We’ve explored the several types of metal that you could be supply from China on this weblog submit earlier than, however after you have sourced it, how do you examine the properties of metal to guarantee that it reaches your specs? Testing. That’s how…
Which exams ought to we carry out to examine the properties of metal?
There are a lot of the explanation why you could need to be certain of the properties of metal. Listed here are just a few examples associated to security:
- Will probably be made into the ropes of a suspension bridge.
- Will probably be fashioned and bolted into the wings of an plane.
- Will probably be rolled and welded right into a stress vessel.
There are a lot of different, extra mundane functions for which utilizing the appropriate alloy, which went by the appropriate therapies (if wanted), is sort of essential. (There are greater than 3,000 such grades.)
Tales about massive metal makers mendacity concerning the properties of their materials usually are not exceptional.
If that you must verify a number of the most essential bodily properties (particularly, tensile power, hardness, toughness, and its resistance to corrosion), these movies will probably be helpful.
This sequence of movies from our lead engineer Paul over on Sofeast.com will clarify a number of the widespread metal exams that you could be come throughout.
1. Metal Tensile Energy Testing
Tensile power is a measure of the power required earlier than a fabric, on this case, metal, breaks or fails. The video covers:
- Why metal tensile power is so essential
- How you can examine the tensile power of metal (following the ASTM A370 testing customary for mechanical testing and procedures of metal merchandise)
- How you can look at the tensile take a look at outcomes and what the information means
- The system used to find out the metal’s tensile power

2. Brinell & Vickers Metal Hardness Checks
Metal’s hardness signifies how effectively it’ll resist abrasion or harm by friction. There are two exams for this, and the video reveals:
- What the Brinell hardness take a look at is (tools, take a look at methodology, and system from ASTM E10)
- Which sorts of metal merchandise want the Brinell hardness take a look at
- What the Vickers hardness take a look at is (tools, take a look at methodology, and system EN ISO 6507)
- How you can apply HV values to metal
- Which take a look at is extra correct

3. Rockwell Metal Hardness Check
One other hardness take a look at that may aid you decide how effectively a selected metal grade will resist abrasion and friction. This video explores:
- What the Rockwell hardness take a look at is
- The scales utilized in this sort of testing
- The operation steps for when performing the take a look at
- How you can use the Rockwell hardness equation to calculate the metal’s hardness (HRC)
- An instance of the take a look at setup
- Some widespread Rockwell hardness values for metal merchandise you could be conversant in together with their HRCs

4. Metal Toughness Testing
Metal’s toughness demonstrates its skill to withstand fracturing underneath power, as an illustration, if it may possibly bend or take a hammer blow and retain its integrity then it’s powerful. We cowl:
- The distinction between metal toughness and metal power
- How you can calculate metal toughness utilizing a Charpy V-notch take a look at (CVN) with the power required measured in Joules
- The results of temperature on affect toughness and power
Watch the video about metal toughness testing right here.
5. Metal Corrosion Testing
Metal is commonly utilized in functions the place it’ll come into contact with water, comparable to in a constructing’s foundations, maybe. In these instances, corrosion resistance is a key high quality to check for. The video explores:
- What the ‘salt spray take a look at’ (ASTM B117 or ISO 9227) is and an summary of its course of
- How you can examine an merchandise’s corrosion resistance following the take a look at
- The results of corrosion to look out for

Conclusion
We belief that these movies provide you with a useful introduction to how one can examine the properties of metal. By the way in which, we’re gathering all these movies about manufacturing supplies and processes in a library on our business web site, Sofeast.com.
What different processes or supplies do you usually work with? Do you have got any questions on metal testing? Let me know by commenting, please.
P.S.
When you’d prefer to be taught much more about metal alloys, check out these movies that discover the several types of metal, metal alloys, their makes use of, and many others.
