hardnes of hardox 500 sheet hardness

S355G10 + M steel plate is for marine engineering. "S" indicates structural steel, "355" indicates minimum yield strength of steel plate, and "G10" indicates mechanical function test that imitates post-weld heat treatment. "M" indicates control rolling. S355G10 + M plate is structural steel for marine engineering and belongs to European standard high-strength structural steel. S355G10 + M steel plate has good mechanical function, welding function and technological function.

Standing at a new historical starting point, we adapt to the requirements of supply side hardnes of HARDOX 500 sheet structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading hardnes of HARDOX 500 sheet steel materials supplier.

Ultrasonic flaw detection emits ultrasonic waves to the hardnes of HARDOX 500 sheet steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the hardnes of HARDOX 500 sheet steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.

Chromium element (Cr element) can improve the strength and hardness of hardnes of HARDOX 500 sheet, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the hardnes of HARDOX 500 sheet principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
