The basic principle of GL-DH 40 oil platform engineering steel, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.
How much is the marine steel price per ton?According to the difference of quality grade and strength grade, as well as the difference of plate size, production area, and user requirement, the price of GL-DH 40 oil platform engineering steel plate fluctuates greatly. At present, the market price of marine plate is about 3800 yuan per ton to 5800 yuan per ton. Generally, the most commonly used marine plate price is about 4000 yuan per ton.
According to foreign media reports, despite the impact of the coronavirus epidemic, most German screw GL-DH 40 oil platform engineering steel steel producers still maintain a good level of production. This is in sharp contrast to the situation in other European countries and Germany's domestic steel mills, which are suffering from a slowdown due to the spread of the epidemic. Lotter kummatt Stahl, a local distributor, told customers on its website: "there is no reason at present to believe that German steel mills such as Riva and ferralpi are no longer able to serve the GL-DH 40 oil platform engineering steel market due to the impact of the closure of local steel mills in Italy.
The Metals Industry Organization last week discussed two things on the Article 232 of the U.S. Trade Expansion Act of 1962 “25% and 10% tariffs on imported GL-DH 40 oil platform engineering steel, steel and aluminum products, respectively”implemented in March 2018, and CBP - US Customs and Border Protection Administrative Office considered to delay the payment of import tariffs.
