At present, the precision stainless steel strips produced by most manufacturers have the characteristics of high temperature resistance, corrosion resistance, high strength, and long service life. However, if they are used in harsh environments for a long time, their service life will inevitably be shortened. Why do you say that? Let’s analyze it below .

The most difficult problem of 304 stainless steel plate welding is welding penetration and deformation. The 304 stainless steel plate has a small degree of restraint. It is subjected to local heating and cooling during the welding process? It forms uneven heating and cooling, and the weldment will produce uneven stress. And strain, when the longitudinal shortening of the weld seam exceeds a certain value on the edge of the thin plate, it will produce more serious wave-like deformation? It will affect the shape quality of the workpiece.

There are many grades of stainless steel. QIHONG Stainless provides stainless steel coils in the following grades: 304, 304L, 316 / 316L, 301Ann, 301QH, 301HH, 301FH, 302, 309, 310, 321, 330, 347, 409, 410, 430, 600, 625, etc.

Mirror stainless steel plates and brushed stainless steel plates have very high requirements for welding marks. Users generally require that no marks can be seen on the back after welding, which is difficult to achieve.

The development prospect of the 304 stainless steel industry is very good, because it brings more benefits to the enterprise when it is used, so it is favored by customers. In order to let everyone know more, let's talk about the use The precautions for 304 stainless steel hope to bring help to more people.

The causes of pitting and protrusions on the surface of precision stainless steel strips: 1) The rough rolling rolls are severely worn, and the finishing rolling work rolls are severely worn; 2) Broken rolls and foreign matter rolled into the strip;
