Shaped carbon steel welding of nm400 steel sheet

welding of NM400 steel sheet annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of welding of NM400 steel sheet annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. welding of NM400 steel sheet annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

The XAR500 is a special structural steel with high wear resistance. This wearable special-purpose structural steel has an average hardness of 500 HB, high hardness and good toughness, and the structure made of the steel is stronger, lighter and can withstand impact load. Uses for welding of NM400 steel sheet wear and tear - exposed structures such as shovels, shields for mining machines and bulldozers, shell walls, supports and stiffener, pavers and agricultural machinery.

Our quality control department will do inspection for details of the steel materials welding of NM400 steel sheet before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
