Low-alloy steel plate

Product Description

Low-alloy steel plate mainly includes: Q***-Q**5A It is a steel material, a kind of low-alloy steel(C<0.2%) and widely used in bridges, vehicles, ships, construction, pressure vessels, various types of construction machinery, such as mining and drilling rig used in various types of construction, power shovel, power-driven wheel anti-trolley, truck, excavators, loaders, bulldozers, various cranes, mining hydraulic support and other mechanical equipment as well as structure members. Q represents the yield of the material, and the following number **5 refers to the value of this material which is about **5 and will reduce with the increase of its material thickness. Q**5A?Q**5B?Q**5C?Q**5D?Q**5E are distinguished by the grade, mainly representing the different temperature of impact. Q**5A is not made to impact, Q**5B is *0 degrees room temperature impact, Q**5C is 0 degree impact, Q**5D is **0 degrees shock, and Q**5E is **0 degrees impact. Different temperature can result in different value of impact. It belongs to series of low-alloy steel plate and in the low-alloy material, such material is the most common. A popular name of Q**5 in the past was *6Mn. Executive standard: GB/T********8; specifications: thickness ****0mm.
