API 5L Gr. A is mainly used for steel of large diameter pipeline. LR AH40 shipbuilding structural plate, API 5L Gr. A is mainly used for pressure liquid transportation, oil, natural gas, water and other liquid transportation, oilfield engineering, pipeline engineering, construction, steel pipe and oil and gas engineering using pipeline.
At the same time of doing well in LR AH40 shipbuilding structural plate production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the LR AH40 shipbuilding structural plate technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
Medium and thick steel plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on. However, each project has different requirements for plate size. How to cut LR AH40 shipbuilding structural plate, medium and thick steel plates? There are many ways, for example, flame cutting, laser cutting, wire cutting, plasma cutting, ultra-high pressure water cutting and so on.
The effect of elements in LR AH40 shipbuilding structural plate, wear-resistant steel plate on high-temperature temper embrittlement can be divided into: (1) Impurity elements such as phosphorus, tin, antimony and so on that cause the high-temperature temper brittleness of the wear-resistant steel plate. (2) Alloy elements that promote or slow down the brittleness of high temperature tempering in different forms and degrees. Chromium, manganese, nickel, silicon, etc. play a promoting role, while molybdenum, tungsten, titanium, etc. play a retarding role. Carbon also plays a catalytic role.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel LR AH40 shipbuilding structural plate plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
