Grade usage of NM400 steel plate for welded boilers
Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and usage of NM400 steel plate resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, usage of NM400 steel plate new materials, and promotes the competition of enterprises Struggle.
ASTM A633 material is particularly suited for service at low ambient temperatures and higher where notch toughness better than that expected in as-rolled material of a comparable strength level is desired. usage of NM400 steel plate, A633 Grade E high-strength low-alloy structural steel provides a minimum yield point of 60 ksi [415 MPa] in thicknesses up to 4.0 in. [100 mm], inclusive and 55 ksi [380 MPa] in thicknesses over 4 in. to 6 in. [100 to 150 mm], inclusive.
Unlike general steel manufactures, other than regular fresh production, we also have huge stocks. What is more, we offer cutting, welding, drilling, bending, etc. deep processing for the steel materials. That enable us to meets various usage of NM400 steel plate steel sizes and shapes requirements of clients.So, if you have any steel demands, or steel processing needs, please do not hesitate to contact with us. We will try our best to make you stisfied.
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 usage of NM400 steel 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 usage of NM400 steel 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 usage of NM400 steel 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. usage of NM400 steel 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.
Our company regularly visits customers, consults and follows up the after-sales service, and directly solves problems for customers. In the use of our steel materials, whether quality problems or not, the after-sales will help solve the problem as soon as possible. We promise free life-long replacement for any product quality problems. The sound after-sales service system make you free from worries.
