1.8909 steel thickness tolerance

1.8909 steel, 14MnNbq plate is a structural steel plate for bridges, which is a low-alloy high-strength steel. 14MnNbq is a special steel plate for the manufacture of bridge structural parts. The end of the steel grade marked with q is the acronym for bridge. The thickness of the bridge steel plate is 6-60mm, which is used to make riveted and bolt-welded structure of road bridges and railway bridges, including sea-crossing bridges.

The main raw material of 1.8909 steel, hot rolling coil is billet. After heating the billet, the strip made from the coarse and fine rolling mill is cooled to a certain temperature by specific cooling, and then the cooled steel strip is made into rolled steel strip by coiler. But generally, according to the buyer's demand, the manufacturer can further process the cooled steel strip into steel plate or flat coil and other products.

We have a large number of 1.8909 steel steel materials in stock, and provide deep processing services such as welding. In addition to simple welding parts, we can also weld H-beam, box column and other profiles. For such welded structure, our advantage is that there are high-quality and low-cost raw material steel plates, which can be cut into the 1.8909 steel required size and welded into steel products with required shape and size, without being limited by the specifications of rolling production lines.

The theoretical weight of seamless steel pipe is the weight per meter of steel pipe calculated by the calculation formula: meter weight = (outer diameter - wall thickness) * wall thickness * 0.02466, in which the outer diameter refers to the farthest distance between the outer walls on both sides of the steel pipe, and the wall thickness is the thickness of the seamless steel pipe wall. The weight per meter of 1.8909 steel seamless steel pipe is calculated by the formula. If you want to get the weight of the whole seamless steel pipe, you should multiply the actual length of the steel pipe.
