Export steel nm500 coil thickness 1220-4200mm width range

Generally, the production process of steel NM500 coil thickness seamless steel tube can be divided into cold rolling and hot rolling. The production process of cold-rolled seamless steel tube is generally more complicated than that of hot rolling. The tube blank must be first rolled by three rolls, and then be subject to sizing test and cutting after extrusion. Then enter the annealing process. In appearance, the cold-rolled seamless steel tube is shorter than the hot-rolled seamless steel tube, and the wall thickness of the cold-rolled seamless steel tube is generally smaller than that of the hot-rolled seamless steel tube, but the surface looks brighter than the thick wall seamless steel tube, the surface is not too rough, and the diameter is not too much burr.

EN10083-3 42CrMo4 steel plate delivery status: Heat treatment (normalizing, annealing or high temperature tempering) or non-heat treatment delivery status should be specified in the contract. EN10083-3 42CrMo4 steel plate equivalent materials: JIS SCM440, AISI 4140, GB 42CrMo, steel NM500 coil thickness etc. EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness.

The hot rolling method is to heat the steel NM500 coil thickness steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of steel NM500 coil thickness rolling process is usually called semi-finished product production, also called blank production.

BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the steel NM500 coil thickness hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.
