Surface heat treatment methods for S275NL carbon steel plate sheet

As the thickness and hardness of S275NL carbon steel plate sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the S275NL carbon steel plate sheet from cutting cracks, preheating should be carried out before S275NL carbon steel plate sheet cutting. Special attention should be paid to preheating to make the entire S275NL carbon steel plate sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole S275NL carbon steel plate sheet cannot be preheated, the partial preheating method can be used instead.

Special-shaped seamless pipe is the general term of seamless pipe with other cross-section shapes except circular pipe. According to the different shapes and sizes of steel pipe sections, it can be divided into equal wall thickness special-shaped seamless pipe (code D), unequal wall thickness special-shaped seamless pipe (code BD), variable diameter special-shaped seamless pipe (code BJ). S275NL carbon steel plate sheet. Special seamless pipe is widely used in all kinds of structural parts, tools and mechanical parts. Compared with the round pipe, the special-shaped pipe has larger inertia moment and section modulus, larger bending and torsion resistance, which can greatly reduce the structure weight and save steel.
