27.11.2014We are a Hard chrome plating and grinding company and are having issues achieving a very specific hardness for one of our customers. They are specifying a minimum hardness of HV1100-HV1250. The finished deposit is 0.003 thick. We have supplied 3 samples for Vickers microhardness testing and all have fallen short of HV1100.

12.10.2021Rockwell B is better for softer steel or relatively hard aluminum. For softer aluminum, you may need to use the Rockwell E scale (1/8-inch diameter ball with a 100 kg load) or the Rockwell F scale (1/16-inch diameter ball with a 60-kg load). Generally, the larger the indenter or the smaller the load, the better a scale will be for soft materials.

15.12.2000Usually vitrified wheels are used at speeds less than 6,500 surface feet per minute. At higher speeds, the vitrified bond may break. Organic bond wheels are generally the choice between 6,500 and 9,500 surface feet per minute. Working at higher speeds usually requires specially designed wheels for high speed grinding.

The Leeb hardness tester does not require a workbench. Its hardness sensor is as small as a pen and can be directly operated by hand. Whether it is large, heavy or complex geometries, it can be easily inspected. Another advantage of Leeb hardness is that the surface of the product is lightly damaged and sometimes used for a non-destructive test.

Grade refers to hardness, but not the hardness of the particles themselves — it refers instead to the strength of the bond holding the particles to the wheel. A wheel with a stronger bond typically has a longer life. A softer bond is designed to break down faster to maintain a consistent cut rate as new sharp grains take the place of worn ones. The letters N, R, S

Rockwell is a fast hardness test method developed for production control, with a direct readout, mainly used for metallic materials. The Rockwell hardness (HR) is calculated by measuring the depth of an indent after an indenter has been forced into the specimen material at a given load. Generally used for larger sample geometries

Nitriding steels are invariably hardened and tempered at high temperature to increase the strength and toughness of the core. The tempering temperature is at least 30 higher than the nitriding temperature, normally 600-675C. Steel now has sorbitic structure which is also good for machining. 2. Final Machining:

A good example of hardness is the diamond, which is one of the hardest substances on the planet. Scratching a diamond is virtually impossible due to this hardness. But if you smashed that same diamond using a sledgehammer, it would shatter – this is because it's not tough. Let's look at toughness next. Toughness

What is a Shore durometer? The Shore durometer is an instrument used for measuring the material's hardness, generally rubbers, elastomers, and polymers. The Shore A hardness measurement is called ''durometer''. Tests are carried out on cured rubber according to ASTM D2240, and on a complete O Ring according to ASTM D1414.

Hardness (antonym: softness) is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. In general, different materials differ in their hardness; for example hard metals such as titanium and beryllium are harder than soft metals such as sodium and metallic tin, or wood and common plastics.

Add a teaspoon of liquid dish soap to a plastic water bottle and fill it almost to the top with water. Close the lid and shake the bottle. If, after shaking, there are bubbles in the water, your water is relatively soft.
