New breakthrough of NM450 steel grade

The hot rolling method is to heat the NM450 steel grade 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 NM450 steel grade rolling process is usually called semi-finished product production, also called blank production.

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer.

Medium and thick plates NM450 steel grade are mostly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, etc. Medium and thick plates can also be used to make all kinds of containers, furnace shells, furnace plates, automobile static steel plates and so on. Among them, shipbuilding steel plate is used to make marine and inland ships. The shipbuilding steel plate NM450 steel grade is required to have high strength, plasticity, toughness, good cold bending performance, welding performance and corrosion resistance.
