Good news: The largest steel importer in Nigeria ordered 4068 tons API 5L X52Q PSL2 3LPE seamless pipes and also ordered 8 pcs 42699.6 m³big diameter Crude oil storage doom roof tank in A537CL2 steel grade. In Sep 2019, This Nigeria client visited our company and factory, they were very satisfied with our company's quality control,production capacity and service. We also have reached a agreement for Phase II Project, It is also with another 10,000 tons APl 5L X52Q PSL2 3LPE seamless pipes.
Steel cutting treatment BBN STEEL can cut various machine tool side plates, special-shaped parts, flanges, bearing seats, embedded parts and other supporting materials for various mechanical engineering, pressure vessels and other supporting materials according to customer drawings, and undertake all kinds of steel plate processing services. High-strength low-alloy plate series, normal carbon plate series, die steel series, boiler and pressure vessel steel, API 5L PSL1 X42 specification, pipeline steel, wind power steel, wear-resistant steel and other high-end steel plates.
The quenching of steel plate is to heat the API 5L PSL1 X42 specification steel to above the critical temperature, keep it warm for a period of time, and then quickly put it into the quenching agent, so that its temperature drops suddenly, and the speed of rapid cooling is greater than the critical cooling rate, and obtain the heat treatment method of imbalanced structure with martensite as the main body. Quenching increases the strength and hardness of steel, but reduces its plasticity. Quenching commonly used quenching agents are: water, oil, alkaline water and salt solutions.
By Region: data shows that in the first quarter of Asia, crude steel API 5L PSL1 X42 specification production was 315.2 million tons, down 0.3% year on year. Crude steel production in the EU region in the first quarter was 38.3 million tons, down 10.0% year on year. The output of crude steel in North America in the first quarter was 29.5 million tons, down 4.0% year on year.
