Disclosed herein are iron-based alloys having a microstruclure comprising a fine-grained ferritic matrix and having a 60+ Rockwell C surface, wherein the ferritic matrix comprises <10μm carbide precipitates.
It is five times greater than a ferritic matrix, eight times greater than a perlitic matrix and 50 times that of iron carbide.
The use of permanent mold grey iron allows very large productivity gains at our customers, due to the fine lamellar graphite structure and its ferritic matrix.
During soft annealing of a pearlitic steel structure the cementite lamellae will spheroidise creating small round cementite particles in a soft ferritic matrix.
The use of permanent mold grey iron allows very large productivity gains at our customers, due to the fine lamellar graphite structure and its ferritic matrix.
The second group deals with solid-solution strengthened ferritic grades.
The inventive method consists in preparing dense materials comprising a soft ferrite matrix with a second dispersed phase of zirconia particles, at a concentration of between 0.5 and 50 % by volume, by liquid process.
The present invention relates to a stainless steel alloy, closer determined a duplex stainless steel alloy with ferritic-austenitic matrix and with high resistance to corrosion in combination with good structural stability.
