Quality requirements of EN steel grade S450J0 material

For employees' development,  the company's transformation and development provides employees with a broad career development platform. 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.

Grade EH36 marine steel: E is the quality grade E, H is the high-strength building material, 36 is the maximum compression, and Z is the Z-direction stretching. Grade EH36 structural steel for high-strength hull refers to the steel used for manufacturing the hull structure produced according to the requirements of the classification society. Our company mainly supply Grade EH36 hot rolled plate, EN steel grade S450J0 material, Grade EH36 angle steel bars and steel sections.

Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld EN steel grade S450J0 material steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for EN steel grade S450J0 material manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).

The carbon content of EN steel grade S450J0 material, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
