What is the difference between S420ML steel channel and ST37-2 material

We have new significant S420ML steel channel projects in Nigeria. It is about crude oil storage tanks. With the development of our steel materials business in the Africa those years, Nigeria has been an important market to us. And we have many S420ML steel channel famous projects in local and also participated in a lot of governmental projects. This crude oil storage tanks project is a very big engineering, and lasts for years. This is the only initial stage. We are under negotiation about following installation and further demands etc. matters.

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

Best quality of steel raw materials used (A516 Grade 60). Our structural steel plates and sheets are of high quality of work. Moreover, these are also highly repellent to erosion. These plates are also featured by the following properties. Incredible weld-ability of plates. Long-lasting boiler plates. Appropriate durability of the plates S420ML steel channel. Highly resistant to corrosion. Highly resistant to deterioration and lastly, precise finish.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the S420ML steel channel steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.

The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for S420ML steel channel.

we are the best professional steel manufacturer in China. We can supply kinds of steel product size，if you want to purchase steel plate or steel pipe and other products. Please contact us freely. we can give you the S420ML steel channel best price with high quality.
