Coiling temperatures
Coiling temperature impact properties on the strip After finish rolling the strip, cooling water within the layer to change the coiling temperature range α is significantly suppressed. Under most eutectoid ferrite nucleation and growth in the coiling temperature, following the completion of extre...Read more -
Carbon steel and alloy steel comparison and selection principles
On many occasions people more choice of steel instead of carbon steel mainly has the following the aspects. (1) Poor hardenability Carbon steel use water quenching, its critical quenching diameter into 15 ~ 20mm, 20mm diameter greater than for parts, even if the water can not quench hardenability...Read more -
