hardess of nm500 steel plate sheet properties and usage
The shipbuilding and offshore platform steel plates are our main products. The shipbuilding and offshore platform steel plates are produced according to ASTM A131/A131M technical standard. Our shipbuilding and offshore platform steel plates accept ABS, LR,CCS, RINA, DNV GL, BV, NK, KR, RMRS and so on classification societies’ inspection and will obtain EN10204 3.2 MTC. The typical shipbuilding and offshore platform steel grades are grade A/B/D/E, AH32, DH32, EH32, FH32, AH36, DH36, EH36, FH36, AH40, DH40, EH40, FH40, etc.
Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, hardess of NM500 steel plate weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction. Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent.
Hardess of NM500 steel plate,Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process They need to be heated to 1100 ° C to 1250 ° C for rolling This rolling process is called hot rolling Rolling at room temperature is generally understood as cold rolling However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling,hardess of NM500 steel plate.
