S690QL yield strength price forecast

13CrMo4-5 steel plate delivery status and production process is strictly produced according to EN10028-2 standard. Delivery status: normalizing + tempering, tempering. The 13CrMo4-5 alloy plates thickness below 100mm, it is normalizing + tempering; Thickness 100mm-150mm, the plate is delivered in normalizing + tempering or quenched and tempered;150mm-250mm is delivered in tempered condition. The requirements for flaw detection levels, and Z-direction functional requirements can also be added.

Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and S690QL yield strength resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, S690QL yield strength new materials, and promotes the competition of enterprises Struggle.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized S690QL yield strength are higher than that of annealed S690QL yield strength, but the elimination of internal stress is not as good as annealing. The normalizing operation of S690QL yield strength is simple, the cost is low, the productivity is high, and it is widely used in actual production.

With the increase of temperature, the yield limit of S690QL yield strength will decrease monotonically, but the tensile strength of S690QL yield strength will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of S690QL yield strength. Near the blue brittleness temperature, the S690QL yield strength strength increases and the plasticity decreases. The elongation and section shrinkage of S690QL yield strength increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
