Welcome to BBN High Strength Steels Factory
The yield strength of A40, D40, E40 and F40 S690QL hot rolled steel weight is not less than 390N/mm^2, and the tensile strength is 510~660N/mm^2. A, D, E and F respectively indicate that they can be at 0° and -20 ° respectively. Impact toughness S690QL hot rolled steel weight that can be achieved at -40℃, -60℃.
The alloy steel seamless pipe is a kind of product developed on the basis of traditional seamless steel pipe. Some characteristics of the S690QL hot rolled steel weight, alloy steel seamless pipe are also great progress and optimization based on the traditional seamless steel pipe products. Alloy steel seamless pipe is a kind of high performance seamless pipe. In industrial production, seamless pipe is usually used in pipeline engineering which needs to bear greater pressure.
we also provide the S690QL hot rolled steel weight welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful S690QL hot rolled steel weight welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.
The S690QL hot rolled steel weight 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 S690QL hot rolled steel weight ASTM A537 class 1 equivalent, 16Mo3 datasheet, Q245R material properties, Q345R material specification, P355GH properties, pressure vessel steel price, etc.
Our company regularly visits customers, consults and follows up the after-sales service, and directly solves problems for customers. In the use of our steel materials, whether quality problems or not, the after-sales will help solve the problem as soon as possible.
