Manganese steel plate is subdivided according to material grade: Q345A, Q345B, Q345C, Q345D, Q345E, A514 grade B quenched and tempered steel. The main differences according to the classification are as follows: A needs no impact test, B needs room temperature impact test (20 degrees above zero), C needs zero degree impact test, D needs minus 20 degree impact test, and E needs minus 40 degree impact test. The most important characteristic of manganese steel plate is that under the condition of strong impact and extrusion, the surface layer rapidly hardens, but the core still maintains good toughness and plasticity, and the hardened layer has good wear resistance.
A514 grade B quenched and tempered steel, Q345 steel has good comprehensive mechanical properties. Q345 steel also has acceptable low temperature performance, good plasticity and weldability. Q345 steel can be used as structures, mechanical parts, building structures and general metal structures bearing dynamic loads such as medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations and bridges. Q345 steel can be used in hot rolling or normalizing state, and can be used in various structures in cold regions below - 40 ℃.
The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by A514 grade B quenched and tempered steel metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the A514 grade B quenched and tempered steel steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.
We are engaged in A514 grade B quenched and tempered steel corten steel, weathering steel, atmosphere corrosion resistant steel materials. After receiving your inquiry about the weathering steel, we will make quotation for you at the first time. Meanwhile, our professional team can give you valuable answers about all kinds of question about the weathering steel. For example, corten steel cost per square foot, S355J2WP equivalent, A514 grade B quenched and tempered steel ASTM A242 steel properties, A588 steel yield strength, etc. If you have any demands or questions about weathering steel, please feel free to contact us.
