This is the second year we have been golden supplier on Alibaba. Over the decades, we have accumunited rich customer resources and have established stable copperation with many customers all over the world. So we did not reply on 09CuPTiRE-B cold rolled steel coil B2B platforms. But with the development of the company and the increasing of the company reputation, it is necessery for us to open up more channels for customers to reach us.
After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of 09CuPTiRE-B cold rolled steel coil, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.
15Mo3 steel plate is used for boiler and high temperature pressure vessel.15Mo3 steel plate executive standard: DIN17155Delivery status of 09CuPTiRE-B cold rolled steel coil, 15Mo3 steel plate: normalizingNormalizing temperature of 15Mo3 steel plate: 650 ~ 700 ℃Normalizing time of 15Mo3 steel plate: 1.5t-2.5t15Mo3 welding repair: welding repair can only be carried out after the approval of the purchaser.Requirements for tensile properties of 15Mo3 steel plate: tensile strength 450-600 MPa, yield strength 270 MPa.
