Cause analysis of cracks in S355ML beam

Global S355ML beam crude steel production in March this year increased by 2.6 percent month on month and fell by six percent year on year to 147.1 million metric tons. accordina to the World Steel Association (worldsteel).In the first quarter of this year, global S355ML beam crude steel production decreased to 443.03 million mt, down 1.4 percent year on year。

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, S355ML beam and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.

Cold rolled steel sheet has high strength, high hardness, high surface finish and is generally thin plate, which can be used for stamping. The production process of S355ML beam, hot-rolled and cold-rolled steel plates is different. Hot rolled steel plate is rolled at high temperature, while cold rolled steel plate is rolled at normal temperature. Generally speaking, cold-rolled steel plate has better strength and hot-rolled steel plate has better ductility.

Using advanced logistics management, advanced models and management experience to increase the reliability of logistics operations and provide customers with 24/7 cargo management. On the premise of reducing transportation and management costs as much as possible, we provide customers with high-quality and efficient services; good business reputation has been recognized and supported by our customers.

"The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, S355ML beam tube.The extrusion method is to pierce the billet or ingot with a piercer, and then extrude it into a steel tube with an extruder. This method is less efficient than the cross rolling method and is suitable for the production of high-strength alloy steel tubes."

The S355ML beam pressure vessel steel plates are our featured products. We have supplied pressure vessel steel plates to tank manufactures, boiler makers, power plants and so on customers all over the world. We have online service for you at any time, welcome to contact and learn more information about pressure vessel steel, such as S355ML beam ASTM A537 class 1 equivalent, 16Mo3 datasheet, Q245R material properties, Q345R material specification, P355GH properties, pressure vessel steel price, etc.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
