Shipbuilding steel is a kind of steel plate used by shipyards, shipbuilding companies and dockyards to manufacture hulls of cargo and passenger ships, boats, offshore drilling platforms, gateways and other structures and vessels. The company also supply AB AH36 plates and steel sheets cutting of NM400 plate in coils or cut to length, steel profiles (steel bulb flats, rounds and squares), and round and profiled tubes made from shipbuilding steel grades. Shipbuilding steel is produced under the control of certifying societies, sea and river registers.
S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the cutting of NM400 plate rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of cutting of NM400 plate steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
Galvanized ASTM A36 steel angle Hot-dip galvanized steel angle is ideal for outdoor applications or corrosive environments where black cutting of NM400 plate steel angles could be badly corroded in short time. The amount of galvanization is made according your requirements. Product description: Item: A36 Angle Steel. cutting of NM400 plate Standard: ASTM A36. Technology: Hot Rolled. Type: Equal & Unequal. Surface: black or galvanized. Equal angle: Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 to 20 mm. Length: 6 m, 9 m, 12 m or per your request. Unequal angle: Size: 30 × 20 to 250 × 90. Thickness:3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.
Steel transportation because of the special material of cutting of NM400 plate steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
