Effect of laser welding technology on weld microstructure of denisty of 09CuPCrNi-B

Our company is China's 10th largest supplier & Exporter of stainless steel, carbon steel plate and section, alloy steel plate and pipes. We are specialized in stocking & distributing various Stainless Steel, carbon steel plates, denisty of 09CUPCRNI-B angle steel, H beam steel to worldwide for specific & urgent requirements. We have a fully advanced and modernized warehouse that stores tonnes of our value-adding denisty of 09CUPCRNI-B products, which we source out from the mills that are compliant with the universal guidelines for plate production.

Composite steel plate is a composite steel plate which is made of carbon steel or low alloy steel as the base material and coated with stainless steel, titanium alloy, denisty of 09CUPCRNI-B and other composite materials, or sandwiched with other metal or non-metal materials between two layers of steel and processed by pressure or blasting. It is mainly used to make chemical equipment and chemical storage tank, or obtain special functions such as shock absorption. The manufacturing methods of composite steel plate include rolling method and explosion method, but most of them are rolling method.

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 denisty of 09CUPCRNI-B 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 ℃.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This denisty of 09CUPCRNI-B production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate denisty of 09CUPCRNI-B size.

Our denisty of 09CUPCRNI-B, GB/T 1591-2008 Q460D plates are supplied with thickness up to 100mm. Below is our product stock list: 12*1730*8200, 28.58*2172*12100, 22.23*2181*12000, 28.58*2172*12300, 28.58*2171*12100, 35*2200*3500, 22.23*2182*12200, 28*3720*9400, 22.23*2182*12000, 35*2200*3800, 22.23*2125*12000, 24*3000*8850, 22.23*2075*12000, 14*2405*7610, 28.58*2172*12300, 48*2590*7000, 28.58*2172*11400, 75*1800*3500, 120*2040*9150.
