, are classified by their level of carbon content as low (below 0.3%), medium (0.3% to 0.6%) and high (0.6% and above). Alloy steels, which include AISI-SAE grades in the 1300 and 4000 ranges and above, incorporate elements such as chromium, molybdenum, and nickel to modify properties like machinability and corrosion resistance. Tool steels, which include most grades with a letter and number grade designation, have high carbide content for wear resistance, high hardness, and the ability to hold a cutting edge. Some tool steels are designed to resist deformation when used in elevated temperatures.
Tensile strength, used to indicate a material’s overall strength, is the peak stress it can withstand before it breaks. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Toughness describes the material's ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Formability indicates how easily the material can be permanently shaped. Machinability describes how easily it can be cut, shaped, finished, or otherwise machined, while weldability characterizes the ability to be welded.
