The X80M pipeline steel customized by the company for customers will be supplied to a construction machinery manufacturing enterprise for making core components of rotary drilling rigs. Based on the original production process of high-end A633 Gr E material pipeline steel, the company formulated and optimized the process plan and production operation plan, strictly controlled the content of harmful elements in the production, optimized the rolling parameters and cooling mode, and ensured that all performance indexes of customized X80M A633 Gr E material pipeline steel met the requirements of customers.
When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials A633 Gr E material. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
The quality of A633 Gr E material shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of A633 Gr E material buyer, such as packaging, delivery time, etc.. On the basis of the quality of A633 Gr E material in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements. These requirements may be the control of chemical element content of A633 Gr E material and certain performance limit of A633 Gr E material, etc.
Chemical elements of 42SiMn steel: C: 0.39-0.45, Si: 1.10-1.40, Mn: 1.10-1.40. Mechanical properties of 42SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 40; impact energy: 47J. 42SiMn steel belongs to alloy quenched and tempered steel with good properties, high strength, wear resistance and hardenability. Under certain conditions, the strength, wear resistance and hot working performance of 42SiMn steel are better than 40Cr steel, A633 Gr E material, and can be used instead of 40CrNi steel.
We have built solid cooperation with Myanmar Navy since 2015, starting from a try order about 412 tons LR AH36 shipbuilding steel plates. Myanmar navy builds frigate every year and book shipbuilding steel materials from us regularly. This time, the Myanmar navy’s local representative visit us and put another order about 2025 tons LR grade A steel plates. According to clients requirements, we arranged A633 Gr E material SGS inspection for the LR grade A steel plates before shipping and send them inspection report.
We have a professional production team and high-quality production equipment, and we also have a great A633 Gr E material advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the A633 Gr E material production of high-quality steel plates, steel pipes and other products that meet customer requirements.
