What is the S355nl VS S355ML impact toughness?

Manganese steel plate is subdivided according to material grade: Q345A, Q345B, Q345C, Q345D, Q345E, S355nl VS S355ML. 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.

S355nl VS S355ML, High-strength wear-resistant plates have outstanding performance advantages. First of all, the high-strength wear-resistant plates get their name because their wear resistance is very good, and the degree of wear will not be prominent. Secondly, the corrosion resistance of the high-strength wear-resistant plate is very good. General chemical plants have many corrosive liquids, and the high-strength wear-resistant plates can be used as the floor to reduce risk of accidents.

In actual processing applications, the processing S355nl VS S355ML thickness of flame cutting ranges from 6 to 200 mm, and the S355nl VS S355ML cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting S355nl VS S355ML with a certain thickness above 10mm.

BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For S355nl VS S355ML ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the S355nl VS S355ML standard requirements. The company is a good ASTM A572 Grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.
