Ningbo port has initially formed an all-round three-dimensional collection and distribution network of expressways, railways, aviation, river sea intermodal transport, water to water transfer, etc.

Plasma cutting has a wide range of applications. With different working gas, it can cut various kinds of metals that are difficulty to handle by oxygen cutting. Plasma cutting is fast and efficient when cutting metal with small thickness. The 15mm S690QL alloy steel plate cutting speed can reach more than 10m/min. Plasma cutting can get a clean, neat, non stick slag cutting surface, while the deformation and thermal effect of the incision are small, its hardness change is little, and the cutting quality is good.

We participated the National Railway tender of Bangladesh with our local agent together, and won the 1000 tons corten steel sheets order. The corten steel sheets are used to make train carriage. We finished production of the 1000 tons corten steel 15mm S690QL alloy steel plate sheets within 40 days, and arranged SGS test for the customer before shipment. The customer gave very high comments to our product and service quality, as well as fast delivery.

Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of 15mm S690QL alloy steel plate, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).
