Welcome to BBN High Strength Steels Factory
Our quality control department will do inspection for details of the steel materials S690QL steel properties before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
IS 2062 E450 BR plates which have the quality of good tensile strength, excellent thickness, good elongation, good yield strength. We provide high-end finished products which have accurate dimensions, good durability i.e complete customer satisfaction. Our S690QL steel properties plates have different applications in a number of industries such as paper, chemical, natural gas, cement industries, oils, shipbuilding etc.
The advantages of flame cutting are simple cutting and low cost. The disadvantage of flame cutting is that when cutting thin plates, cutting deformation problems are prone to occur, and the materials that can be cut have certain limitations. The advantage of CNC cutting is that it can cut S690QL steel properties and any complex parts with high cutting accuracy. The disadvantage of CNC cutting is that there are certain operational and technical requirements.
The chemical composition difference between S690QL steel properties, Q235B and 20# steel is as follows: The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%. The difference of mechanical properties between S690QL steel properties, Q235B and 20# steel is as follows: The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.
With the continuous development of foreign business, our company has achieved pleasant cooperation with a number of freight companies, including international air transport (including international express) and sea bulk cargo, we can provide the best service. In order to better develop the air transport from mainland to foreign countries, so that the goods can be transferred in Hong Kong in a timely manner.
The company has a high-quality management, technology and R&D team, and adopts independent research and development, domestic innovative process optimization combination. Relying on advanced manufacturing technology and sophisticated production testing equipment, it has ensured the high quality of products S690QL steel properties and won a good reputation. We can offer various kinds of steel materials in GB, ASME, ASTM, JIS, DIN, EN, API standards and specifications.
