What is S690QL1 1.8988 high strength steel coil steel grade

In today's S690QL1 1.8988 high strength steel coil steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of S690QL1 1.8988 high strength steel coil market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

Q345DR steel is a pressure vessel special plate with yield strength of 340MPa grade. It has good comprehensive mechanical properties and process performance. Phosphorus, sulfur content than ordinary 16Mn steel, in addition to tensile strength, elongation requirements than ordinary 16Mn steel has been improved, but also required to ensure impact toughness. S690QL1 1.8988 high strength steel coil was China's most widely used, the largest amount of pressure vessel special steel.

We have many kinds of boiler and pressure vessel steel materials, including ASTM, ASME, DIN, JIS, en, GB and other multinational standards, dozens of steel grades. Customers have a wide range of options. At the same time, we have obvious advantages in wide and thick plates. The widest boiler plate can be more than 5 meters. The S690QL1 1.8988 high strength steel coil and pressure vessel steel price is also competitive, and there is a professional team to serve you.

Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel such as toughness, plastic extension, forming, welding and cutting, abrasion, high temperature and fatigue. S690QL1 1.8988 high strength steel coil, Weathering steel sheets are used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.

20# seamless steel pipe chemical composition: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25. 20# seamless steel pipe mechanical properties: recommended heat treatment temperature: 910℃, tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%, impact energy is not required. 20# seamless steel pipe hardness is higher than 10# seamless steel pipe. S690QL1 1.8988 high strength steel coil, 20# seamless steel pipe has good weldability, no temper brittleness, and its machinability can be improved by water quenching. 20# seamless steel pipe can be used to make welded components, as well as parts with small load after forging, hot stamping and cutting.
