1500*6000mm S690QL1 material equivalent

Chrome-Moly low alloy steel S690QL1 material equivalent series contains 0.5% - 9% Cr and 0.5% - 1% Mo and lower than 0.20% carbon. 40CrNiMoA, 4340 and SNCM439 are the low alloy chromoly steel materials from the different standards. 40CrNiMoA steel S690QL1 material equivalent is a Chinese standard chromium-molybdenum high strength steel with good hardenability and toughness.

The company adheres to the needs of customers, adheres to win-win integrity, and relies on scientific and technological innovation to continue to improve the level of logistics equipment technology and information technology, and enhance the logistics technology research and development and innovation capabilities. Based on market demand and innovation as the driving force for development, the company actively expands the field of logistics services, accelerates the extension of the logistics industry chain, and scientifically advances the diversification of the logistics industry.

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 S690QL1 material equivalent are higher than that of annealed S690QL1 material equivalent, but the elimination of internal stress is not as good as annealing. The normalizing operation of S690QL1 material equivalent is simple, the cost is low, the productivity is high, and it is widely used in actual production.

The Peru customer has cooperated with us since April 2015, and then they purchased 300 tons A36 mild steel plates as trial order. Since then, they book more than 1000 tons from us every time, and about two times every year. They asked SGS test every time. Through our cooperation those years, we have built very good relationship and they entrust us to buy other related S690QL1 material equivalent products for them from China also. And they have introduced us good customers in Peru, among which there are also governmental projects. It is a win-win cooperation between us.
