How to Check Whether the Material Meets the Standard

2022-09-16 15:05

Stellite alloy is a kind of cobalt-based alloy, because of the high price of raw material cobalt, and stellite alloy is much harder to process, so the price of stellite is higher than normal stainless steel alloy.

Usually some of customers will feel that the price is high when inquire stellite us about products. There are also some customers only know they use stellite alloy, but they do not know the stellite grade, so they will send us samples to test because some customers have no way to detect ingredients through chemical analysis. 

Several days ago, we received a samples 'stellite 20' valve seat to test the size and supply, but we test the material, that is not stellite 20, balance chemical composition is Fe.

Then how to test whether the material meets the standard?

  • test density

  • test hardness

  • handheld spectrometer

  • sample trial

Standard stellite chemical composition is show in another atricle.

If the products density, hardness and components controlled by spectroscopy are all qualified, the it must meet the standard.

Another way is to do a sample trial. If the sample can meet your using enviroment and requirements, that must be a good products.

SYTOP can supply samples for trial, can supply the viedo of testing. Any questions pls send us message.
