How much is equivalent grades of nm450 steel cost per square foot

Manganese steel plate is subdivided according to material grade: Q345A, Q345B, Q345C, Q345D, Q345E, equivalent grades of NM450 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,equivalent grades of NM450 steel.

45# steel is commonly used medium carbon quenched and tempered structural steel. The steel is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained 45# steel normalizing can improve the cutting performance of roughness less than 160HBS,equivalent grades of NM450 steel.

Laser cutting has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.
