A514 grade R alloy steel plate,SM490B steel, is a kind of low carbon welded structural steel. With this low carbon equivalent, it can produce good cold forming properties. SM490B steel plate is usually supplied in hot rolling or controlled rolling delivery conditions. The SM490B is commonly used in the engineering and construction industries. It has high yield and tensile strength, and provides a variety of processing and testing options to make it highly available in your construction projects.
20G steel is boiler steel, which is similar to No. 20 carbon steel. The difference is that 20G steel has higher and stricter inspection standards than , No. 20 carbon steel for harmful impurities and internal defects. That is to say, 20G steel is specially produced for boiler pressure vessels. It is special purpose "No. 20 carbon steel". The use of 20G steel to make boilers is not because it is more resistant to burning than other steels such as , but because of its strength, toughness, ductility, weldability, temperature influence, fatigue fracture, price and cost, etc 20G steel is most suitable for use in medium and low pressure boilers,A514 grade R alloy steel plate.
Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.A514 grade R alloy steel plate
40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785A514 grade R alloy steel plate
