Will EN steel grade S460NL material rust?
Our company's power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
P355NL1 steel tensile strength Rm:630-450MPaIf high demands are made on notch impact strength and aging resistance It is mainly used in steam boiler and pressure vessel construction P355NL1 plates can be processed with all known welding methods Welding is possible both with the machine and by hand Preheating is usually not necessary unless the outside temperature is below 5°C Then preheating to about 150°C is recommended,EN steel grade S460NL material.
EN steel grade S460NL material,In the manufacturing process of boiler pressure components, raw materials must undergo complex processing deformation and welding, so the steel used to manufacture the boiler must also have good process performance. All materials used to manufacture pressure parts must conform to the relevant national standards for boiler steel. The defects such as delamination, non-metallic inclusion, porosity and looseness in the steel shall be as few as possible, and white spots and cracks are not allowed.
The performance of heat treatment process reflects the difficulty of heat treatment and the tendency of defects of the steel. It mainly includes hardenability, superheat sensitivity, temper embrittlement tendency and oxidation decarburization tendency. The hardenability of alloy steel is high. The cooling method can be used slowly during quenching, which can reduce the deformation and cracking tendency of the workpiece. The addition of Mn and Si will increase the superheat sensitivity of steel. The strengthening effect of alloy elements on steel in quenching and tempering state is the most significant.EN steel grade S460NL material
S355NL steel plate, under EN10111 standard S355NL steel plate, under EN10111 standard, we can regard S355NL steel plate as Fine-grain structural steels, normalised rolled. S355NL steel plate is one mainly of Fine-grain structural steels, normalised rolled, The normalized rolled fine-grain structural steel S355NL is characterized by a minimum yield strength of 355 MPa, by good weldability and high resistance to brittle fracture, which is same with DIN:TStE355 and BS:55EE
