Our company's sa709 grade 36 structural carbon steel power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the sa709 grade 36 structural carbon steel utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
The company has huge steel sa709 grade 36 structural carbon steel products stock all the year round to meet the urgent needs of customers. For stock products, we can arrange delivery within 3 days. The transportation department and shipping department shall coordinate and follow up to update the progress to customers regularly, i.e. where the goods have arrived, so as to let customers not worry and rest assured. Think about what the customers think and what the customers are anxious about, solve problems for customers efficiently and effectively, is the direction of our unremitting efforts.
Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium sa709 grade 36 structural carbon steel carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some sa709 grade 36 structural carbon steel alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
1200 tons API 5LGRB strips to Bangladesh. In December of 2015, we get one tender project from National Tubes Limited, which is a famous national enterprise in Bangladesh. It is an order of 1200 tons API 5L Gr. B steel strips, they bought these cargo to fabricate ERW pipe in local place.
40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. sa709 grade 36 structural carbon steel, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785
Group consciousness is an important psychological factor for the formation of enterprise internal cohesion. The formation of sa709 grade 36 structural carbon steel enterprise group consciousness makes every employee of the enterprise regard their work and behavior as an integral part of the realization of enterprise goals, make them feel proud of themselves as a member of the enterprise, have a sense of honor for the achievements of the enterprise, and thus regard the sa709 grade 36 structural carbon steel enterprise as the community and belonging of their own interests.
