Our company has A242 Type 1 weather resistant steel sheet strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply A242 Type 1 weather resistant steel sheet deep processing service for products A242 Type 1 weather resistant steel sheet like cutting, drilling, bending, welding and grinding.
12Cr2Mo1R steel plate is a kind of Cr-Mo alloy steel, which is a widely used heat-strength steel and hydrogen-resistant steel. As alloy elements such as Cr and Mo are added to low carbon steel, the comprehensive properties of the steel A242 Type 1 weather resistant steel sheet are greatly improved, such as good high temperature mechanical properties, high temperature oxidation resistance, corrosion resistance, good toughness, process performance and weldability.
20G steel is a common carbon steel used to manufacture boilers. The performance of 20G steel is basically the same as that of 20# steel. The requirements for impact toughness, strain aging impact value and cold bending of 20G steel are increased. The yield ratio of 20G steel is slightly higher, and certain fatigue and corrosion resistance are required for A242 Type 1 weather resistant steel sheet steel to ensure the safe operation of boilers. 20G steel is suitable for manufacturing marine boilers, steam boilers and other boiler accessories with pressure less than 6Mpa and wall temperature less than 450 ℃.
The effect of elements in A242 Type 1 weather resistant steel sheet, wear-resistant steel plate on high-temperature temper embrittlement can be divided into: (1) Impurity elements such as phosphorus, tin, antimony and so on that cause the high-temperature temper brittleness of the wear-resistant steel plate. (2) Alloy elements that promote or slow down the brittleness of high temperature tempering in different forms and degrees. Chromium, manganese, nickel, silicon, etc. play a promoting role, while molybdenum, tungsten, titanium, etc. play a retarding role. Carbon also plays a catalytic role.
S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. A242 Type 1 weather resistant steel sheet, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.
There is a silo technology R&D center in our company with many experts. Our technical backbones go abroad to study advanced technologies regularly to make our technology and products leading in the world. We provide our customers with A242 Type 1 weather resistant steel sheet high-quality steel plates, the excellent quality from specialty.
