The chemical composition near the grain boundaries of inconel steel products can be altered by the precipitationof chromium-rich grains. The resulting chromium-depleted regions at the grain boundaries make 4cr13 stainless steel products susceptible to intergranular anodic attack even in unstressed-conditions.
Specifying an inconel steel product implies a little over 12% Cr. Most stainless steels are based on the Fe-Cr-C Fe-Cr-Ni-C system, but there are also other important alloying elements.
Inconel steel products can exist in several crystal forms, the most common of which are body centered cubic (bcc) and face centered cubic (fcc). In pure iron, the fcc structure still exists between 910 and 1400 °C, this interval below and above the body-centered cubic structure up to the melting temperature of 1539 °C.
The importance of this stage of transformation in the metallurgy of inconel steel products cannot be overestimated. This transformation allows a wide range of microstructures to be achieved through controlled heat treatment. The nature is related to microstructure, mechanical properties, therefore, inconel steel products can be obtained in a very large range of strength, toughness and so on. Regular production of inconel steel 100 MPa over 1 GPA has a strong competitive strength. Therefore, the primary concern is the knowledge of the relative stability of the bcc and fcc structures of ferrous inconel steels.
Free Sample:
Q:Can you send samples?
A:Of course, we can send samples to all parts of the world, our samples are free, but customers need to bear the courier costs.
Quotation:
Q:What product information do I need to provide?
A:You need to provide the grade, width, thickness, coating and the number of tons you need to purchase.
Q:About product prices?
A:Prices vary from period to period due to cyclical changes in the price of raw materials.
