carbon content of NM400 biggest 5 mills in Iran

At the same time of doing well in carbon content of NM400 production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the carbon content of NM400 technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

We have carbon content of NM400 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. It indicates our carbon content of NM400 tank plates quality has been well recognized by Nigeria market.

316 Vs 304: ASTM 316L(1.4404) is a low-carbon austenitic chromium-nickel-molybdenum steel. Due to the addition of 2-2.5% molybdenum, the corrosion resistance of the stainless steel 316L is significantly better than that of the standard austenitic grades 304 and 304L, carbon content of NM400. The 1.4404 material is resistant to intercrystalline corrosion when welded! but not resistant to sea water. Best corrosion resistance is given with a polished surface. This material is comparable to 1.4401.

304 stainless steel plate products have strong corrosion resistance. For ordinary alkali solution and organic acid, inorganic acid has good corrosion resistance. This material carbon content of NM400 is a high alloy steel, which can resist corrosion in air or chemical corrosive medium.

With the development of multimodal transport in the international shipping market and the increase of the complexity of the integrated transport chain, modern ports, as the intersection of the three transportation modes of sea, land and air, are developing from traditional transfer and product distribution functions to all-round value-added services, becoming the central link connecting the world's production, exchange, distribution and consumption, and supporting the world economy and international trade An important part of the developed international circulation system.
