09CuPTiRE-B steel factory plate weldability

We have 4 typical production lines 09CuPTiRE-B steel factory, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.

According to the data of the General Administration of Customs, in April 2020, China exported 6.311 million tons of 09CuPTiRE-B steel factory and so on steel, down 2.6% from March, down 0.3% year on year; from January to April, China exported 20.601 million tons of steel, down 11.7% year on year. In April, China imported 1.044 million tons of steel, down 11.70% from March; from January to April, China imported 4.184 million tons of steel, up 7.4% year on year.

Heat treatment is a very important process to improve the performance of 09CuPTiRE-B steel factory etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, 09CuPTiRE-B steel factory, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.
