High temperature (creep temperature above) boiler steel plate, generally indicates low alloy heat-resistant steel, the commonly used are chrome molybdenum steel, chrome molybdenum vanadium steel, chrome molybdenum tungsten steel, etc. For example, 15CrMoG and 12Cr1MoVG boiler steel plate in GB713 and gr 22 and gr 91 boiler steel plate in ASME SA387/SA387M. High temperature boiler steel plate is mainly used to manufacture high temperature pressure parts such as high temperature header end cover, steam pipe plug plate, etc.shipyard use A131 DH32 hull steel plate
Our company doesn't need the cheapest quotation to choose international logistics company, but the price performance ratio will be high, the service will be good, and the transportation must be safe and punctual, which will not affect the time when the goods arrive at the destination, and the logistics situation will be well communicated with customers in advance. Therefore, when we choose international logistics companies, we will have a look at their timeliness and service attitude in advance. It is only important to transport goods according to the requirements of customers for logistics.
Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.shipyard use A131 DH32 hull steel plate
The final heat treatment of quenched and tempered alloy steel is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.
The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.shipyard use A131 DH32 hull steel plate
In addition, according to customs statistics, from January to February, 7.81 million tons of steel were exported, 2.04 million tons of imported steel, and 6.01 million tons of net exported steel were converted into crude steel, a year-on-year decrease of 33.7%. According to the above data, the average daily supply of crude steel in China from January to February was 2478200 tons, down 5.09% from December of last year, up 3.70% year on year. Compared with the situation of delayed demand, steel production keeps growing, and the market presents a situation of supply exceeding demand.
