We are world class steel materials supplier. We are engaed in providing raw steel materials such as A514 grade Q quenched and tempered steel steel plates / steel coils / steel sheets / steel pipes, deep processing and a series project design and solutions to clients. We guarantee to return goods for free for quality problem during its lifetime. Your satisfactory is our permanent pursue. We always welcome advise from clients to make self-improvement continously. And sincerely to build A514 grade Q quenched and tempered steel long-term cooperation with you.
Grade AH32/AH36, A514 grade Q quenched and tempered steel, Grade DH32/DH36 high-strength structural steel products for hulls have good comprehensive mechanical properties, welding performance, good processing performance. Grade AH32/AH36 hull strucural steel is suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities, etc. in ocean, coastal and inland navigation areas.
Advantages of A514 grade Q quenched and tempered steel, ordinary carbon killed steel plate: there is no gas in the steel plate, the impurity is relatively small, the stress is very uniform, and it has good welding performance. It is widely used in parts with high requirements. Disadvantages of ordinary carbon killed steel plate: the surface quality of the killed steel plate is not as good as that of boiling plates, there are concentrated shrinkage holes, and the killed steel plate price is more expensive.
Most common A514 grade Q quenched and tempered steel steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled A514 grade Q quenched and tempered steel steel plates.
35SiMn steel chemical elements: C: 0.32-0.40, Si: 1.10-1.40, Mn: 1.10-1.40. The mechanical properties of 35SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 45; impact energy: 47J. 35SiMn steel belongs to alloy quenched and tempered steel with good properties and can be used instead of 40Cr steel. After quenching and tempering, A514 grade Q quenched and tempered steel, 35SiMn steel has high static strength, fatigue strength, wear resistance, good toughness, good hardenability and medium plasticity during cold deformation.
With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel A514 grade Q quenched and tempered steel product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue. We promise all our steel materials are manufactured and tested in accordance with responding standards. We will take full responsibility for the quality of the steel materials we provide.
