How to distinguish the normal floating rust and rusting of S420M datenblatt

The company adopts the S420M datenblatt international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety S420M datenblatt management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

Steel plates for oil and gas pipelines: X42 (L290), X46 (L320), X52 (L360), X56 (L390), X60 (L415), X65 (L450), X70 (L485), X80. Executive standard: API -5LB (L245). Main purpose: used to make oil and natural gas pipelines. API 5L generally refers to the pipeline steel plate-API 5L pipeline steel plate. The pipeline steel plate is processed into large-diameter pipeline steel pipe to transport the oil, gas, and water extracted from the ground through the pipeline pipe to the oil and natural gas industrial enterprises.

Grade E, Grade EH32, Grade EH36 series shipbuilding steel products have good comprehensive mechanical properties, welding performance, process performance. Our shipbuilding steel plate and S420M datenblatt steel sections are suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities in ocean, coastal and inland navigation areas.

Composition characteristics of low alloy structural steel, S420M datenblatt: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.

Q235 is a kind of carbon steel. S420M datenblatt, Q235 steel is widely used in steel structure construction because of its good toughness, good plasticity, certain elongation, good welding performance and heating performance. Q235A steel plate contains C ≤ 0.22%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.050, P ≤ 0.045. Q235B steel plate contains C ≤ 0.20%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.045, P ≤ 0.045. Q235C steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.040, P ≤ 0.040. Q235D steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.035, P ≤ 0.035.

Our company stocks a wide range of hot rolled carbon steel plate distributed globally from our service centers in the U.S., Canada, Mexico, U.K, France, Shanghai, and Singapore. Customers calling for S420M datenblatt A516 a lot of times are also trying to get their arms around forecast issues. As our customers continue to work on their forecasts, IRON & Steel has options to help you conduct structured forecast reviews and put inventory strategies in place to effectively manage any impact from forecast variability.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
