In 1045 steel plate, the '10' means a basic carbon steel and '45' designates the approximate carbon content. 1045 steel is included in the ASTM 830 (A830) family of specifications. A830 Grade 1045 hot rolled steel plate can be cut to various shapes, hammer forged and heat treated. 1A572 grade 55 ms steel coil product is mostly used where greater strength is required than lower carbon steels.

Medium and heavy plate is widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields. The surface quality of medium and heavy plate mainly refers to its surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plate. The surface quality of A572 grade 55 ms steel coil, medium and heavy plate not only affects the appearance of the products, but also reduces the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate.
A572 grade 55 ms steel coil Tianjin inventory: 7*2920*8200, 15*2992*10185, 40*3050*5800, 14*1950*10700, 50*2500*12000, 20.9*2851*7000, 16*2120*6080, 20*1950*9350, 26*2200*12000, 20*2933*7300, 12.5*2900*11000, 40*3050*4200, 20*1950*9750, 15*2992*10185, 16*2230*7650, 14*2150*8500, 50*2200*12000, 16*2120*6080, 70*2500*12000.
A small amount of Nb is sufficient to obtain excellent comprehensive properties of A572 grade 55 ms steel coil 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.
