Three common cutting methods of S550 steel grade cutting

40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel S550 steel grade is good. It can be hardened to Ф28 ~ 60mm during water quenching and Ф15~40mm during oil quenching. When the hardness is HB174~229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.

The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by S550 steel grade metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the S550 steel grade steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.

we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.

If you are in the search of best quality of S550 steel grade structural steel plate then you have landed on the right place. These high quality structural steel plates are used for a long time as they have a long life due to their best and advance manufacturing techniques. These S550 steel grade plates are best and ideal for temperature rise work, high pressure and tank fabrication work where accurate & excellent toughness is required for better results. Welcome to our factory. We supply our products to all the leading industries and customers who are satisfied with our production and quality.
