The strength indexes of s355 steel grade pipeline steel mainly include tensile strength and yield strength. At the same time, the yield strength ratio (yield strength to tensile strength ratio) of pipeline steel is also required, which is generally in the range of 0.85-0.93. Pipeline steel shall have enough high impact toughness (crack initiation and crack arrest toughness). For the base metal, when the toughness of the s355 steel grade material meets the requirements of crack arrest, its toughness generally can also meet the requirements of crack prevention.

Q245R boiler steel plate introduction: Q is the first letter of "Qu" Chinese Pinyin; Number 245 is the yield strength value; R: is the first character of "Rong" Chinese Pinyin. Q245R steel is a special plate for pressure vessels and boilers with a yield strength of 245MPa. It has outstanding mechanical properties and processability. If you have special requirements, our company can supply Z15, Z25, Z35 and other Z performance tests.

Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the s355 steel grade plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.

If you are in the search of best quality of s355 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.
