S355J2 carbon steel plate sheet, vessel plate mill

The X80M pipeline steel customized by the company for customers will be supplied to a construction machinery manufacturing enterprise for making core components of rotary drilling rigs. Based on the original production process of high-end S355J2 carbon steel plate sheet pipeline steel, the company formulated and optimized the process plan and production operation plan, strictly controlled the content of harmful elements in the production, optimized the rolling parameters and cooling mode, and ensured that all performance indexes of customized X80M S355J2 carbon steel plate sheet pipeline steel met the requirements of customers.

S355J2 carbon steel plate sheet, Wear-resistant steel plates are easy to overheat, so pay attention to heating temperature and holding time. It is recommended to heat up to 820 degrees for proper insulation. Tempering temperature: 320 degrees, sufficient time. Hardness: 45-48HRC. Good performance. Salt bath NaCl:BaCl=3:7 can be heated at a temperature of 820, time is 30 seconds/mm (mm refers to the effective thickness of the part), oil cooling. Tempering temperature is 280, air furnace time is 2 hours, and nitrate furnace time is 30 minutes.

The toughness of steel such as S355J2 carbon steel plate sheet is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.

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”.
