Carbon steel has several structures such as ferrite, pearlite, and martensite depending on how the carbon is distributed in the material. Contact us for a quote. Subscription pricing is determined by: We have no amendments or corrections for this standard. High magnification optical microscopy and sometimes scanning electron microscopy SEM is required to reveal important details.
As the voice of the U. Forgings often show elongation of individual grains which indicate the orientation and flow of the material. Our laboratory also provides laboratory services for plastic testingmetal testingrubber testingoil testingpaint testingplating testingadhesive testingcircuit board testingand other testing. ASTM E is a method of etching a metal sample to reveal its microstructure. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
APM Testing provides A2LA accredited services for metal microstructure testing at a fair price, with prompt delivery, and a detailed test report. Safety precautions and miscellaneous information are also included.

Alloying elements in the metal sometimes separate into microscopic particles with distinct shapes. Please first verify your email before subscribing to alerts.
An experienced metallurgist is required to interpret the images created. It is the responsibility of the user of this standard to r407 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Microstructural results are typically reported as pictures of the microstructure along with a paragraph interpreting the meaning of the structure.

For specific cautionary statements, see 6. Add to Alert PDF.
Differences in microstructure are important because they can help to determine if a metal has been subjected to corrosive chemicals, is softer or harder at the surface, has been deformed, was welded properly, or has been over-heated.
