The company needs "lion-type" entrepreneurial leaders who are full of entrepreneurial enthusiasm and dare to self-renovate. They also need a large number of professional and professional high-quality talents, and employees can get full capacity to display opportunities.

Whose hardness is higher between No.20 steel and No.45 steel, S355M steel plates? Both No.20 steel and No.45 steel belong to high-quality carbon structural steel. According to the characteristics of high-quality carbon structural steel, its carbon content determines the performance of the steel. The higher the carbon content, the higher the hardness and strength of the steel, the lower the plasticity and toughness. The carbon content of No.20 steel and No.45 steel are 0.20% and 0.45% respectively, which shows that the hardness of No.45 steel is higher under the same process.

The user of S355NC grade must make sure that his calculation, design and processing methods are appropriate for the S355M steel plates material. The forming process used must be suitable for the intended application and comply with the state-ofthe- art; it is of fundamental importance to the processing behaviour of this S355M steel plates steel grade.
