Carbon steel pipes for cooling
Carbon steel pipe cooling method varies with the material. For most kinds of steel use natural cooling to meet the requirements. for certain special purpose steel pipe, in order to ensure the requirements of the organization of the state and physical and mechanical properties for certain special ...Read more -
Alloy Steels pipe
Stainless steels pipe contain a minimum of 11% chromium, often combined with nickel, to resist corrosion. Some stainless steels, such as the ferritic stainless steels are magnetic, while others, such as the austenitic, are nonmagnetic.Corrosion-resistant steels are abbreviated as CRES. Some more ...Read more -
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 -
