Wuxi Q345R Steel Plate Gas Cutting – Extra Thick Steel Plate Flame Cutting – Medium And Thick Plate Zero Cutting Processing

Wuxi Q345R steel plate gas cutting – extra thick steel plate flame cutting – medium and thick plate zero cutting processing

Regarding the cutting and blanking of Q345R steel plates, if you choose the wrong processing factory, the final cost may be 30% more than the normal cost, which means you have spent extra money. The bosses in Wuxi who are engaged in steel structure and pressure vessel related work need to completely settle this account within today's time.

Don’t choose the cutting method randomly

In the local processing factories in Wuxi, there are basically three mainstream cutting methods. The first is flame gas cutting, the second is CNC plasma, and the third is laser.

If it is a sheet like Q345R, once the thickness is more than 20 millimeters, it is most cost-effective to go the gas cutting route. But if it is less than 20 millimeters, it is better to use CNC, because the cutting accuracy can be stable within 0.1 millimeter. In this case, we do not need to spend more money on the laser.

Many customers directly brought the drawings and asked for the price, but the thickness, material, and accuracy requirements were all not clearly marked. This forced the processing factory to quote a price based on the most expensive production process. Therefore, it is recommended that before sending the drawing, you must write these key parameters clearly and clearly, so that the quoted prices will be comparable, and it will also save everyone from having to argue back and forth later.

Q345R is not an ordinary midboard

Q345R is a material that is specially used to make pressure vessel steel plates. You see, the yield strength is 345 MPa. Once this number is laid out, it is completely different from the ordinary Q345B hot-rolled medium plate. They are not the same at all.

If you are in Wuxi, Shagang and Nanjing Iron and Steel, these manufacturers can supply, this is true, but please note that Q345R has very strict requirements on batch consistency, and the welding performance is also very picky, so you must check the warranty when receiving the materials. It will not work without this procedure.

For those who are working on storage tanks, spherical tanks, and pressure vessel projects, the control of cutting residual stress is a core link. Because gas cutting will cause the heat-affected zone to become larger, it is recommended to use CNC flames with subsequent recovery processing for thick plates. Please don’t just focus on the unit price of cutting. The cost of subsequent processing also needs to be calculated.

Don’t confuse galvanized cold plate with hot rolled plate

In the Wuxi market, it is common to mix different types of materials such as galvanized sheets, cold sheets, and hot-rolled sheets for quotation. There are many such situations.

When components such as gutters, as well as sinks, expansion joints, car mangers, and boxes are processed using galvanized sheets and cold plates, the cost difference between the two can reach about 20% to 30%. If you choose the wrong material , it will directly lead to wasted money, and it will also have a negative impact on weather resistance.

Our factory is equipped with shears, bending machines, rolling machines and punches. Once the drawings are drawn, there is no need to send them out for processing from blanking to molding. This is much more reliable than the method of finding a shop to do the cutting, and then moving to another place to find another person to do the bending. In terms of the total cost, this can save at least 20% of the cost, and the construction period can also be shortened by half.

How much is the difference between CNC and flame?

Referring to the market data in Wuxi in the past two years, the cost of flame cutting medium-thick plates made of Q345R is approximately RMB 80 to RMB 120 per ton, while the cost of CNC cutting is approximately RMB 200 to RMB 350 per ton.

When the thickness of the plate exceeds one hundred millimeters, the economic cost advantages of flame cutting will become more obvious. Therefore, for such extremely thick plates, the flame cutting process is basically chosen for processing.

However, when the CNC method is used for discharging operations, there is no need to perform the edge trimming step, and the processed parts can directly enter the next process.

If we calculate the general ledger, we also include the labor costs required for subsequent polishing and trimming. For medium-thick plates, CNC machining may not be more expensive than flame cutting. The key point is that it depends on your accuracy requirements and the specific arrangements for your subsequent processes.

Why save money by integrating blanking, riveting and welding?

When cutting, blanking, bending, riveting and welding are all completed in the same factory, the workpiece does not need to undergo secondary transportation, which directly cuts down the loss and the amount of waiting-related cycle time. Any large-scale machinery manufacturer equipped with more than ten pieces of equipment can ensure that there are no interruptions or interruptions in the intermediate links of the entire production process by relying on one production line to produce finished products.

If you go to three companies separately, each company will earn a price difference, so the total quotation will be fifteen to twenty percent higher than that of a company that provides integrated services. This situation is particularly evident in those processing parts with small batches and multiple varieties. It is much less troublesome to let one company negotiate than to piece together the resources of three companies.

How to negotiate local quotation in Wuxi

There are more than 40 steel plate processing plants concentrated in Liangxi District and Huishan District of Wuxi, and competition is fierce. Directly ask three companies for long-term cooperation prices, single-time zero-cut prices, freight and tax packages, which do not include Wuxi Q345R steel plate gas cutting-extra-thick steel plate flame cutting-medium-thick plate zero-cut processing. It is only fair to make a horizontal comparison. Nearby Q345 steel plate cutting, blanking, riveting and welding integrated services , don't make a decision just by looking at one company.

Don't just focus on the processing fee. You must find out who will recycle the edges of the scrap, what the minimum order quantity is, and how long the delivery cycle will take.

The weight of each large-sized plate of Q345R size must be at least two to three tons, so the method of transportation and the radius of the loading area will directly determine the final landing cost.

I would like to ask whether the Q345R material you currently have is a thick plate type or a thin plate type? You are welcome to leave a message in the comment area with specific specifications and thickness data? I will give you a rough estimate of the processing cost range.
