Test method for hardness of TStE380 carbon steel plate sheet

A medium tensile, low carbon manganese steel S355JR is readily weldable and possess good impact resistance. This material is commonly supplied in the untreated or normalized condition. Structural unalloyed steel TStE380 carbon steel plate sheet has a wide range of applications in construction, metallurgy, heavy and transport engineering, machine tool, power engineering and bridge building industries. Various profiles and metal structures, parts and elements of ground and underground equipment are made from steel S355JR.

The hardness of the steel plate is very high, so special equipment is needed to complete the processing and cutting of these materials, TStE380 carbon steel plate sheet. In order to cut the plate into an ideal size, the steel plate cutting needs to use natural gas flame for preheating, which will generate a large amount of oxygen flow during the operation. These substances will oxidize the steel plate, and then form a cutting edge, then the cutting operation process is basically completed. In the actual processing work, there are many different classifications for steel plate cutting.

The TStE380 carbon steel plate sheet, thin steel plates are more convenient for cutting. Since the thickness of the thin steel plate is basically below 4mm, it is very easy to construct during cutting, which also reduces the work intensity of the construction personnel and speeds up the work efficiency of cutting. There are different materials for thin steel plates, such as ordinary carbon steel, high-quality carbon structural steel, alloy structural steel, carbon tool steel, stainless steel, spring steel, silicon steel for electrical engineering, etc..

The European Iron and Steel Industry Union (Eurofer) has sent a letter to the president of the European Commission, asking the Commission to review the existing trade safeguard measures immediately, proposing to reduce the steel import quota by 75% within six months to help the European steel industry cope with the current difficult situation; For imported steel exceeding the quota, the tariff rate can be reduced to less than 25%. Europe has also proposed restrictions on TStE380 carbon steel plate sheet and so on steel imports related to crisis and safety.
