When to paint structural carbon steel grade A36

We have structural carbon steel grade A36 new cooperation projects with NNPC (Nigerian National Petroleum Corporation). Through tender, we got new order about oil tank plates for NNPC, and the tank plates will be used to build large oil tanks. This is not the first time we cooperated with NNPC, but it means much more to us than first time cooperation.

What is the difference between 20G and 20# steel grade? The difference between 20G and 20# steel is very big. The chemical elements, mechanical properties, service environment and price of 20G and 20# steel are very different. structural carbon steel grade A36, 20G and 20# steel can not be compared. They are not of the same grade level, and can not be replaced by each other. 20# steel is high quality carbon structural steel, 20G steel is high pressure boiler steel. structural carbon steel grade A36, 20# steel does not bear pressure, while the use temperature of 20G steel is 450~480℃.

According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. structural carbon steel grade A36, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.

Bangladesh is an important market to us. We cooperated with the National Railway, the National Tubes Limited (NTL) and so on state-owned enterprises. They have tenders regularly. And we would participate the tenders with our local agents. We have been the winner of NTL tenders for many times. API 5L grade B steel strips are their needed structural carbon steel grade A36 materials. They have special chemical composition, tolerance and so on requirements. We can fully meet their demands and guarantee timely delivery.
