Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the CCS AH40 high tensile steel plate steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
According to the different manufacturing processes, there are hot rolled steel pipes and cold drawn CCS AH40 high tensile steel plate seamless steel pipes. BBN sells seamless pipes of different sizes, weights and grades. Customers can choose between black CCS AH40 high tensile steel plate line pipes and galvanized line pipes. From 2-3/8" to 24", steel grade A, B, X42, X80.
A small amount of Nb is sufficient to obtain excellent comprehensive properties of CCS AH40 high tensile steel plate etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
